All About Gemstones

Written by the Gemology Team at Myra Gems. With more than 30 years of experience sourcing and grading natural gemstones across India, our team has guided over 30,000 customers in finding the right stone. All gemological information in this article reflects current trade practice and Vedic astrological tradition as practised in India. The information in this article is for educational purposes. Consult a qualified Vedic astrologer before wearing any gemstone. Two Blue Sapphires can sit side by side, look almost identical to a first-time buyer, and carry prices that differ by ten times. One is a clean Ceylon stone with an even velvety colour. The other is darker, cloudy, and over-saturated to the point that it reads as ink rather than blue. The difference is not luck or magic. It is gemstone quality grading, the structured way professionals read a stone before deciding what it is worth. In India, where the same Neelam (the Sanskrit name for Blue Sapphire, traditionally linked to the graha Shani) might be bought for astrology, for jewellery, or for long-term value, understanding quality is the single most useful skill a buyer can build. Most people in India choose a gemstone the way they choose vegetables: by colour and by feel. That instinct is not wrong, but it is incomplete. A Pukhraj (Yellow Sapphire, associated with Guru, the planet Jupiter) can look bright and golden and still be a weak stone underneath, hiding fractures or a hollow centre. Quality lives in the relationship between four core factors, colour, clarity, cut, and weight, and in three quieter ones, transparency, lustre, and treatment. This article walks through each factor the way our gemologists assess stones every day, with plain tests you can use yourself, real examples from the Indian market, and a gemstone-by-gemstone guide so you know exactly what good looks like for Neelam, Pukhraj, Manik, Panna, Moti, and Moonga. What Does Gemstone Quality Grading Actually Mean? Gemstone quality grading is the process of judging a stone against a fixed set of measurable factors rather than relying on first impressions or seller claims. The core factors are colour, clarity, cut, and carat weight, supported by transparency, lustre, and treatment status. A high-quality gemstone is one that scores well across these factors together, not one that simply looks pretty at a glance. Coloured stones are graded differently from diamonds. With diamonds, the famous four Cs are weighted heavily toward clarity and colourlessness. With coloured gemstones such as sapphire, ruby, and emerald, colour carries the most weight, and a degree of inclusion is normal and even expected. A flawless-looking emerald should make a buyer suspicious, not excited, because natural Panna almost always carries internal features. Why Grading Matters More in the Indian Market In India, the same stone serves three buyers with three different priorities. The astrology buyer wants a natural, untreated stone that fits a specific ratti weight and birth chart. The jewellery buyer wants colour and sparkle at a fair price. The investment buyer wants origin, size, and rarity that will hold value. Quality grading is the common language that serves all three, because every one of these goals depends on reading the stone correctly. The Vedic View of Gemstone Quality The idea of grading gemstones is not new to India. The classical Sanskrit treatise on gem examination, the Ratnapariksha, describes judging stones by evenness of colour, freedom from cracks, and clarity of the body, the same instincts modern gemology formalised centuries later. According to Vedic astrology, a flawed or cracked stone is considered unsuitable for wearing, which is why quality is treated as a spiritual concern in Indian tradition, not only a commercial one. This is one reason buyers here have always cared about a clean stone. Colour: The Most Important Factor in Gemstone Quality Colour is the most important factor in gemstone quality for almost every coloured stone. Gemologists break colour into three parts: hue, the basic colour; tone, how light or dark it is; and saturation, how pure and vivid it is. The finest stones show a strong, pure hue at a medium tone with high saturation, with no grey, brown, or black muddying the colour. The most common mistake Indian buyers make is assuming that darker means better. It does not. A Blue Sapphire so dark it looks black under indoor light has poor tone, even though it may feel "powerful" in the hand. A Ruby that is so deeply red it turns purple or brownish has drifted away from its ideal hue. The traditional guidance is to look for a colour that stays alive and clear