Jadeite vs Nephrite: How the Two Jades Differ

Two Stones, One Name

The word jade entered English through Spanish and French, and it arrived already confused. Early traders applied it to any green stone that took a polish, including serpentine and quartz.

Modern gemmology split the name in two. Jadeite is the harder, rarer material from Myanmar and Guatemala. Nephrite is the tougher material that China, Canada and New Zealand have supplied for centuries.

Both are aggregates. Neither is a single crystal, which is why neither cleaves like emerald or quartz. The difference is what the aggregate is made of and how it holds together.

Everything that follows, from price to care, comes back to what jade actually is at the mineral level.

What Jadeite Is

Jadeite is a sodium aluminium silicate in the pyroxene group. Its ideal formula is NaAlSi2O6, though natural stone carries calcium, magnesium and iron in place of some sodium.

It forms in subduction zones, where oceanic crust is forced under a continental plate. The pressure is high and the temperature is moderate, and the crystals grow tightly packed rather than randomly.

The conditions are narrow, which is why the stone appears in so few places. Our guide to How Jade Forms walks through the geology, from fluid chemistry to the boulders that reach the market.

That packing gives jadeite its glassy lustre and its fine grain. Under a loupe, a good piece shows a sugary texture with individual crystals barely resolvable.

Pure jadeite is white. Colour comes from trace elements: chromium and vanadium produce green, manganese produces lavender, and iron produces the yellow and red tones found near the surface of a boulder.

Jadeite is the rarer of the two species and the one that carries the auction prices. Almost all fine material still comes from northern Myanmar.

What Nephrite Is

Nephrite is an amphibole, a solid solution between tremolite and actinolite. Its formula runs roughly Ca2(Mg,Fe)5Si8O22(OH)2, with iron content deciding how dark the stone looks.

It grows where hot, silica-rich fluids react with serpentinite. The result is a mass of interlocking fibres, each too fine to see without magnification.

Those fibres are the reason nephrite feels creamy rather than glassy. They scatter light softly and they blunt the tip of a growing crack, which is why nephrite is the tougher material.

Colour runs from spinach green through sage and celadon to near-white. The white material from Xinjiang, sold as Hetian jade, has been the reference standard in China for centuries.

Nephrite is not a lesser stone. It is a different stone, and in Chinese culture it is the older and more culturally loaded one.

Side-by-Side Comparison

The table below condenses the physical and commercial differences. The figures are standard reference values, not measurements of any single piece.

Property	Jadeite	Nephrite
Group	Pyroxene	Amphibole
Formula	NaAlSi2O6	Ca2(Mg,Fe)5Si8O22(OH)2
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	Excellent
Lustre	Glassy to greasy	Greasy, waxy
Main sources	Myanmar, Guatemala	China, Canada, Russia, New Zealand
Price at equal quality	Higher	Lower

Two lines in that table matter more than the rest. Specific gravity separates the species in the hand, and toughness explains why nephrite bangles survive knocks that would chip jadeite.

Hardness and Toughness

Jadeite is the harder stone. At 6.5 to 7 on the Mohs scale it scratches glass and mild steel, and it holds a polish longer than most gem materials.

Nephrite sits at 6.0 to 6.5, softer by a small margin. In a scratch test the gap is narrow enough that a careless hand can leave a mark on either stone.

Toughness reverses the ranking. Nephrite’s fibre structure distributes stress across the whole piece, so a thin bangle resists impact far better than the same shape in jadeite.

For a bracelet, this is the practical difference. A nephrite bangle can be cut thinner and worn daily with less risk. A jadeite bangle of the same thickness needs more care around hard edges and tiled floors.

Neither stone is suitable for deliberate impact. Toughness protects against accidents, not against being dropped on purpose.

Colour Ranges in Each Species

Green is the colour both species are known for, and both produce it for different reasons.

