Jadeite vs Nephrite vs Hetian Jade: The Real Differences
Jadeite vs Nephrite
vs Hetian Jade
"Jade" is a nickname shared by two different minerals — and a lot of confusion. Here's what jadeite, nephrite and Hetian jade actually are, and what a certificate should tell you.
"Jade" is an
umbrella
The single fact that clears up most confusion: jade isn't one material.
Since the 19th century, gemmologists have known that stones sold as "jade" are actually one of two distinct minerals - jadeite or nephrite. Both are genuinely jade in the cultural sense; they simply have different chemistry, and telling them apart usually needs a lab.
How they
differ
The practical differences:
| Trait | Jadeite | Nephrite |
|---|---|---|
| Mineral | Pyroxene | Amphibole |
| Rarity | Rarer | More common |
| Colour | Vivid greens, lavender, more | Softer greens, cream, grey, black |
| Translucency | Can be highly translucent | Usually more opaque, waxy |
| Toughness | Very tough | Exceptionally tough |
Where Hetian
jade fits
Hetian jade (also spelled Khotan) is a nephrite, historically mined near Hetian in Xinjiang, China, and treasured for its pale, luminous "mutton-fat" white. It sits inside the nephrite family - so a label like "Hetian jadeite" is a contradiction and a red flag.
Hetian is prized in Chinese tradition much as vivid green jadeite is prized in others; different stones, different ideals of beauty.
"Grade A" is about
treatment
For jadeite, the A/B/C system describes treatment, not quality. Type A is natural jadeite with no chemical alteration beyond a surface wax. Type B has been bleached and impregnated with polymer to improve clarity. Type C has been dyed to add colour.
So "Grade A" tells you a stone is untreated - not that it's high quality or valuable. Those are separate judgements.
Reading a
certificate
Because eye and hand can't reliably separate jadeite from nephrite - or natural from treated - a report from a gemmological laboratory is what actually settles it. Look for the mineral named (jadeite or nephrite), the treatment status (e.g. Type A / natural), and the issuing lab.
Origin (such as Hetian or Burmese) is harder to prove and is often stated as an opinion rather than a fact.
Common
mislabels
A few phrases should make you ask questions: mixing Hetian with jadeite, calling any green stone "jade" without naming the mineral, or claiming "Grade A" with no certificate. None of these are automatically dishonest - but each is worth a plain question before you buy.
The healthiest habit is simple: ask what mineral it is, whether it's treated, and to see the paperwork.

Frequently asked
What is the difference between jadeite and nephrite?
They are two different minerals that share the name jade. Jadeite is a pyroxene mineral, generally rarer, and can reach vivid emerald greens. Nephrite is an amphibole mineral, exceptionally tough, and tends toward softer greens, creams and greys. Both are genuine jade.
Is jadeite or nephrite better?
Neither is simply better. Jadeite is prized for vivid colour and translucency and is generally more valuable, while nephrite is prized for its toughness and smooth, calm appearance. The right one depends on the look and story you want, not a ranking.
Is Hetian jade jadeite or nephrite?
Hetian jade is a nephrite, historically from the Hetian (Khotan) region of Xinjiang, China, and famous for pale "mutton-fat" white tones. Calling something "Hetian jadeite" mixes two categories, which is a common labelling error to watch for.
What does Grade A jade mean?
For jadeite, "Type A" or "Grade A" means natural jadeite with no chemical treatment beyond a surface wax. Type B has been bleached and polymer-impregnated; Type C has been dyed. The grade describes treatment, not quality, and should be backed by a certificate.
