How to Tell If Hetian Jade Is Real: A Buyer's Guide (2026)
Share
Quick answer: Real Hetian jade is nephrite. It is dense (around 2.95 g/cm3), it is tough (Mohs 6 to 6.5), and it has a soft, greasy luster over a fibrous, interlocking grain. Pick one up and it feels cool, then warms slowly in your hand. Home checks will catch the crude fakes. They will not settle the question for good. For that you need a report from an independent gemological lab, which is why you should only buy from a seller who provides third-party certification.
What Hetian jade actually means
Hetian jade (also spelled Hotan jade, 和田玉) is nephrite. It takes its name from the Hotan region of Xinjiang, China, where the best material has come out of the rivers and mountains for over 5,000 years. The gem trade recognizes only two minerals as true jade. Nephrite is one. The other is jadeite, the Burmese 'feicui'.
'Real' Hetian jade can mean two separate things, and it pays to keep them apart.
- Genuine nephrite, as opposed to glass, serpentine, marble, or a plastic imitation.
- Genuine Xinjiang-Hotan origin, as opposed to nephrite from Russia, Qinghai, or Korea. That is the same mineral, just a different source.
Most home tests only answer the first question. The second one takes a gemological lab and an experienced eye.
7 ways to tell real Hetian jade from a fake at home
No single test settles it. Run a few of them, and read the results as warning signs rather than verdicts.
- Heft (density). Nephrite is dense, with a specific gravity near 2.95. Hold a real piece and it feels noticeably heavier than a same-sized lump of glass or plastic.
- Hardness. Nephrite sits at Mohs 6 to 6.5, harder than a steel blade (about 5.5) and harder than window glass. It shrugs off scratches, whereas a soft fake like serpentine (Mohs 2.5 to 5.5) marks up easily. One warning: never scratch-test a finished piece you actually care about, because it can leave a mark.
- Luster and texture. Good Hetian nephrite has a soft, greasy, almost oily luster. It will not show the hard glassy glare of glass or the dull waxiness of serpentine. Hold a fine piece to the light and you can see a felt-like, fibrous structure (collectors call it 'cotton'). What you should never see is air bubbles.
- Temperature. Jade feels cool and warms slowly. It is a useful clue but a weak one, since glass and plenty of other stones feel cool too. Do not lean on it by itself.
- Sound. Tap two pieces together gently, or tap a bead with a coin. Real nephrite gives a clear, crisp, almost metallic ring. Glass and resin answer with a dull, plasticky thud.
- Light and color. Under a bright light, natural nephrite glows softly and evenly. Color that pools inside the cracks points to dye. Bubbles point to glass.
- Natural imperfections. Real jade nearly always carries a little natural variation: a faint line here, a subtle shift in color, the odd tiny inclusion. A 'jade' that is flawless, perfectly uniform, and suspiciously cheap is waving a red flag at you.
Important: these checks weed out the obvious imitations, but they cannot grade quality and they cannot confirm origin. For that, you need certification.
Common Hetian jade fakes and imitations
| Imitation | What it really is | How to spot it |
|---|---|---|
| Glass | Molded glass, often dyed | Air bubbles, color that looks too perfect, warms quickly, dull ring |
| Serpentine (Xiuyan / 'new jade') | A softer green stone | Scratches easily (Mohs 2.5 to 5.5), waxy look, feels lighter |
| Dyed or treated nephrite (B/C grade) | Real nephrite, color-enhanced or filled | Dye pooling in cracks, unnaturally even color, caught by a lab report |
| Resin or plastic | Cast polymer | Very light, warm to the touch, may smell when warmed |
| 'Afghan jade' (marble/calcite) | Banded carbonate stone | Softer, often banded, reacts to acid |
| Other-origin nephrite | Genuine nephrite from Russia, Qinghai, or Korea | Real jade, but not Xinjiang Hotan; only a lab and an expert eye can tell |
The only definitive test: third-party certification
The best imitations are made to fool the eye, so the dependable way to confirm Hetian jade is an independent gemological report. A lab measures the refractive index and the specific gravity, reads the internal structure, confirms the material is nephrite, and flags any dyeing or filling.
- In China, the authority is the NGTC (National Gemstone Testing Center). Internationally, accredited labs such as the GIA test nephrite as well.
- A proper certificate names the material (nephrite / 和田玉), says whether it is natural or treated, lists the weight, and carries a unique report number and QR code that you can check on the lab's official website.
At Unique Jade, every piece ships with a third-party certificate of authenticity, so you know exactly what you are buying. We also back every order with 7-day, no-questions-asked returns.
What determines Hetian jade's value
Once you know a piece is genuine, what you pay comes down to quality, not authenticity alone. Here is what moves the price.
- Color. Pure, even white is the most coveted of all, the famous 'mutton-fat jade' (羊脂玉) that fetches the top prices. Green (Bi jade, 碧玉), sugar, and black (Mo jade, 墨玉) are prized too.
- Texture and oiliness. The finer and denser the grain, and the more it seems to glow from within, the higher the grade.
- Purity. The fewer cracks, impurities, and patches of 'cotton', the more a piece is worth.
- Material type. River-tumbled seed material (籽料) from Xinjiang is the rarest and dearest. Mountain material (山料) is more common and easier on the wallet.
- Skin color (皮色). Natural skin tones on seed material, when a carver uses them well, can add real value.
- Craftsmanship. The artistry of the carving, and the name behind it, can matter as much as the stone.
How to buy Hetian jade online without getting burned
- Insist on a third-party certificate, then verify its number on the issuing lab's website.
- Buy only from sellers with a clear return policy.
- Look for real photos or video, a stated weight and dimensions, and honest natural variation.
- Treat 'mutton-fat' white at a bargain price with real suspicion. When it looks too good to be true, it usually is.
- Make sure the price tracks the quality factors above, not the size of the piece.

Frequently asked questions
Is Hetian jade real jade?
Yes. Hetian jade is nephrite, one of the two minerals officially recognized as jade (the other is jadeite). China has treasured it for over 5,000 years.
Does real jade scratch glass?
Genuine Hetian nephrite (Mohs 6 to 6.5) is harder than glass and will scratch it. The trouble is that imitations like jadeite or quartz scratch glass too, and the test itself can damage your piece. Treat it as a hint, not proof, and rely on certification instead.
Can the cold-to-the-touch test prove jade is real?
No. Jade does feel cool and warm slowly, but so do glass and many other stones. It is a weak indicator and never the final word.
Is Hetian jade a good investment?
Fine certified Hetian jade, high-grade white seed material above all, is widely collected and has appreciated over the years. Value leans heavily on quality, origin, and a credible certificate, so enjoy an everyday piece as jewelry first and treat any investment upside as a bonus.
How do I verify a jade certificate?
Reputable reports, including those from the NGTC, carry a unique number and often a QR code. Type in the number or scan the code on the issuing lab's official website to confirm the report matches the item in your hand.
What is the difference between Hetian jade and jadeite (feicui)?
They are two different minerals. Hetian jade is nephrite, the softer one, with a greasy luster and a fibrous grain. Jadeite is harder and glassier, and it includes Burmese feicui. Both count as genuine jade.
