How Many Ratti to Wear: Gemstone Weight Guide | Myra Gems

Every week at Myra Gems, we meet customers who arrive with a small slip of paper from their astrologer: a gemstone name, a metal, and a number in ratti. The first question is almost always the same: "What does five ratti actually mean, and how do I make sure I am buying the right weight?" That question is more layered than it looks. Ratti is the traditional Indian unit used in Vedic astrological prescriptions, and it does not map cleanly onto the carat weights you will see on international seller tags. A buyer who does not understand the conversion can easily end up with a stone that is 10 to 15 percent heavier than prescribed, paying proportionally more per carat along the way.

The traditional guidance on how many ratti to wear comes down to one foundational rule: roughly one ratti of gemstone for every ten to twelve kilograms of your body weight. For most adults, this places the recommended weight somewhere between four and seven ratti, which in carat terms is approximately 3.6 to 6.4 carat. But that formula is only the starting point. The final figure depends on the gemstone, the strength of the ruling planet in your birth chart, the purpose of wearing the stone, and a set of traditional weight fractions, Sava, Sadhe, and Pauna, that most buyers have never heard of.

This guide covers all of it. You will leave knowing what ratti means, how it converts to carat, how many ratti to wear for each major astrological stone, what Sava-Sadhe-Pauna means and why Pauna is avoided, and how quality relates to weight when budget is a constraint. The Sanskrit names for each gemstone , Neelam, Pukhraj, Manik, Panna, Moti, Moonga, are used throughout, because these are the terms your astrologer's prescription will carry.

What Ratti Means and Why It Still Governs Gemstone Weight in India

Ratti is the traditional Indian unit of weight for gemstones, and it is the unit Vedic astrologers have used to prescribe stones for centuries. One standardised ratti is approximately 0.91 carat, or 182 milligrams. This means a ratti figure and a carat figure for the same stone will always be different numbers, a detail that trips up a surprising number of buyers every year.

The word ratti comes from the seed of the Gunja plant, known botanically as Abrus precatorius. These small seeds, red with a black tip, were remarkably consistent in mass, which made them a practical natural standard for measuring gold and gemstones in ancient India long before precision scales existed. Classical texts including Buddha Bhatta's Ratnapariksha and the tradition recorded in the Brihat Parashara Hora Shastra recorded gemstone prescriptions in these units, which is why ratti has survived in astrological practice while the rest of India moved to the metric system.

Why the Traditional Unit Persisted in Vedic Astrology

The ratti endures in astrological practice for a straightforward reason: the tradition was transmitted in this unit and continues to be taught in it. When an astrologer studies your birth chart and prescribes a gemstone, the recommendation comes in ratti because that is the language of the texts they trained with. Most practising astrologers in India, particularly in the northern states, inherited their methods from teachers who had never worked in carats at all. The result is a two-system market: prescriptions arrive in ratti while sellers price and weigh in carats. A buyer who cannot translate between the two is working with incomplete information.

At Myra Gems, our gemologists regularly meet customers who arrive with a ratti figure, walk into a jeweller's shop, and accidentally ask for the same number in carats. On a quality stone priced at even Rs 10,000 per carat, the difference between five ratti (4.55 carat) and five carat is 0.45 carat, which translates to Rs 4,500 or more in price difference on that stone alone. Understanding the conversion is not a technicality; it is money.

Kacchi Ratti and Pakki Ratti: The Two Standards in Circulation

There are actually two versions of the ratti used in India, and confusing them is a common and costly error. The older, seed-based value , sometimes called kacchi ratti, is approximately 121.5 milligrams, which reflects the literal weight of a dried Gunja seed and is the standard still used in parts of Punjab and Haryana for gold trading. The trade and astrology standard used across the rest of India , called pakki ratti, is approximately 182 milligrams, which gives the familiar one ratti to 0.91 carat ratio used in gemstone recommendations everywhere from Jaipur to Mumbai.

When your astrologer writes a figure in ratti, they almost certainly mean pakki ratti. When a seller confirms a weight in ratti, ask them explicitly which standard they are using. A gemstone measured in kacchi ratti and sold at a pakki ratti price is a significant discrepancy: the difference between the two values is close to 33 percent. The cleanest way to remove the ambiguity entirely is to confirm the carat weight in writing, since carat is internationally standardised and carries no regional variation.

Ratti to Carat Conversion: The Numbers Every Gemstone Buyer in India Needs

The single most useful conversion to know is that one ratti equals approximately 0.91 carat. To go the other way, one carat is approximately 1.1 ratti. These two figures cover almost every shopping situation you will encounter. Gemologists recommend always confirming the carat weight in writing, because carat is the precise international standard; once you have the carat figure, converting back to ratti is a five-second arithmetic check.