under different lights, not the deepest possible shade. How to Read Hue, Tone, and Saturation at Home You do not need a laboratory to assess colour. Move the stone between natural daylight near a window and ordinary indoor light. A quality stone holds its colour and stays bright in both. A weaker stone goes flat, grey, or dead under one of the two lights. This shift is called colour zoning when it appears as uneven patches within the same stone, and even, consistent colour across the whole gem is a clear sign of quality. For Blue Sapphire, the trade describes the ideal as a vivid "Ceylon blue," named after Sri Lanka, a velvety cornflower tone that is neither inky nor washed out. For Emerald, the prized colour is a pure grass green with a slight bluish undertone, the look associated with Colombian and Zambian material. Browse the range of natural Blue Sapphire rings at Myra Gems to train your eye on what an even, well-saturated blue should look like across different weights. Colour and Astrological Suitability According to Vedic astrology, the colour of a gemstone is tied to the planet it represents, which is why colour quality and astrological value move together. A clean, evenly coloured Pukhraj is traditionally believed to carry the influence of Guru more clearly than a pale or patchy stone. Astrologers recommend choosing a stone whose colour is natural and unforced, since an over-treated or dyed colour is considered inauthentic in tradition. Colour, in the Indian context, is both an aesthetic and a sacred test. The Ideal Colour for Each Major Gemstone The ideal colour is different for every gemstone, so a buyer should learn the target shade for their specific stone rather than applying one rule everywhere. For Blue Sapphire, the prized look is a pure, slightly violet-tinged blue at a medium tone, the velvety Ceylon blue that stays bright in daylight. For Yellow Sapphire, the ideal runs from a clean lemon yellow to a warm golden, always transparent and never muddy. For Ruby, the target is a vivid, pure red, with the trade reserving its highest praise for a rich red that shows neither brown nor too much purple. For Emerald, the finest colour is a saturated grass green with a faint bluish secondary tone, lively rather than dark. For Pearl, colour gives way to lustre, with a clean white to cream body and a strong surface glow valued most. For Coral, an even red to orange-red with a smooth, waxy polish marks quality, while patchy or dyed-looking colour signals a weaker stone. Comparing several stones of the same gemstone against these targets is the quickest way to calibrate your eye to true quality. Choosing a Gemstone Worth Wearing Every stone we set begins with a natural, hand-selected gem graded for even colour and life. Our gemologists reject stones that go grey or dead under daylight, so what reaches you is colour you can trust. Explore our hand-selected gemstone rings Clarity and Inclusions: How to Judge a Clean Gemstone Clarity in coloured gemstones means how free the stone is from visible inclusions, the natural internal features formed when the crystal grew underground. A natural, untreated gemstone can be identified by these inclusions, which act like a fingerprint of genuine origin. The grading goal is not zero inclusions, which usually signals glass or synthetic material, but inclusions that do not disturb the eye or weaken the stone. The trade term for the ideal is "eye-clean," meaning no inclusions are visible to the naked eye at a normal viewing distance of about a foot. An eye-clean Ruby or Sapphire is considered high clarity. Emerald is judged on a gentler scale because its internal garden of inclusions, called the "jardin" in the trade, is inherent to the species and accepted as part of its character. Inclusions That Help and Inclusions That Hurt Not all inclusions are equal. Fine needle-like inclusions called "silk" in sapphire and ruby can actually scatter light beautifully and confirm natural origin. What matters for quality is whether an inclusion is positioned where it disturbs the colour or sits near the surface where it threatens durability. Acceptable inclusions: tiny crystals, light silk, and healed feathers deep inside the stone that do not catch the eye. Quality-reducing inclusions: large dark crystals near the centre, surface-reaching cracks, and cloudy zones that dull the whole stone. Warning signs: perfectly clean stones at a suspiciously low price, or round gas bubbles, which point to glass imitation rather than natural gem. A Simple Clarity Test for Indian Buyers Hold the stone under a single bright light and tilt it slowly. Inclusions will appear as tiny lines, dots, or veils