Real vs. Fake Jade: How to Tell Genuine Jade from Imitations
Jade is one of the most valuable — and most imitated — stones in the world, which makes the market a minefield of treatments and outright fakes. To make it trickier, “jade” is actually two different minerals, and genuine jade is often bleached, resin-filled, or dyed. This guide explains how to tell natural jade from treated and imitation material, with the practical tells you can use before you buy.
At Gems Lore, we think understanding jade makes it far more rewarding to own. Here’s the real story.
Real vs. Fake Jade at a Glance
- Type A jade: natural, untreated jade (only surface wax) — genuine and the most valuable.
- Type B jade: real jade bleached and resin-impregnated to improve look — real material, but treated and less valuable.
- Type C jade: dyed jade — color artificially added, and it can fade over time.
- Outright fakes: dyed serpentine, quartz, glass, and other stones sold as jade.
- The key question: which type, and is it even jade at all? Value varies enormously.
First: “Jade” Is Two Minerals
Before real-vs-fake, it helps to know that genuine jade comes in two forms: jadeite (rarer, harder, and generally more valuable — the source of prized “imperial” green jade) and nephrite (more common and exceptionally tough, long carved in China and beyond). Both are true jade. When people talk about expensive treated jade, they usually mean jadeite. We cover the full distinction in our jadeite vs. nephrite guide, and the stone’s meaning in our jade meaning guide.
The Jade Grading System: Type A, B, and C
Unlike most stones, jade has a well-known treatment grading system worth memorizing:
Type A — Natural
Type A jade is natural, untreated jadeite, with nothing done but a traditional surface wax. Its color and structure are entirely genuine. This is the real, valuable jade collectors want — and the only kind that fully holds its worth.
Type B — Bleached and Resin-Impregnated
Type B jade is real jade that’s been bleached with acid to remove brown or grey tones, then impregnated with polymer resin to restore hardness and clarity. It’s still genuine jade material, but the treatment is significant, the value is far lower, and the resin can degrade or yellow over time. Under a loupe, Type B often shows an etched, “orange peel” surface texture.
Type C — Dyed
Type C jade has had color added by dye — often to fake the prized green or lavender. The dye can fade with time and sunlight, and under magnification it typically pools in the tiny cracks and between grains. Jade that’s both bleached-and-impregnated and dyed is called Type B+C.

Common Jade Imitations
Beyond treated real jade, many other stones are sold as jade entirely:
- Dyed serpentine (“new jade,” “Korean jade,” “olive jade”) — a softer green stone often passed off as jade.
- Dyed quartz (“Malaysia jade,” “Australian jade”) — quartz dyed vivid green.
- Dyed howlite or magnesite — white stones dyed to imitate jade or turquoise.
- Aventurine and chrysoprase — green stones sometimes mislabeled as jade.
- Glass and plastic — cheap molded imitations, often too flawless and full of bubbles.
Our how to spot fake crystals guide covers the general techniques for catching these.
How to Tell Real Jade from Fakes
A few reliable at-home tells help separate genuine jade from imitations:
- Temperature: real jade is dense and stays cool, warming slowly in the hand. Glass and plastic warm up quickly and feel light.
- Heft: jade is notably dense and heavy for its size. A piece that feels light for its bulk is likely glass, plastic, or a lighter stone.
- The sound test: gently tapping two genuine jade pieces (or a jade bead against another) produces a clear, resonant, musical “clink.” Glass and plastic sound dull and flat.
- Luster: jade has a smooth, slightly greasy or soapy sheen rather than a glassy shine.
- Dye in cracks: under a loupe, dyed material (Type C or fakes) shows color concentrated in fractures and between grains rather than evenly through the stone.
- Air bubbles: trapped round bubbles under magnification mean glass, never jade.
- Hardness: jadeite is about 6.5–7 and nephrite about 6–6.5, so genuine jade resists scratching — but avoid scratch-testing carved or valuable pieces. See our gemstone hardness chart for context.
- Price: fine natural Type A jade is genuinely expensive. A large, flawless, vivid, cheap “jade” piece is treated or fake.
No single test is proof on its own, but together they’re a strong guide.
A Quick At-Home Approach
You can catch most obvious fakes without a lab:
- Feel it — note whether it’s cool and dense (jade) or warm and light (glass/plastic).