 

How to Apply the Conversion When You Are Shopping

Write down both numbers before you walk into any shop or open any online listing. If your prescription reads six ratti, note that this is approximately 5.46 carat. Ask any seller to quote the stone in carat, then convert back to ratti yourself to verify the match. A stone weighing 5.42 or 5.51 carat is well within the range of a six ratti prescription; natural gemstones rarely fall on a perfectly round number, and chasing a round carat figure for aesthetic reasons means buying outside your prescribed weight. The most important factor when buying any gemstone is ensuring the carat weight on the lab certificate matches your prescribed ratti, converted precisely. You can explore our range of naturally sourced gemstone rings, each listed with its certified weight in carat so you can match your prescription with confidence.

Natural Gemstones in Your Exact Prescribed Weight

Every stone at Myra Gems is certified and listed by weight, so you can match your ratti prescription to the carat figure without guesswork. Our team can also read the two units side by side with you.

Sava, Sadhe and Pauna: The Ratti Fractions Most Buyers Never Hear About

According to Vedic astrology and traditional gemstone practice, the weight of an astrological stone is not simply quoted as a whole number. Each ratti figure carries a fractional designation, Sava, Sadhe, or Pauna, that describes where within the ratti range the stone falls, and one of these fractions is traditionally avoided for astrological wear. This is a detail that almost every general guide on how many ratti to wear leaves out entirely.

The system works by treating each ratti as divided into 100 parts and reading the decimal portion of the weight figure. The three divisions are as follows.

What Sava, Sadhe and Pauna Mean in Practice

Sava (sometimes written Savaya) covers decimal values from .01 to .35. A gemstone weighing 5.01, 5.15, 5.25, or 5.34 ratti is referred to as Sava Paanch Ratti, a sava-five stone. Sadhe covers decimal values from .35 to .75. Gemstones weighing 7.36, 7.40, 7.57, or 7.63 ratti are called Sadhe Saat Ratti, a sadhe-seven stone. Pauna covers decimal values from .76 to .99. Stones weighing 8.81, 8.95, or 8.77 ratti are called Pauna Nau Ratti, a pauna-nine stone.

Among practising astrologers in northern India, Pauna is traditionally considered inauspicious for astrological wear. A stone that falls in the Pauna range, for example 6.77 or 7.82 ratti, is commonly avoided in favour of a stone in the Sava or Sadhe range for the same whole-number figure. This is not a hard rule in every tradition, and some astrologers do not observe it, but buyers shopping in markets like Delhi, Jaipur, or Chandigarh will hear this distinction raised regularly. If your astrologer specifies a weight, ask whether the Pauna range should be avoided for your particular prescription.

Why the Fraction Matters When You Compare Two Stones

Two stones both labelled as "seven ratti" can occupy very different positions within the ratti system. A stone weighing 7.20 ratti is a Sava Saat stone; one weighing 7.55 ratti is a Sadhe Saat stone; and one weighing 7.85 ratti is a Pauna Saat stone. Knowing which category a stone falls into can influence whether your astrologer approves the specific piece you have found. The practical consequence is that when shopping, always ask for the precise decimal weight, not just the rounded ratti figure. A seller who only quotes a whole number is giving you incomplete information.

How Many Ratti to Wear Based on Your Body Weight

The most widely followed formula in Vedic astrological practice is to wear roughly one ratti of gemstone for every ten to twelve kilograms of body weight. According to Vedic astrology, a stone proportionate to the wearer is believed to connect more naturally with its ruling planet. For most adults, this places the recommended weight in the four to seven ratti range, equivalent to approximately 3.6 to 6.4 carat.

This is a starting band, not a final answer. The body-weight formula gives an astrologer and a buyer a sensible baseline; the actual prescription is then adjusted against the birth chart, the condition of the relevant planet, and the intended purpose of the stone. The traditional guidance is to treat this figure as a minimum rather than an exact target; a stone that is too small is considered unable to make adequate skin contact, which in traditional thinking reduces its astrological connection.

Body-Weight Reference Table for Gemstone Ratti

The table below applies the standard formula of one ratti per twelve kilograms for a mid-range estimate, and one ratti per ten kilograms for the higher bound.

 

Why Most Stones Are Worn Between Four and Eight Ratti

In practice, the vast majority of astrological gemstones worn in India fall within the four to eight ratti band. A stone below about four ratti is generally considered too small to sit securely on the finger and maintain consistent skin contact, while one above eight ratti becomes cumbersome in daily wear. An astrological gemstone is traditionally meant to stay on the body every day; comfort and wearability are not separate from astrological considerations but are part of them. At Myra Gems, our gemologists regularly encounter customers who have been told to source a very large stone and return having second thoughts once they see how heavy it sits on the hand. A well-chosen six or seven ratti stone in a thoughtful setting almost always wears better than a ten ratti stone that the wearer leaves in a drawer. Our ring size guide helps you get the band right before you choose the stone, since a stone can only do its work when it is comfortable to wear every day.