In jadeite, chromium gives the vivid imperial green and vanadium gives a softer, slightly bluer green. Iron produces the duller olive tones, which sit at the bottom of the price range.

Nephrite green comes from iron in the amphibole structure. It tends toward spinach, sage and celadon, and it rarely reaches the brightness of fine jadeite.

Lavender is effectively a jadeite colour. So are the bright yellow and red tones that come from iron staining near a boulder’s surface.

Nephrite covers white, green and black, with brown tones from weathering. The even, warm white of Hetian material is its own category, graded on purity rather than on saturation.

For a fuller treatment of each shade, see our guide to Jade Colour Varieties.

Colour is also the quickest way to see the species gap in person. Our Jade Bracelets run mostly nephrite in green and white, which makes a useful baseline before you compare a jadeite piece.

Specific Gravity and Refractive Index

Two measurements do most of the work in a gem lab, and both are quick.

Specific gravity is the ratio of a stone’s weight to the weight of the same volume of water. Jadeite comes in near 3.33, nephrite near 2.95, a gap wide enough to feel in the hand once you have handled a known piece.

Refractive index measures how much light bends as it enters the stone. Jadeite reads about 1.66, nephrite about 1.61. The reading is taken on a polished surface, usually a flat spot or a cabochon.

Neither figure is unique to jade. Aventurine, serpentine and some quartzites fall in similar ranges, which is why the readings are a first filter rather than a verdict.

The refractive index matters most when a stone is opaque and colour is ambiguous. A quick reading separates jadeite from nephrite even when both are dark green and both look waxy.

How Laboratories Separate Them

A proper report goes beyond two numbers. It identifies the species, records the treatment status and notes any polymer, dye or coating.

Fourier-transform infrared spectroscopy detects polymer and resin in the structure. It is the standard method for spotting a type B stone, and it works even when the filler is colourless.

Raman spectroscopy identifies the mineral itself, which matters when a stone is too small or too included for a clean refractive index reading.

X-ray fluorescence can flag unusual trace elements, including some dyes. It does not identify species on its own, so labs use it alongside the other methods.

For a buyer, the practical point is that a card saying natural jade is not enough. The report should name jadeite or nephrite, and it should state whether treatment was detected.

Price and Market Differences

Fine jadeite is expensive in a way that surprises buyers who know only beads. Auction-grade bangles with even imperial green have sold for more than most diamonds of the same weight.

The gap comes from supply. Jadeite of good colour comes from a small number of concessions in Myanmar, and the rough is sold at auction to a narrow group of buyers.

Nephrite is steadier. Canada, Russia, China and New Zealand all produce commercial volumes, so a good white or green bangle stays within reach of ordinary buyers.

Where the two overlap is the bead market. A strand of mid-green nephrite beads can cost a tenth of a jadeite strand of similar colour, and most buyers cannot tell them apart across a room.

That overlap is exactly where misdescription happens. A listing that says only jade can hide a tenfold price difference inside the same photograph.

Where Each Comes From

Jadeite is concentrated in a handful of places. Myanmar supplies the great majority of fine material, from the Mogok and Hpakant regions in the north.

Guatemala produces jadeite from the Motagua valley, generally darker and more mottled. Japan and Russia produce small amounts, rarely in jewellery grades.

Nephrite is widespread by comparison. Xinjiang in China yields Hetian material. British Columbia in Canada supplies large volumes of green nephrite. Siberia, New Zealand and Australia all produce commercial stone.

Origin adds value only when it can be proven, and proof below auction level is unusual. A seller who claims Burmese origin without a report is offering a story, not a fact.

New Zealand is a special case. Its nephrite, called pounamu, is treated as a cultural treasure and its sale is restricted. That status has nothing to do with gem quality and everything to do with law.

For the deposits themselves, including what each region produces and how it is graded, see Where Jade Comes From.

How Treatments Differ

Both species can be treated, but the methods and the risks are not the same.