inside. If you see nothing at all in a coloured stone priced low, treat that as a red flag rather than a triumph. At Myra Gems, our gemologists regularly encounter customers who reject a fine natural Panna because it has a visible jardin, not realising that an utterly clean "emerald" at that price is almost always treated quartz or glass. A real Emerald earns its character honestly. View the natural Emerald rings collection to see how a healthy, lively jardin looks in a quality Panna. Cut and Shape: Why Proportion Affects a Gemstone's Look Cut is the factor most buyers underrate, yet it controls how much of a stone's colour and brilliance you actually see. A well-cut gemstone returns light evenly across its surface and shows colour edge to edge. A poorly cut stone leaks light through the bottom, creating a pale, glassy patch in the centre known as a "window," or a dark dead zone called "extinction." Two stones of identical colour and weight can look completely different purely because of cut. In the Indian market, cut is often sacrificed to preserve weight, because stones are frequently priced and worn by ratti. A cutter may leave a stone too deep or too bulgy to keep its weight above a target, and the result is a heavy stone that looks dull. The most important factor when buying a gemstone for both beauty and value is to reward good cutting, not just raw size. How to Spot a Good Cut Without Tools Look straight down at the face of the stone under a light. A well-cut gem shows lively flashes across the whole surface. If you see a clear see-through patch in the middle where you can read text behind the stone, that is windowing, and it lowers quality. Tilt the stone: if a large area goes black, that is extinction, often caused by a stone cut too deep. Shape, Symmetry, and Polish in Cut Quality Beyond brilliance, cut quality includes the symmetry of the stone and the smoothness of its polish, both of which affect how clean a gem looks on the finger. A symmetrical stone has an even outline, a centred face, and matching proportions on both sides, while a lopsided or off-centre cut looks awkward however good the colour. Run the stone slowly under light and watch the reflections: a well-polished surface gives crisp, mirror-like flashes, whereas a poorly finished stone shows a slightly hazy or scratched face. Shape itself is a matter of preference, but it interacts with quality. Ovals and cushions tend to hold colour well and suit most astrological settings, rounds maximise light return, and emerald cuts show off clean material but expose any inclusions plainly. The traditional guidance is to choose a shape that flatters the stone's colour and clarity rather than one that simply preserves the most weight. A balanced shape with neat symmetry and a clean polish is a quiet but reliable marker of a carefully cut gem. Cut Choices for Astrological Stones The traditional guidance is that an astrological stone should make full skin contact through the open back of the setting, which is why oval and cushion cuts with smooth backs are popular for Vedic rings. According to Vedic astrology, the stone should be set so it touches the finger, and a clean, well-proportioned cut supports both the look and the intended contact. Gemologists recommend a cut that balances colour, light return, and the practical needs of an astrological ring, rather than an extreme cut chosen only to save weight. Carat Weight vs Ratti: Understanding Size and Value in India Carat is the international unit of gemstone weight, equal to 0.2 grams, while ratti is the traditional Indian unit used for astrological stones. One ratti is roughly 0.91 carats, so the two are close but not identical, and confusing them is one of the most common sources of buyer disputes in India. Weight affects price sharply, but it is only valuable when the other quality factors are also strong. A larger stone is not automatically a better stone. A five-ratti Neelam that is dark, windowed, and full of surface cracks is worth far less than a clean, well-cut two-ratti stone with even colour. Price per carat also rises steeply with size for top material, because large clean stones are rare, which means a big stone of poor quality is a poor purchase at any price. Carat to Ratti Conversion for Buyers Indian buyers are often advised by astrologers to wear a specific ratti weight based on their chart. When you shop, confirm whether a seller is quoting carats or ratti, since the small difference adds up on larger or pricier stones. The traditional guidance is to fix the ratti requirement with your astrologer first, then look for the best quality stone available at that weight, rather than chasing the heaviest possible gem. Matching Weight to Purpose For everyday jewellery, a moderate weight with excellent colour and cut often gives the most pleasing result. For astrology, the prescribed ratti weight guides the choice, with quality maximised within that target. For investment, larger sizes of fine natural material in sought-after origins hold value best. You can filter stones by ratti weight across the full gemstone rings range to match weight to budget and purpose without overpaying for size alone.