How Planet Strength and Mahadasha Shift the Ratti Figure

The body-weight formula gives you a range, but two factors can shift the final prescription significantly within that range. The first is the condition of the governing planet in your birth chart. According to Vedic astrology, a planet that is weak, debilitated, or afflicted in a chart may call for a stone toward the heavier end of the calculated range, since the additional weight is believed to strengthen the planet's influence on the wearer. A planet that is already well placed and strong may need only a modest stone to support it; a lighter weight in the right quality can be more appropriate than a heavy stone of lesser character.

The second factor is the planetary period, or mahadasha, in which the stone is being worn. A gemstone prescribed during the active mahadasha of its ruling planet carries a different astrological weight and purpose than one worn as a long-term supportive stone outside an active period. Some astrologers adjust the ratti prescription specifically for mahadasha wear, favouring a slightly heavier stone during the planetary period when the graha's influence is already heightened. These adjustments cannot be derived from a calculator. They belong to a qualified Vedic astrologer who has read your chart carefully, which is why the body-weight formula is always described as the opening step, not the final answer. For more on how individual stones align with your chart, our gemstone guidance resource covers the essentials at your own pace.

How Many Ratti to Wear for Each Gemstone: Neelam, Pukhraj, Manik, Panna, Moti, Moonga and Lehsunia

Different astrological gemstones are traditionally worn in slightly different weight ranges, because each stone has a distinct governing planet, specific gravity, and role in Vedic practice. As a general rule, the major stones are worn between three and eight ratti, adjusted for body weight and birth chart. The table below summarises the typical guidance for the most commonly worn astrological gemstones in India.

Before the table, one technical note on density that helps explain why two stones of the same ratti weight will not look the same size. Sapphire and ruby are both corundum, which carries a specific gravity of approximately 4.0 and sits at 9 on the Mohs hardness scale. Emerald (specific gravity around 2.7, Mohs 7.5 to 8) is noticeably less dense, so a five ratti Panna looks physically larger than a five ratti Neelam. Pearl, being an organic gem with a specific gravity of approximately 2.7 and no crystalline hardness to speak of, looks largest of all at the same ratti weight. Coral sits at a specific gravity close to 2.65. These differences are why gemologists never judge ratti weight by appearance alone.

Gemstone Ratti Reference Table

How Many Ratti of Neelam (Blue Sapphire) Should You Wear?

Blue Sapphire, known as Neelam and linked to Shani or Saturn, is typically worn in the three to six ratti range. According to Vedic astrology, Shani is considered one of the more powerful and swift-acting grahas, and most traditions counsel against starting with a very heavy stone. Sourcing matters: Ceylon Neelam from Sri Lanka, prized for its clean blue with a slight violet undertone, commands a significant premium over stones of similar weight from other origins. At Myra Gems, the Neelam stones we source from Sri Lanka and Bangkok cutting centres consistently show the fine silk inclusions and natural colour zoning that distinguish natural unheated material from heated equivalents. A stone in the four to five ratti range in Ceylon quality, lab-certified by GIA or IGI, will outperform a heavier but lower-grade stone on every astrological and aesthetic measure.

How Many Ratti of Pukhraj (Yellow Sapphire) Should You Wear?

Yellow Sapphire, known as Pukhraj and ruled by Guru or Brihaspati, is traditionally worn in the four to seven ratti range. Guru is associated in Vedic tradition with wisdom, learning, and prosperity, and Pukhraj is among the most commonly prescribed stones in India. Ceylon Yellow Sapphire, which carries a warm golden yellow at a specific gravity of 4.0, is the most sought-after origin for astrological wear. A 60 kg person lands naturally around five to six ratti under the body-weight formula, which in carat terms is 4.55 to 5.46 carat, a range that corresponds to a noticeable, wearable stone without becoming bulky. You can see how different weights look as finished pieces in our collection of Yellow Sapphire rings.

How Many Ratti of Manik (Ruby) Should You Wear?

Ruby, known as Manik and linked to Surya or the Sun, is worn between three and six ratti in most prescriptions. Surya in Vedic astrology is traditionally associated with authority, confidence, and leadership, and Manik is prescribed when the Sun is weak or requires strengthening. Burmese ruby, sometimes described in the trade as pigeon-blood for its deep red with a slight blue undertone, is the most revered origin for astrological wear. Ruby shares its specific gravity of approximately 4.0 with sapphire, so a five ratti Manik and a five ratti Neelam will look nearly identical in size. Lab certification from GRS or IGI confirming natural origin and absence of glass filling is particularly important for ruby, since fracture-filling is widespread in lower-quality material.

