What Is Jade? A Complete Guide to the Stone, Its Species and Its Value

What the Word Jade Actually Covers

Jade is a trade name, not a mineral name. Gemmologists use it for two distinct materials, and the two have different chemistry, different hardness and different price levels.

The first is jadeite, a sodium aluminium silicate from the pyroxene family. The second is nephrite, a calcium magnesium silicate from the amphibole family. Both are aggregates of many tiny crystals rather than single gems.

Chinese uses a wider term. Yu can mean any fine ornamental stone, and it has been applied to jade, to serpentine, to quartz and to soapstone over the centuries.

That gap between the English and Chinese terms explains most of the confusion in the market. A seller may be honest and still describe two different stones as jade.

For a buyer, the practical question is always the same: which of the two minerals is in front of me, and has it been treated?

The commercial consequence is easy to see in a listing. A title that uses only the word jade is not lying, it is simply incomplete. Two bracelets at the same price can be different materials, with different durability and very different resale. That is why the species matters more than the label on the box.

The Two Minerals Behind the Name

Jadeite forms deep in subduction zones, where oceanic crust is pushed under a continent. The pressure is high and the temperature is moderate, and the crystals grow tightly interlocked.

Nephrite forms in a different setting. It appears where hot fluids react with serpentinite, and it grows as a felted mass of tremolite fibres too fine to see without magnification.

That fibrous structure is the reason nephrite feels smooth and resists breaking. Jadeite is more granular, so it polishes to a harder, glossier surface.

The table below is the short version. A full comparison of Jadeite and Nephrite covers the optical tests and the market implications.

Property	Jadeite	Nephrite
Chemistry	Sodium aluminium silicate	Calcium magnesium silicate
Hardness (Mohs)	6.5 to 7	6.0 to 6.5
Specific gravity	About 3.33	About 2.95
Refractive index	About 1.66	About 1.61
Toughness	Good, more brittle	Excellent, fibrous
Main sources	Myanmar, Guatemala	China, Canada, Russia, New Zealand
Typical price	Higher at equal quality	Lower, wider supply

How to Tell Them Apart Without a Lab

Colour will not help. Both stones occur in green, in white and in near-black, and both are dyed to imitate the most valuable shades.

Specific gravity is the quickest field clue. Jadeite sits near 3.33 and nephrite near 2.95, a difference you can feel as heft in the hand against a known stone.

A refractometer separates them cleanly. Jadeite reads about 1.66 on the scale, nephrite about 1.61. Very few shops own one, and fewer still will test a stone in front of you.

Hardness gives a rough answer. Jadeite at 6.5 to 7 scratches glass and mild steel. Nephrite at 6.0 to 6.5 is softer and will not match that scratch test reliably.

For anything above a few hundred dollars, a laboratory report is the only answer worth paying for. Home tests narrow the field; they do not settle it.

One warning about field kits. The scratch picks sold online are often calibrated for mineral specimens, not for finished jewellery. Used carelessly they leave a visible line on a polished surface, which lowers the value of a stone you were only trying to identify. Test on an inconspicuous edge, or do not test at all.

Hardness and Toughness and Why Both Matter

Jade scores unusually well on two properties that rarely appear together. It is hard enough to resist scratching and tough enough to resist fracture.

Hardness is resistance to abrasion. Toughness is resistance to crack growth. Diamond wins on hardness. Nephrite wins on toughness among common gem materials.

A thin nephrite bangle survives knocks that would shatter glass or emerald. Jadeite is harder but more brittle, and a sharp blow on an edge can take a chip out of it.

This is why jade is worn rather than stored. It handles keys, desks and door handles without dulling. It does not handle being dropped onto tile.

The practical rule is simple. Trust jade against daily friction, not against deliberate impact. Never test a bangle by tapping it on a hard surface.

Toughness also explains why thin bangles exist at all. A four millimetre nephrite band can survive everyday wear because the fibre structure spreads stress across the whole piece. The same band in jadeite would need more care, and a sharp knock near the rim is where most chips begin.

Where Jade Comes From

Fine jadeite comes mainly from Myanmar, from the Mogok and Hpakant areas in the north. The trade is large, loosely regulated and often conducted far from any laboratory.

Guatemala produces jadeite from the Motagua valley. The material tends to be darker and more mottled, and it has been mined since Maya times.

Nephrite is more widely distributed. Xinjiang in China yields the Hetian material that Chinese buyers have prized for centuries. British Columbia, Siberia and New Zealand also produce commercial volumes.

New Zealand treats its nephrite as a cultural asset. Pounamu belongs to Māori iwi, and its export and sale are restricted by law.

Origin adds value, but a finished bead rarely carries proof of it. Treat an origin claim as marketing until a laboratory confirms the material and, where relevant, the source.

Supply explains much of the price gap between the two species. Myanmar jadeite is mined from a limited number of concessions, and good rough is sold at auction to a small group of buyers. Nephrite comes from several countries with steady industrial output, so supply is steadier and prices are less volatile.