Transparency, Lustre and Treatment: The Hidden Quality Markers Transparency and lustre are the quieter quality factors that separate an average stone from an exceptional one, while treatment status sits at the heart of authenticity. Transparency describes how freely light passes through the stone, graded from transparent to translucent to opaque. Lustre describes how brightly the polished surface reflects light. A quality gemstone is usually highly transparent with a bright, glassy lustre that makes the colour glow rather than sit flat. A stone can have good colour yet still feel lifeless if it is cloudy or "milky," meaning light scatters inside instead of passing through cleanly. This milkiness lowers value even when the hue is correct. Lustre, meanwhile, depends on both the species and the quality of the final polish, and a dull, scratched surface points to a rushed cut or a softer, lower-grade stone. Understanding Gemstone Treatments Treatment refers to anything done to a stone after mining to improve its appearance, and disclosure of treatment is central to honest grading. Heating is the most common and widely accepted treatment for sapphire and ruby, used to improve colour and clarity, and a stone described as "natural, unheated" sits at the top of the quality and price scale. More aggressive treatments such as glass filling in ruby, oiling in emerald, or dyeing change how a stone should be valued, and a natural, untreated stone is traditionally preferred for astrological use. According to Vedic astrology, an unheated and untreated stone is believed to carry the planet's influence in its purest form, which is why astrologers recommend natural stones for serious astrological wearers. This is a matter of tradition rather than medical fact, and buyers should treat it as such. Durability and Hardness as Quality Factors Durability is a practical part of quality, because a stone meant for daily wear must resist scratches and knocks. Hardness is measured on the Mohs scale, where Sapphire and Ruby score a very high 9, making them excellent for everyday rings, while Emerald sits around 7.5 to 8 but is more brittle due to its jardin, and Amethyst sits near 7. A softer or more fractured stone is not lower quality in colour, but it does demand gentler wear and protective settings. For a ring worn constantly, our gemologists weigh durability alongside beauty, since a stone that chips easily will disappoint over time no matter how fine its colour. How Origin Influences Quality Origin shapes the typical quality profile of a stone because different mines produce different characteristics. Ceylon, the old name for Sri Lanka, is associated with bright, lively Blue Sapphires. Burma and Mozambique are known for rich Ruby colour. Colombia and Zambia are the classic emerald origins. Over more than three decades of sourcing stones from origins such as Sri Lanka, Burma, and Mozambique, our team has observed that origin sets the starting point for quality, but the individual stone still has to be judged on its own colour, clarity, and cut. Origin is a guide, not a guarantee. How Quality Differs Across the Navratna Gemstones Quality looks different for each gemstone because every species has its own ideal colour, its own normal clarity, and its own common pitfalls. The table below summarises what good quality means for the most popular stones in India, so you can judge each one on its own terms rather than applying a single rule to all. This gemstone-by-gemstone view is the fastest way for a buyer to know what to look for before purchasing. Gemstone Quick Answer: What good quality looks like Common quality pitfall Best starting point for most buyers Even colour, eye-clean to lightly included, lively cut, natural origin Buying for size or darkness alone Blue Sapphire (Neelam) Velvety Ceylon blue, medium tone, high transparency Over-dark, inky stones that go black indoors Yellow Sapphire (Pukhraj) Bright lemon to golden yellow, clean, transparent Pale, washed-out colour or hidden cracks Ruby (Manik) Vivid pure red, eye-clean, strong lustre Brownish or purplish tone, glass-filled fractures Emerald (Panna) Pure grass green, accepted