How Many Ratti of Panna (Emerald) Should You Wear?

Emerald, known as Panna and ruled by Budh or Mercury, is most commonly worn between four and seven ratti. Budh is linked in Vedic tradition to intelligence, communication, and commerce. Panna is one of the stones where the density difference is most visible: with a specific gravity around 2.7, compared to sapphire's 4.0, a five ratti Panna looks noticeably larger on the hand than a five ratti Neelam. Colombian emeralds are the most prized in the international trade for their warm, slightly yellowish green, while Zambian material tends toward a deeper, cooler tone. Both origins produce stones used for astrological wear; origin is a quality context, not a guarantee. A natural, untreated emerald can be identified by its characteristic inclusions, known in the trade as jardin, which are visible under magnification and serve as evidence of natural formation. Explore our range of Emerald rings to see certified Panna in a variety of weights.

How Many Ratti of Moti (Pearl) Should You Wear?

Pearl, known as Moti and ruled by Chandra or the Moon, is typically worn in the four to eight ratti range. Pearl's low specific gravity of approximately 2.7 means a given ratti weight looks physically larger than the same weight in sapphire or ruby; a five ratti Moti will appear meaningfully bigger on the hand than a five ratti Neelam. Because of this density difference, pearl is often prescribed at slightly higher ratti weights than crystalline gemstones. Chandra is associated in Vedic tradition with mind, emotions, and cycles, and is considered one of the gentler grahas. Natural saltwater pearls from the Gulf of Mannar have historically been the most revered in the Indian astrological tradition, though certified natural pearl from any trusted origin serves the purpose. Our Pearl rings are sourced from verified natural origins and certified for authenticity.

How Many Ratti of Moonga (Red Coral) Should You Wear?

Red Coral, known as Moonga and ruled by Mangal or Mars, is traditionally worn at slightly higher ratti weights than most crystalline stones, typically between five and nine ratti. Mangal is associated in Vedic astrology with energy, courage, and assertiveness, and Moonga is among the most commonly prescribed stones for those in whose charts Mars is weak or afflicted. Coral is an organic gemstone with a specific gravity close to 2.65, and its lower density means it wears lighter than its ratti weight suggests. Mediterranean and Japanese origins are the most commonly traded for astrological purposes. A clean, deep-red Moonga without surface treatments, certified for natural origin, is preferable to a larger but porous or dyed specimen. Those looking for Moonga set in an appropriate metal can browse our Coral rings.

How Many Ratti of Lehsunia (Cat's Eye) Should You Wear?

Cat's Eye, known as Lehsunia and ruled by Ketu, is worn between four and seven ratti in most astrological prescriptions. Ketu is regarded in Vedic tradition as a karmic and spiritually significant graha, and Lehsunia is handled with some care; many astrologers recommend a trial period before committing to long-term wear. Chrysoberyl Cat's Eye from Sri Lanka is the most prized variety for astrological use, valued for the sharp chatoyant band, known in the trade as the "milk and honey" effect, that runs across the cabochon when light strikes it. The chatoyancy requires a clean, well-proportioned cabochon cut rather than a faceted cut, which means the stone's appearance is governed by the quality of the optical phenomenon rather than brilliance in the conventional sense.

Why Gemstone Quality Matters More Than How Many Ratti You Wear

A smaller, well-formed, eye-clean natural gemstone is widely regarded in the gemstone trade as a more valuable purchase than a larger stone that is heavily included, dull, or poorly cut. The most important factor when buying a coloured gemstone is not the ratti figure: it is the quality of the material within that weight range. Weight is only one of the four pillars of coloured stone valuation, alongside colour, clarity, and cut.

Colour leads. An even, well-saturated Neelam in Ceylon blue, a vivid pigeon-blood Manik, or a clean golden-yellow Pukhraj commands a premium in proportion to its colour quality that weight alone cannot replicate. Clarity follows: an eye-clean stone, meaning one in which no inclusions are visible to the naked eye under normal viewing conditions, is a significantly higher-quality purchase than a stone of the same ratti riddled with visible fractures or cloudiness. Cut governs how well the stone returns light and how the final piece looks once set in metal.

Does Weight Affect Size Differently for Each Stone?

It does, substantially. Because gemstones differ in specific gravity, a given ratti weight produces a very different physical size depending on the material. Sapphire and ruby at a specific gravity of approximately 4.0 are among the densest common gemstones, so they present as compact stones for their weight. Emerald, coral, and pearl, all in the 2.65 to 2.7 range, look noticeably larger at the same ratti weight. This is why a buyer comparing a five ratti Neelam and a five ratti Panna side by side will see stones of markedly different physical dimensions, even though the weight figures match.