The Colour Range and What Drives It

Green is the colour most buyers picture, and the colour most often imitated. It is also the one with the widest internal range, from pale cabbage to near-black.

Imperial green comes from chromium. It is vivid, faintly blue-leaned and rare. A softer apple green can come from the same element at lower concentration.

Lavender jadeite takes its colour from manganese. White jade is close to pure jadeite with little iron. Black jade is dark from graphite or iron sulphide inclusions rather than from pigment.

Yellow and red jadeite are iron-stained and usually found near the weathered surface of a boulder. Both colours are stable in themselves, though dye is common in the market.

Colour is only half the story. Transparency and texture decide whether a green stone looks like jade or like painted stone. Our guide to Jade Colour Varieties covers each shade in detail.

Seeing the shades side by side is the fastest way to learn them. Our Jade Bracelets run from pale green to near-black, and the difference is easier to judge in a row than in a single photograph.

What Jade Has Meant to People

Jade has been worked in China for at least eight thousand years. Hongshan and Liangzhu sites produced ritual discs and tubes long before any organised jade trade existed.

Confucian writing tied the stone to virtue. Its hardness, its cool touch and its visible flaws all became metaphors for character, and the metaphor outlasted the empires that made it.

In Mesoamerica, jadeite meant breath and maize. Maya rulers wore it in life and had a bead placed in their mouths after death.

In New Zealand, nephrite carries a different weight. It is a taonga, a treasure with legal standing, and it is passed down rather than sold on an open market.

Three continents arrived at the same material without contact. The reasons were probably practical before they were spiritual: jade takes an edge, holds a polish and never corrodes. Our page on Jade Symbolism traces the beliefs that grew around it.

Treatments and the A, B and C Grades

The trade grades jade by treatment, using letters that describe what was done rather than how good the stone is.

Type A means no treatment beyond cutting and polishing. The colour, the transparency and the surface are natural.

Type B has been bleached to strip iron staining, then impregnated with polymer to restore lustre and mask fractures. The structure is altered, and the effect can fade with heat or time.

Type C is dyed. Type B plus C is bleached and then dyed, which is the most common combination in low-cost jewellery.

A treated stone can look better than an untreated one at the same price. The problem is never the treatment itself, it is a listing that omits it.

Reputable sellers name the type. If a listing says only natural jade, ask which of the three it means, and ask in writing.

How Jade Is Graded and Priced

Five factors set the price: colour, transparency, texture, size and workmanship. Origin adds a premium only when it can be documented.

In jadeite, transparency is called zhong and colour se. A small, highly transparent, evenly coloured piece outranks a large dull one, often by a wide margin.

Nephrite is valued on different terms. Even texture, an oil-like lustre and a warm white matter more than transparency. Hetian white is graded on purity and on the absence of visible structure.

Workmanship is the last multiplier. A bangle cut from a clean block with good proportion costs more than the same weight of rough sold as offcuts.

Band	What it buys	Typical price
Commercial	Even colour, slight cloudiness, machine-shaped beads	80 to 400 USD
Fine	Strong colour, good translucency, clean surface	400 to 2,000 USD
Top	Vivid even colour, high transparency, no visible flaw	2,000 USD and well above

These bands describe finished pieces, not rough. They also move with the Myanmar supply, which is the single largest influence on jadeite prices.

Two stones of the same size and weight can differ tenfold on colour alone. A bangle with even, vivid green and no visible cloud may sell for the price of twenty bangles in pale, patchy material. Buyers who compare by weight rather than by appearance almost always overpay.

Jade, Imitations and the Green-Stone Confusion

Most fake jade on the market is not fake stone. It is a different stone sold under a vague name.

Serpentine, aventurine, chrysoprase, prehnite and dyed quartzite all appear as new jade, Korean jade or mountain jade. None of them is jadeite or nephrite, and all of them are softer.

Glass and resin are easier to catch. Glass is too even, too cold to the touch and often carries round air bubbles. Resin feels warm and light.

Emerald is a different mineral altogether. It is beryl, singly crystallised, harder than jade and far more expensive per carat, which is why the two are rarely confused once seen side by side.

The tests that separate these materials are the same ones that separate jadeite from nephrite. Our guide to How to Spot a Fake walks through them in order.

How Jade Is Cut and Carved

Jade is cut with diamond, not with steel. Nothing softer will mark it, which is why the craft developed around abrasion rather than around blades.

A boulder is slabbed with a diamond saw, then shaped on a grinding wheel. Carving follows with diamond burrs and loose abrasive, worked wet to control dust and heat.

Polishing takes longer than cutting. The final lustre comes from progressively finer abrasive, never from a coating or a wax that will wash off.

Workmanship is judged on proportion, symmetry and how well the carver used the natural colour banding. A good carver works around an inclusion and turns it into part of the design.

This is the part of jade that photographs badly and reads well in the hand. Two pieces of the same weight can differ by a factor of five on carving alone.