natural jardin Suspiciously clean stones, heavy oiling Pearl (Moti) Smooth round shape, strong even lustre, clean skin Dull surface, visible blemishes, off-round shape Coral (Moonga) Even red to orange-red, smooth polish, no pits Dyed colour, surface pits, dull finish Reading the Table for Your Own Stone Use the row for your chosen gemstone as a checklist when you view a stone in person or in clear photos. For Manik, the Sanskrit name for Ruby and the gem of Surya, the Sun, prioritise a pure red that is neither brown nor purple. For Moti, the pearl of Chandra, the Moon, lustre and a clean skin matter more than perfect roundness. Compare stones within a single species, never across species, since a "clean" Emerald and a "clean" Ruby mean very different things. See how these standards play out across our Ruby rings collection and Yellow Sapphire rings. When to Prioritise Which Factor For sapphire and ruby, colour and transparency lead. For emerald, balance colour against an acceptable jardin. For pearl and coral, surface quality and lustre lead, because these are organic gems with their own rules. The traditional guidance is to learn the priorities of your specific stone first, then grade within them. Quality in Semi-Precious Stones Semi-precious stones follow the same logic with their own targets, and quality still rests on colour, clarity, and lustre. A fine Amethyst (Jamunia) shows a deep, even purple without grey zoning. A good Cat's Eye (Lehsunia) is judged mainly on its chatoyancy, the sharp, mobile band of light across the dome, which should be bright, centred, and straight. Opal (Doodhiya) is graded on its play of colour, with broad, vivid flashes across the stone preferred over weak or patchy fire. Garnet (Gomed) and Golden Topaz (Sunahara Pukhraj) are valued for clean transparency and warm, even colour. Across all of these, the same principle holds: even colour, honest clarity, and a bright surface signal a quality stone. Common Gemstone Quality Mistakes to Avoid When Buying in India The most common gemstone quality mistakes in India are buying for darkness, chasing weight over colour, trusting a single flattering light, and assuming a flawless stone is a good stone. Each of these errors leads buyers to overpay for a weaker gem or to walk away from a finer one. Knowing the mistakes in advance is often more useful than memorising the grading rules, because most poor purchases come from a small set of repeated errors. Confusing Darkness with Strength Many buyers in India equate a darker stone with a more powerful one, especially for Neelam and Manik. In reality, an over-dark stone has poor tone and looks black or muddy in ordinary light. The traditional guidance is that a clean, evenly coloured stone carries the planet's influence more clearly than a dark, lifeless one, so darkness should never be the deciding factor on its own. Paying for Ratti Instead of Quality When buyers fix on a ratti number before anything else, sellers can meet that weight with a poorly cut or heavily included stone. A large, dull gem at the right ratti is a worse buy than a clean, lively stone of similar weight. Gemologists recommend setting the ratti requirement with your astrologer, then maximising colour, clarity, and cut within that target. Judging a Stone Under One Light A single warm spotlight can flatter a weak colour and hide cloudiness, which is why shop lighting is rarely a fair test. Always view a stone in daylight near a window as well as under indoor light. A quality gemstone holds its colour and life in both, while a weaker stone collapses under one of the two. Believing Flawless Means Better A coloured stone that looks completely flawless to the naked eye, especially at a low price, is more likely to be glass or synthetic than a natural treasure. Natural gemstones almost always carry some inclusions, and Emerald in particular is expected to show its jardin. Treating a perfectly clean budget stone with suspicion rather than excitement protects buyers from the most common imitation. To compare honest natural stones against these mistakes, browse the complete gemstone rings collection. What to Know Before Buying a Gemstone: Advice from Myra Gems' Gemologists The single most useful habit before buying is to view a stone under at least two different light sources, because light is where most quality problems reveal themselves. A stone that looks rich under the warm yellow light of a shop can fall apart under daylight near a window. Gemologists recommend never finalising a stone under a single dramatic spotlight, which is exactly the lighting many sellers use to hide a weak colour. Over years of handling thousands of