A natural, untreated gemstone can be identified by its natural inclusions and growth features, which an experienced eye reads over years of handling stones. At Myra Gems, over more than three decades of sourcing stones from Sri Lanka, Jaipur's cutting centres, and Bangkok trading hubs, our gemologists have learned that the most common returns for re-evaluation involve stones where surface colour is uneven or where inclusions visible under 10x magnification were not disclosed at the point of sale. A laboratory certificate from IGI or GRS confirms weight and origin; a trusted gemologist's eye confirms what the certificate does not always show.

The Honest Trade-Off: Quality Against Ratti When Budget Is Limited

The traditional and practical advice is consistent: when budget forces a trade-off, choose a smaller stone of better quality over a larger stone of poor quality. A clean, well-coloured natural gemstone slightly below the maximum of your ratti range will almost always give more satisfaction over years of daily wear than a heavy but lifeless stone. Quality also affects longevity: a well-cut, correctly set stone wears durably, resists chipping, and maintains its appearance through the daily contact that astrological wear demands. A stone you remove because it is too heavy or catches on clothing is not serving its intended purpose. For more on how origin and treatment affect a stone's character and value, our guide on heated versus unheated gemstones is worth reading before you make a final decision.

Common Myths About Ratti and Gemstone Weight That Cost Buyers Money

Several persistent myths about how many ratti to wear lead buyers into costly or avoidable mistakes. Clearing them up before you shop is one of the most useful things this guide can do.

Is a Heavier Ratti Always More Powerful?

The biggest myth is that a heavier stone always produces a stronger astrological effect. The traditional guidance in Vedic practice is that the correct weight for your chart, not the maximum possible weight, is what matters. A stone that exceeds your recommended ratti band does not amplify the planet's influence proportionally; in some traditional interpretations, an excessively heavy stone relative to the chart can be counterproductive. Most prescriptions settle between four and eight ratti precisely because this range represents the point where the stone is heavy enough to make genuine skin contact without being cumbersome. Bigger is not better in Vedic practice; proportionate is.

Are Ratti and Carat Interchangeable?

No. One ratti is approximately 0.91 carat, so treating the two as the same unit causes a systematic overshoot of roughly 10 percent in the weight of every stone you buy. On an expensive gemstone priced per carat, a 10 percent weight difference is a meaningful cost difference. A five ratti prescription is about 4.55 carat, not five carat. If you ask a seller for five carats when your prescription says five ratti, you are buying the wrong weight and paying for it.

Does a Very Small Stone Below Three Ratti Work for Astrological Wear?

In traditional practice, very small stones are generally considered less suitable for astrological use, because a stone that barely makes contact with the skin is believed to maintain a weaker connection with the body and, through it, with the ruling planet. This is one reason most prescriptions fall in the four to eight ratti band rather than at the very bottom of the scale. For certain stones, certain charts, or tight budgets, smaller weights are used, and a qualified astrologer is the appropriate person to approve that adjustment. The body-weight formula exists precisely because it provides a starting figure that produces adequate presence without excess.

Should You Round a Ratti Prescription Up to the Nearest Carat?

Rounding a ratti figure upward to a tidy carat number is a habit that quietly costs buyers money. A five ratti prescription is 4.55 carat. Rounding this to five carat means buying a stone heavier than prescribed and paying for 0.45 carat more at the per-carat price of a fine gemstone. On a quality Pukhraj priced at Rs 15,000 per carat, that rounding adds Rs 6,750 to your bill. A stone weighing 4.52 or 4.58 carat is perfectly in keeping with a five ratti prescription. Natural stones rarely land on round carat numbers, and chasing one is an aesthetic preference that has no astrological basis.

Does the Same Ratti Weight Suit Every Person?

No single ratti figure suits every person for the same gemstone. Body weight and birth chart both shape the prescription, and two people of identical build may receive different ratti recommendations depending on the condition of the governing planet in each of their charts. This is exactly why the body-weight formula is a starting band rather than a final answer, and why the Sava-Sadhe-Pauna fractions matter: the precise decimal position of the stone you buy is, in many traditions, as relevant as the whole-number ratti figure.

What Experienced Gemstone Buyers Know Before They Choose a Ratti: Tips from Myra Gems' Gemologists

Choosing how many ratti to wear is simpler when you know the practical checks that prevent most buying errors. The following tips come from our gemology team's decades of sourcing, setting, and handing natural gemstones to customers across India.

Decide the weight range before you visit any seller. Buyers who shop without a fixed ratti target often stretch toward a more impressive stone emotionally, then find they own something too heavy to wear comfortably every day. Fix your range first, then choose within it.