Machine carving has changed the low end of the market. A computer-controlled burr can reproduce a motif hundreds of times, and the result is precise but flat. Hand carving costs more because the carver adapts each cut to the stone in front of them, and that adaptation is what collectors pay for.

How Jade Is Worn Today

A bangle is cut from a single block. A bead bracelet is drilled and strung from many small pieces. That difference drives cost, fit and risk.

A bangle needs a clean, large slab, so a good one is expensive by necessity. Beads can use smaller material, which is why a bead strand of decent colour costs a fraction of a bangle in the same shade.

Necklaces and rings follow the same logic. Pendants use flat slabs. Rings need solid, defect-free rough, and a jade ring with even colour is harder to make than it looks.

Men tend to choose wider beads and darker tones, often nephrite rather than jadeite. The reasoning is practical: a 10 mm bead in near-black shows wear less than a pale one.

Sizing matters more than most first-time buyers expect. A bangle has to pass over the knuckles, and the difference between a 56 mm and a 58 mm inner diameter is the difference between a piece worn daily and one left in a drawer. Measure the hand, not the wrist.

Choosing between the two main forms is mostly about how you live. Our guide to Bracelet versus Bangle sets out the trade-offs in plain terms.

Care and What Actually Damages Jade

Jade is durable, not indestructible. The threats are chemical, thermal and mechanical, in that order of frequency.

Acids, bleach and chlorinated water attack the polish. On a treated stone they also attack the polymer filler, which is why a type B piece must never go near a cleaning agent.

Ultrasonic and steam cleaners are worse than most owners expect. Vibration can open a hairline fracture that was invisible before the cleaning.

Clean with lukewarm water, a soft brush and a dry cloth. Store each piece separately, because harder stones in the same box will scratch jade over years.

Heat is the third risk. A bangle left on a windowsill in summer or beside a hob can crack from thermal shock, especially if it is cold when the heat arrives.

Our full guide to Care and Cleaning covers storage, travel and what to do when a bead cracks.

Restringing is the one repair worth planning for. Silk and elastic both stretch, and a strand that hangs loose puts extra strain on the drill holes. Have a bead bracelet restrung every few years, and ask the jeweller to check the holes for cracks while the string is out.

Buying a First Piece

Buy the report before the stone once the price is meaningful. A laboratory card should name the species, the treatment status and the weight.

A card that says only natural jade tells you very little. It may mean untreated jadeite, untreated nephrite or a stone that has been bleached and filled without disclosure.

Ask for daylight photographs and a short video in indirect sun. Shop lighting is designed to flatter colour, and it flatters dyed stones most of all.

Check the return window before you pay. Jade is genuinely hard to judge from images, and a seller who refuses returns is telling you something about their confidence.

Start with a bead strand rather than a bangle. It is cheaper, easier to size and it teaches you what the stone looks like in daylight before you commit to a large purchase.

Our Buying Jade with Confidence checklist runs through the questions worth asking before payment.

Why Jade Still Endures

Jade survives because it rewards patience. Colour deepens slightly with wear, surfaces polish rather than dull, and a piece bought cheaply can look better in ten years than it does today.

It is also one of the few gem materials with a cultural record longer than any brand. A jade bangle has been a plausible object of desire in China for more than three thousand years.

That makes it a strange purchase. It is an ornament, a material study and a piece of history at the same time, and the three do not always point at the same stone.

For a first buy, decide which of the three you actually want. The answer changes the colour, the form and the budget, and it is worth knowing before you compare listings.

The stone is also easy to over-think. Most people end up wearing the same piece for years, and the qualities that matter in daily use are ordinary ones: a colour they still like in grey weather, a weight that does not annoy them, and a form that survives their actual routine.

From here you can read the species comparison, the colour guide or the care notes. Each path leads back to the same question: what is this stone, really.

Frequently Asked Questions

Is jade harder than steel?

Jadeite sits at 6.5 to 7 on the Mohs scale, and mild steel sits around 5 to 6.5. A sharp jade edge will scratch ordinary steel and glass. Nephrite, at 6.0 to 6.5, is softer and less reliable in a scratch test.

Can jade get wet?

Brief contact with lukewarm water is safe and is the standard way to clean jade. Prolonged soaking, chlorinated water, acids and detergents are not. A treated type B stone is the most vulnerable, because water and chemicals can attack the polymer filler.

Is jade always green?

No. Jadeite occurs in white, lavender, yellow, red, black and blue as well as green. Nephrite runs from spinach green through to near-white and to black. Green is simply the colour the market rewards most, so it dominates at retail.

Is jade a good investment?

Only at the top of the market. Auction-grade jadeite with certified colour and transparency has held value. Commercial bead strands do not appreciate, and jade is an illiquid asset with high spreads. Buy it to wear, not to flip.

Natural stone varies from piece to piece. Photographs are indicative, and colour may differ on your screen. Any reference to traditional beliefs, luck or healing reflects cultural practice, not established scientific fact. Certification claims are the responsibility of the issuing laboratory.