stones, our team has learned details that only repeated experience teaches. Here are the tips we share with customers most often. Tilt before you trust. A quick tilt under light exposes windowing and extinction that a flat, face-up photo will always hide. A customer choosing a Neelam for Saturn's mahadasha will often focus only on colour, and a simple tilt test saves them from a windowed stone. Distrust the flawless bargain. In our experience, a coloured stone that is both perfectly clean and unusually cheap is the most reliable warning sign in the entire market. Natural stones earn their inclusions. Judge colour, then weight, never the reverse. Buyers who fix on a ratti number first often end up with a large, dull stone. Fix quality first, then meet your weight target as closely as the budget allows. Watch the back of the stone. Cloudiness, cracks reaching the surface, and dye sitting in pits often show most clearly from behind, which is why our gemologists always turn a stone over before approving it. Compare like with like. Place two stones of the same species next to each other in the same light. Quality differences that are invisible alone become obvious side by side. These are practical, repeatable checks. None of them require equipment, and all of them come from the simple discipline of looking at a stone the way a grader does rather than the way a hopeful buyer does. Three Decades of Honest Gemstone Grading Myra Gems brings more than 30 years of gemstone expertise and the trust of over 30,000 customers across India to every stone we select. Each gem is hand-graded by our in-house team for colour, clarity, cut, and natural origin before it ever reaches a ring. Discover gemstones graded by our experts Frequently Asked Questions About Gemstone Quality Grading Q: What is the most important factor in gemstone quality? A: Colour is the most important factor in gemstone quality for nearly every coloured stone, including Blue Sapphire, Ruby, and Emerald. Gemologists assess colour through hue, tone, and saturation, looking for a pure, vivid colour at a medium tone with no grey or brown dulling it. Clarity, cut, and weight all matter, but a stone with poor colour cannot be a high-quality stone no matter how large or clean it is. The one exception is organic gems such as Pearl and Coral, where surface quality and lustre lead. For most buyers, learning to judge colour well is the fastest path to choosing a good stone. Q: How can I tell if a gemstone is good quality at home? A: You can assess gemstone quality at home by checking colour under two light sources, looking for inclusions under a single bright light, and tilting the stone to spot windowing. A quality stone holds even colour in both daylight and indoor light, shows natural inclusions without large dark or surface-reaching flaws, and returns light across its whole face without a see-through patch in the centre. Turn the stone over to inspect the back for cracks or cloudiness. These simple visual tests reveal most quality problems without any equipment, and they are the same first checks a professional grader makes. Q: Does a darker gemstone mean better quality? A: No, a darker gemstone does not mean better quality, and this is one of the most common misunderstandings among Indian buyers. The ideal is a medium tone with high saturation, where the colour stays bright and alive under different lights. A Blue Sapphire so dark it looks black indoors, or a Ruby so deep it turns brownish, has drifted past the ideal tone and is worth less than a cleaner, brighter stone. Strength of effect in tradition is linked to a pure, natural colour, not to maximum darkness. Always judge a stone in daylight, where over-dark stones reveal themselves. Q: What is the difference between carat and ratti? A: Carat is the international gemstone weight unit equal to 0.2 grams, while ratti is the traditional Indian unit used for astrological stones, with one ratti equal to roughly 0.91 carats. The two are close but not the same, so a stone quoted in ratti will appear slightly lighter than the same number in carats. Always confirm which unit a seller is using before comparing prices, especially on larger or higher-value stones where the difference adds up. For astrology, fix your required ratti weight with your astrologer first, then choose the best quality stone available at that weight. Q: Do inclusions reduce a gemstone's quality? A: Inclusions reduce quality only when they disturb the eye or weaken the stone, and many natural inclusions are completely acceptable. Tiny crystals, light silk, and deep healed features are normal in natural stones and even help confirm genuine origin. Quality