Confirm the weight in both ratti and carat in writing before paying. The most common avoidable error our team sees is a buyer matching a ratti prescription against a carat weight without converting. Write down the prescribed ratti, convert it to carat, and check that the stone on offer falls within that carat band before committing. If a seller cannot give you the weight in writing, that is itself a signal.

Ask about the decimal: Sava, Sadhe, or Pauna. Once you know the whole-number ratti target, ask the seller for the precise decimal weight and check whether it falls in the Pauna range. If your astrologer observes the Pauna restriction, a stone at 6.82 ratti may not be acceptable when one at 6.25 or 6.55 ratti would be. This is a conversation to have before purchase, not after.

Judge colour in natural daylight, not under shop lighting. Showroom lighting is tuned to flatter stones. A Pukhraj or Neelam that looks vivid under a spotlight can read quite differently by a window. Our team routinely walks customers to natural light before they decide, because colour is the quality factor that ages best.

Remember that density changes how a stone looks. A pearl and a sapphire of the same ratti weight will not look the same size on the hand. Judge weight by the certified figure, not by appearance.

Think about the setting and daily wearability. A stone is traditionally worn so it touches the skin, which influences the ring design. Getting your ring size right matters as much as the stone itself; a stone set too loosely or in an uncomfortable setting will spend time off the hand rather than on it. Getting your ring size accurate before you choose the stone avoids a common and easily preventable problem.

When budget is limited, lean toward quality over ratti. A clean, well-coloured stone slightly below your maximum ratti will satisfy you for years more reliably than a heavy stone with poor colour or visible flaws. This is the single piece of advice our team repeats most often, because it is the one most buyers later wish they had followed. For those exploring their options by zodiac sign and governing planet, our zodiac gemstone guide provides context before the weight conversation begins.

Frequently Asked Questions About How Many Ratti to Wear

Q: How many ratti gemstone should I wear?

A: The traditional guideline is to wear roughly one ratti of gemstone per ten to twelve kilograms of body weight, which places most adults in the four to seven ratti range, approximately 3.6 to 6.4 carat. A person weighing 60 kg typically lands around five to six ratti under this formula. This is a starting band only; the final weight should be adjusted to your birth chart by a qualified Vedic astrologer, who will consider the condition of the ruling planet and the purpose of wear. Always convert your ratti prescription to carat before shopping, since most sellers weigh stones in carat rather than ratti.

Q: How do I convert ratti to carat for my gemstone?

A: Multiply the ratti figure by 0.91 to get the approximate carat equivalent. One ratti is approximately 0.91 carat. For example, five ratti is about 4.55 carat, and seven ratti is about 6.37 carat. To go the other direction, multiply carats by approximately 1.1 to get ratti. This conversion matters because astrologers prescribe in ratti while sellers and lab certificates use carat. Always ask the seller for the carat weight in writing and convert it back to ratti yourself to verify the match before purchasing.

Q: What are Sava, Sadhe and Pauna in gemstone ratti?

 A: Sava, Sadhe, and Pauna are traditional names for the fractional portions of a ratti weight. Sava refers to decimal values from .01 to .35 above a whole number, for example 5.25 ratti is Sava Paanch Ratti. Sadhe covers .35 to .75, so 7.55 ratti is Sadhe Saat Ratti. Pauna covers .76 to .99, and is traditionally considered inauspicious for astrological wear by many astrologers, particularly in north India. If your astrologer observes the Pauna restriction, avoid stones in that decimal range and choose one in the Sava or Sadhe range for the same whole-number target.

Q: How many ratti of Neelam (Blue Sapphire) should I wear?

A: Blue Sapphire, known as Neelam and ruled by Shani (Saturn), is most commonly worn between three and six ratti, adjusted to body weight and birth chart. Because Saturn's influence is considered powerful in Vedic astrology, most traditions recommend approaching Neelam within this moderate range rather than choosing a very heavy stone. Convert your prescribed ratti to carat before shopping and ask for a lab certificate from GIA or IGI confirming the stone is natural and unheated. The specific gravity of sapphire is approximately 4.0, so a five ratti Neelam will be a compact but weighty stone.

Q: How many ratti of Pukhraj (Yellow Sapphire) should I wear?

A: Yellow Sapphire, known as Pukhraj and governed by Guru (Jupiter), is traditionally worn between four and seven ratti. Pukhraj is among the most commonly prescribed astrological stones in India, linked in Vedic tradition to wisdom and prosperity. A 60 kg person typically falls around five to six ratti under the body-weight formula, equivalent to roughly 4.55 to 5.46 carat. Confirm the exact weight with your astrologer, convert to carat, and check the decimal to ensure the stone falls in the Sava or Sadhe range rather than Pauna if your tradition observes that distinction.