Jadeite is routinely bleached and polymer-impregnated to remove iron staining and improve transparency. The trade calls this type B. Dyeing is type C, and the combination is type B plus C.

Nephrite is treated less often because it is already affordable in good colour. It is sometimes waxed or oiled to improve lustre, which is a surface treatment and usually reversible.

The distinction matters for care. A polymer-filled jadeite stone can be damaged by heat, steam or solvent, while an untreated nephrite bangle will tolerate normal cleaning.

Our guide to treatments explains the A, B and C Grade system in detail, including what each method does to the stone.

What This Means When Buying

Start with the species, not the colour. A pale, even nephrite bangle and a pale, even jadeite bangle can look identical in a listing and differ by a factor of ten in price.

Ask for the specific name. Jadeite and nephrite are different words and both should appear on a report. If the seller uses only jade, ask which one, and ask in writing.

Check the treatment status next. An untreated piece holds value better and survives cleaning with less fuss.

Then judge colour in daylight. Photographs taken under warm light make green look richer, and they make dyed stones look natural.

Finally, match the stone to the form. A thin bangle in nephrite is a reasonable daily piece. The same dimensions in jadeite will need more careful handling.

Which One Should You Choose

For a first piece worn daily, nephrite is the easier answer. It is tougher, cheaper at equal appearance and it tolerates ordinary knocks.

For colour, jadeite wins. Imperial green, lavender and the bright yellow tones have no real nephrite equivalent, and a jadeite piece holds its appearance better under strong light.

For cultural intent, the answer depends on which tradition you are drawing from. Chinese buyers often want Hetian nephrite for its association with virtue. Buyers chasing the auction look want jadeite.

For resale, only top-grade jadeite has a functioning market. Nephrite resells slowly and usually at a discount, so buy it to wear.

If you are undecided, buy a bead strand first. It costs less than a bangle and it teaches you how the stone looks in your own daylight.

Common Misconceptions

The first is that jade is a single material. It is two, and the difference is larger than the difference between many unrelated gems.

The second is that green means jadeite. Plenty of green nephrite exists, and plenty of green serpentine is sold as jade. The same confusion runs the other way with emerald, and Jade versus Emerald separates the two by mineral, hardness and price.

The third is that harder means better. Jadeite is harder, nephrite is tougher, and for a bangle toughness is the property that keeps it intact.

The fourth is that an old piece must be valuable. Age affects cultural interest, not mineral quality, and many antique-looking pieces are recent carvings in treated stone.

The fifth is that a certificate guarantees beauty. A report confirms species and treatment. It says nothing about whether the colour suits you.

If you want to test a stone at home, our guide to How to Spot a Fake sets out what actually works and what damages the piece.

Frequently Asked Questions

Is jadeite more valuable than nephrite?

At equal visual quality, yes. Fine jadeite with vivid even colour and high transparency trades far above nephrite. Nephrite is affordable in good colour, so the two only compete at the low end, where beads can look similar and prices differ by ten times.

Can you tell jadeite from nephrite by looking?

Not reliably. Jadeite has a glassier lustre and a finer grain, nephrite looks waxy and fibrous. Colour overlaps in both species, and photographs remove the cues that survive in the hand. A refractive index reading or a lab report settles it.

Which is better for a bracelet?

Nephrite is tougher, so a thin bangle survives knocks better. Jadeite is harder and holds a gloss longer, but it chips more readily on an edge. For daily wear, nephrite is the lower-risk choice. For colour, jadeite is the only option.

Is Hetian jade jadeite?

No. Hetian jade is nephrite from Xinjiang in China. The name refers to a source and a tradition, not to the species. Chinese buyers often prefer it precisely because it is nephrite, which has the longer cultural record.

Natural stone varies from piece to piece. Photographs are indicative, and colour may differ on your screen. Physical values are standard reference ranges, not measurements of a specific item. Any reference to traditional beliefs reflects cultural practice, not established scientific fact.