drops when inclusions are large and dark near the centre, when cracks reach the surface, or when cloudiness dulls the whole stone. Emerald is judged gently because its natural jardin is inherent to the species. A coloured stone that appears perfectly flawless at a low price should raise suspicion of glass or synthetic material rather than excitement. Q: Are heated gemstones lower quality than unheated ones? A: Heated gemstones are generally valued below unheated stones of the same colour, but heating is a widely accepted treatment, not a defect. Heat is commonly used on Sapphire and Ruby to improve colour and clarity, and most stones in the market are heated. A natural, unheated stone of fine colour sits at the top of the quality and price scale because such stones are rarer. According to Vedic astrology, unheated and untreated stones are traditionally preferred for astrological wearing, as they are believed to carry the planet's influence in its purest form. This is a matter of tradition, framed as belief rather than scientific fact. Q: Does the origin of a gemstone affect its quality? A: Origin influences the typical quality profile of a gemstone but does not guarantee the quality of any single stone. Ceylon, the old name for Sri Lanka, is associated with bright Blue Sapphires, Burma and Mozambique with rich Ruby colour, and Colombia and Zambia with fine Emeralds. These origins set expectations, yet every stone must still be judged on its own colour, clarity, cut, and transparency. A well-graded stone from a lesser-known origin can outperform a poor stone from a famous one. Treat origin as a helpful guide, not a substitute for examining the actual gem. Q: How much should I pay for a good quality gemstone in India? A: A good quality gemstone's price depends on the species, weight, colour grade, clarity, and whether it is natural and untreated, so there is no single fair price across stones. The most reliable approach is to compare stones of the same species and similar weight, then pay more for better colour, transparency, and cut rather than for size alone. Be cautious of prices that seem far below the market, since deep discounts on coloured stones usually mean treatment, synthetic material, or hidden flaws. Set your weight and budget first, then maximise quality within that range for the best long-term value. Q: Does Myra Gems grade its own gemstones before selling them? A: Yes, every stone at Myra Gems is hand-graded by our in-house gemology team before it is set into a ring. Our gemologists assess each gem for colour, clarity, cut, transparency, and natural origin, rejecting stones that go dull or grey in daylight or that hide surface-reaching cracks. With more than 30 years of gemstone expertise and over 30,000 customers served across India, the team applies the same grading discipline described in this article to every piece. Buyers can also book a free video consultation to see a stone closely and ask questions before deciding. Q: Is a bigger gemstone always better than a smaller one? A: No, a bigger gemstone is not always better, because weight only adds value when colour, clarity, and cut are also strong. A large stone that is dark, cloudy, windowed, or cracked is worth far less than a smaller stone with even colour and a lively cut. Price per carat also climbs steeply for top-quality material as size increases, so a large stone of weak quality is a poor purchase at almost any price. For most buyers, a moderate weight with excellent colour and a clean, well-proportioned cut gives the most pleasing and valuable result. Final Thoughts on Judging Gemstone Quality Gemstone quality grading turns a confusing purchase into a confident one, because it replaces guesswork with a clear order of priorities: colour first, then clarity, cut, and weight, supported by transparency, lustre, and treatment status. Once you learn to judge colour under daylight, tilt a stone to catch windowing, and respect the natural inclusions that prove a stone is real, you can read almost any gem in the Indian market on your own terms. The buyers who avoid disappointment are simply the ones who look at a stone the way a grader does, patiently and in good light. This knowledge protects you whether you are buying for jewellery, for astrology, or for long-term value, and it ensures the stone you choose is one worth wearing for years. The information in this article is for educational purposes, and you should consult a qualified Vedic astrologer before wearing any gemstone. When you are ready to see well-graded natural stones in person, you are welcome to explore the full collection at Myra Gems and judge the quality for yourself.