Q: How many ratti of Moonga (Red Coral) should I wear?

A: Red Coral, known as Moonga and ruled by Mangal (Mars), is generally worn between five and nine ratti, which is slightly higher than most crystalline astrological gemstones. Coral's lower specific gravity of approximately 2.65 means it weighs less for its visible size, which is part of why prescriptions tend toward the higher end of the ratti scale. A natural, untreated Moonga of deep, even red, certified for origin, is preferable to a larger but porous or treated specimen. Confirm the carat weight in writing and check where the decimal falls against the Sava-Sadhe-Pauna system.

Q: Why do astrologers use ratti instead of carat?

 A: Astrologers use ratti because it is the unit embedded in the classical Vedic and gemstone texts through which the tradition was transmitted across generations. The ratti derived originally from the Gunja seed, which was a consistent natural weight standard in ancient India. Texts such as the Ratnapariksha of Buddha Bhatta and the tradition of the Brihat Parashara Hora Shastra recorded gemstone prescriptions in ratti, and practising astrologers learned the system in this unit. Carat is the modern international standard, introduced to create a uniform global measure, and the two systems now coexist in the Indian gemstone market.

Q: Is a heavier ratti gemstone always more powerful in Vedic astrology?

A: No. The traditional guidance in Vedic practice is that the correct weight for your birth chart matters far more than the maximum possible weight. A stone that exceeds your recommended ratti band is not considered more effective; in some interpretations it can be counterproductive. The four to eight ratti range that most prescriptions fall into exists precisely because this band provides adequate skin contact without excess bulk. Quality, particularly colour, clarity, and natural origin, consistently outweighs raw weight as a measure of a stone's value for astrological purposes.

Q: Should I choose higher ratti or better quality when my budget is limited?

A: Choose better quality over higher ratti when budget is limited. A smaller natural gemstone with clean clarity and strong, attractive colour is regarded in the trade as a more valuable purchase than a larger stone that is dull, included, or treated. Quality also affects how a stone performs over years of daily wear, which matters because astrological gemstones are worn continuously. A clean, well-coloured stone slightly below your maximum ratti will almost always give more satisfaction over time than a heavier stone of poor character.

A: Myra Gems offers a full range of natural, certified gemstones listed by carat weight so you can match your ratti prescription exactly. Every stone at Myra Gems is lab-certified by recognised bodies including GIA and IGI, sourced from verified origins, and our team can help you read ratti and carat side by side so you leave with exactly what your prescription calls for. With more than 30 years of experience and over 30,000 customers served across India, Myra Gems is India's first natural gemstone jewellery brand. Our gemstone guidance resource explains the buying process in detail before you visit.

Q: What is the difference between kacchi ratti and pakki ratti?

A: Kacchi ratti is the older, seed-based standard of approximately 121.5 milligrams per ratti, still used in parts of Punjab and Haryana, particularly for gold trading. Pakki ratti is the trade and astrology standard of approximately 182 milligrams per ratti, used across the rest of India and equivalent to roughly 0.91 carat. When an astrologer or gemstone seller in most of India quotes a weight in ratti, they almost always mean pakki ratti. If you are buying in the Punjab or Haryana region, confirm which standard the seller is using, since the difference of roughly 33 percent between the two values significantly affects both the size and price of the stone.

Choosing How Many Ratti to Wear: What to Take Away from This Guide

The decision on how many ratti to wear rests on three pillars working together. The body-weight formula of one ratti per ten to twelve kilograms gives you a sensible starting range, which for most adults falls between four and eight ratti. A qualified Vedic astrologer then adjusts that figure to your birth chart, the condition of the governing planet, and any active mahadasha. And quality, specifically colour, clarity, and natural origin of the stone, determines how much value you actually receive within whatever weight you choose. Converting your ratti prescription to carat before shopping, checking the Sava-Sadhe-Pauna fraction if your tradition observes it, and asking for the certified weight in writing are the three practical steps that remove almost all the confusion buyers encounter.

For more than thirty years, the team at Myra Gems has walked customers from a handwritten ratti figure to a certified, well-sourced stone. The pattern has always been the same: clarity on the unit, honesty about quality, and a weight that genuinely suits the wearer and their chart. The information in this article is for educational purposes. Please consult a qualified Vedic astrologer before wearing any gemstone. When you are ready to see what your recommended weight looks like as a finished piece, take the time to choose well.

FAQ

Q: How many ratti gemstone should I wear?

A: The traditional guideline is to wear roughly one ratti of gemstone per ten to twelve kilograms of body weight, which places most adults in the four to seven ratti range, approximately 3.6 to 6.4 carat. A person weighing 60 kg typically lands around five to six ratti under this formula. This is a starting band only; the final weight should be adjusted to your birth chart by a qualified Vedic astrologer, who will consider the condition of the ruling planet and the purpose of wear. Always convert your ratti prescription to carat before shopping, since most sellers weigh stones in carat rather than ratti.