- Listen — tap gently for that clear, resonant jade clink versus a dull click.
- Look with a loupe for dye pooling in cracks and for air bubbles.
- Check the price against the real value of natural jade — bargains are a red flag.
- Ask the seller directly whether it’s Type A, B, or C, and jadeite or nephrite.
Remember these confirm obvious fakes but can’t always prove a piece is untreated Type A — that often needs lab testing.
Does It Actually Matter?
Whether the difference matters depends on you. If you love jade for its color and feel, treated jade is still (usually) genuine jade material, and even serpentine “new jade” is a real stone many happily wear. What matters is honesty and price: Type A jade commands a premium, and you shouldn’t pay Type A prices for Type B, C, or an imitation. For collectors and investors, Type A provenance is everything; for someone who just wants a pretty green pendant, a treated or alternative stone at a fair price may be perfect. There’s no single right choice — only an informed one.
Jade Names and Labels to Know
The jade trade is full of misleading names. A quick decoder:
- “Type A jade”: natural, untreated — what to look for, ideally with certification.
- “Type B” / “Type C” jade: treated (resin-impregnated and/or dyed) genuine jade, worth far less.
- “New jade,” “olive jade,” “Korean jade”: usually serpentine, not true jade.
- “Malaysia jade,” “Australian jade”: typically dyed quartz.
- “Mutton fat jade”: a genuine, prized creamy-white nephrite (a real term, not a fake).
- “Imperial jade”: top-grade, intensely green natural jadeite — real and very valuable.
If a label just says “jade” with no type or mineral and the piece is vivid and cheap, assume treatment or imitation until proven otherwise.
How to Buy Real Jade
If you want genuine jade, a few tips help:
- Ask for the type and mineral — reputable sellers will tell you Type A/B/C and jadeite or nephrite.
- Get certification for any significant purchase; a gem lab can confirm Type A and identify treatments.
- Be realistic about price — fine natural jade is costly, so treat cheap “jade” with suspicion.
- Look for natural variation rather than flat, uniform, candy-green perfection.
- Buy from reputable sources. See our how to buy gemstones online guide for choosing trustworthy sellers.
An Honest Word
Jade is a masterclass in crystal honesty: “fake” spans everything from resin-filled real jade to dyed serpentine, and the truth is layered. Much jade is treated, which is acceptable when disclosed and fairly priced — the real problems are Type B/C sold as Type A, and imitations sold as jade at all. Home methods give strong clues, but for a valuable piece, buy from someone you trust and get lab certification. Above all, buy what you love at a fair price for what it truly is.
Frequently Asked Questions
How can I tell if jade is real?
Check that it’s cool and dense, listen for the clear resonant “clink” of genuine jade, and look under a loupe for dye pooling in cracks or air bubbles (signs of dye or glass). Real jade also has a smooth, greasy luster and resists scratching, while fine natural jade is never cheap.
What is Type A, B, and C jade?
Type A is natural, untreated jade (only waxed). Type B is real jade bleached and resin-impregnated. Type C is dyed jade. Type A is the most valuable; B and C are treated and worth far less, and dye can fade over time.
Is treated jade still real jade?
Type B and C jade is usually still genuine jade material, but significantly altered by bleaching, resin, or dye. It’s real jade, just treated — and shouldn’t be confused with outright imitations like dyed serpentine or glass, or priced like natural Type A.
What stones are sold as fake jade?
Common imitations include dyed serpentine (“new jade”), dyed quartz (“Malaysia jade”), dyed howlite or magnesite, aventurine, chrysoprase, glass, and plastic — all sold as jade despite not being true jadeite or nephrite.
Does the jade “clink” test really work?
Tapping genuine jade pieces produces a clear, resonant, musical tone, while glass and plastic sound dull and flat. It’s a helpful clue, especially for beads and bangles, though it works best alongside temperature, density, and loupe checks.
Where to Go From Here
The jade story is really about buying wisely: know the type (A, B, or C), know the mineral (jadeite or nephrite), pay a fair price for what it is, and enjoy it. Watch for dyed serpentine and Type B/C sold as natural, and lean on the temperature, clink, and loupe tests to protect yourself.