Q: How do I convert ratti to carat for my gemstone?

A: Multiply the ratti figure by 0.91 to get the approximate carat equivalent. One ratti is approximately 0.91 carat. For example, five ratti is about 4.55 carat, and seven ratti is about 6.37 carat. To go the other direction, multiply carats by approximately 1.1 to get ratti. This conversion matters because astrologers prescribe in ratti while sellers and lab certificates use carat. Always ask the seller for the carat weight in writing and convert it back to ratti yourself to verify the match before purchasing.

Q: What are Sava, Sadhe and Pauna in gemstone ratti?

A: Sava, Sadhe, and Pauna are traditional names for the fractional portions of a ratti weight. Sava refers to decimal values from .01 to .35 above a whole number, for example 5.25 ratti is Sava Paanch Ratti. Sadhe covers .35 to .75, so 7.55 ratti is Sadhe Saat Ratti. Pauna covers .76 to .99, and is traditionally considered inauspicious for astrological wear by many astrologers, particularly in north India. If your astrologer observes the Pauna restriction, avoid stones in that decimal range and choose one in the Sava or Sadhe range for the same whole-number target.

Q: How many ratti of Neelam (Blue Sapphire) should I wear?

 A: Blue Sapphire, known as Neelam and ruled by Shani (Saturn), is most commonly worn between three and six ratti, adjusted to body weight and birth chart. Because Saturn's influence is considered powerful in Vedic astrology, most traditions recommend approaching Neelam within this moderate range rather than choosing a very heavy stone. Convert your prescribed ratti to carat before shopping and ask for a lab certificate from GIA or IGI confirming the stone is natural and unheated. The specific gravity of sapphire is approximately 4.0, so a five ratti Neelam will be a compact but weighty stone.

Q: How many ratti of Pukhraj (Yellow Sapphire) should I wear?

A: Yellow Sapphire, known as Pukhraj and governed by Guru (Jupiter), is traditionally worn between four and seven ratti. Pukhraj is among the most commonly prescribed astrological stones in India, linked in Vedic tradition to wisdom and prosperity. A 60 kg person typically falls around five to six ratti under the body-weight formula, equivalent to roughly 4.55 to 5.46 carat. Confirm the exact weight with your astrologer, convert to carat, and check the decimal to ensure the stone falls in the Sava or Sadhe range rather than Pauna if your tradition observes that distinction.

Q: How many ratti of Moonga (Red Coral) should I wear?

 A: Red Coral, known as Moonga and ruled by Mangal (Mars), is generally worn between five and nine ratti, which is slightly higher than most crystalline astrological gemstones. Coral's lower specific gravity of approximately 2.65 means it weighs less for its visible size, which is part of why prescriptions tend toward the higher end of the ratti scale. A natural, untreated Moonga of deep, even red, certified for origin, is preferable to a larger but porous or treated specimen. Confirm the carat weight in writing and check where the decimal falls against the Sava-Sadhe-Pauna system.

Q: Why do astrologers use ratti instead of carat?

 A: Astrologers use ratti because it is the unit embedded in the classical Vedic and gemstone texts through which the tradition was transmitted across generations. The ratti derived originally from the Gunja seed, which was a consistent natural weight standard in ancient India. Texts such as the Ratnapariksha of Buddha Bhatta and the tradition of the Brihat Parashara Hora Shastra recorded gemstone prescriptions in ratti, and practising astrologers learned the system in this unit. Carat is the modern international standard, introduced to create a uniform global measure, and the two systems now coexist in the Indian gemstone market.

Q: Is a heavier ratti gemstone always more powerful in Vedic astrology?

A: No. The traditional guidance in Vedic practice is that the correct weight for your birth chart matters far more than the maximum possible weight. A stone that exceeds your recommended ratti band is not considered more effective; in some interpretations it can be counterproductive. The four to eight ratti range that most prescriptions fall into exists precisely because this band provides adequate skin contact without excess bulk. Quality, particularly colour, clarity, and natural origin, consistently outweighs raw weight as a measure of a stone's value for astrological purposes.

Q: Should I choose higher ratti or better quality when my budget is limited?

A: Choose better quality over higher ratti when budget is limited. A smaller natural gemstone with clean clarity and strong, attractive colour is regarded in the trade as a more valuable purchase than a larger stone that is dull, included, or treated. Quality also affects how a stone performs over years of daily wear, which matters because astrological gemstones are worn continuously. A clean, well-coloured stone slightly below your maximum ratti will almost always give more satisfaction over time than a heavier stone of poor character.
