Dyed and resin-treated jade is everywhere, and to the naked eye, a lot of it looks convincing. If you're holding a jade bracelet and wondering whether it's genuine, it's a sensible thing to ask. This guide walks through the checks you can actually do at home, and is upfront about what they can and can't tell you.
Key Takeaways
- "Fake" jade usually means treated jade, not the wrong stone. Jadeite and nephrite are both genuine jade.
- Type A (natural, untreated) is the only category that holds its value and colour over time. Types B and Type C are treated to varying degrees.
- Simple checks like temperature, weight, sound and visual inspection can raise or lower your confidence, but none of them can prove authenticity on their own.
- The only reliable guarantee comes from lab certification or a jeweller who backs their Type A claim with a written guarantee.
What 'Real' Jade Actually Means
Before anything else, it helps to clear up a common mix-up.
Jadeite and nephrite are both genuine jade, so "fake" rarely means someone sold you the wrong mineral.
What it usually means is that the jade has been chemically treated to look better than it naturally is, whether by bleaching, dyeing, or filling with polymer resin. The real question isn't "is this jade or not jade", it's "has this jade been treated, and was I told about it?".
Type A vs Type B vs Type C Jade

The jade trade classifies treatment using a simple A, B, C system.
Type A jade is natural and untreated, aside from a traditional wax polish. This is the only category considered genuine, unaltered jade by collectors and reputable jewellers, and it's the standard we hold every piece at The Jade Galleria to.
Type B jade has been chemically bleached to remove impurities, then injected with polymer resin to improve its clarity and stability. It's still natural jade, but the acid bleaching weakens the stone's structure, and the resin filling tends to degrade over the years, causing the colour to dull or yellow.
Type C jade has been dyed to enhance or completely change its colour, often on pale, unremarkable material to imitate more desirable shades. Type C is the most common source of "too good to be true" pricing, since dye is far cheaper than sourcing naturally saturated jade.
Only Type A holds its value, colour and durability over time, which is why it's worth learning to spot the difference.
Quick At-Home Checks (and Their Limits)
Before trying any of these, it's worth being honest about what they can do. Skilled treatments, particularly modern polymer filling, can pass most home tests. Treat the results below as signals worth paying attention to, not a verdict.
The Temperature (Cold) Test
Real jade feels cool to the touch and takes a while to warm up against your skin, usually a minute or more. Glass and plastic imitations warm up almost immediately. Hold the bracelet in your palm for 30 to 60 seconds and pay attention to how quickly it matches your body heat. This is only suggestive on its own, as some treated jade and other cool-to-touch stones can feel similar at first contact.
Weight and Density
Genuine jade is dense and feels heavier than its size suggests. Hold the bracelet in your hand and compare it mentally to how a similarly sized piece of glass or plastic would feel, noticeably lighter. This works best when you have something to compare against, such as a piece you already know is real.
The Sound Test (Beaded Bracelets)
For beaded jade bracelets, gently tap two beads together, or tap the bracelet lightly with a metal object such as a ring or coin. Genuine jade beads produce a clear, resonant, almost musical tone. Treated jade, glass, or resin beads tend to sound duller and flatter by comparison. Avoid tapping too hard, particularly on a mounted or set piece, as this test carries a small risk of chipping the stone.
Visual Check Under Light
Hold the bracelet up to natural light and look closely at the internal texture. Genuine jade typically shows a subtle, fibrous or slightly mottled internal structure, with gentle variation in colour rather than perfect uniformity.
Warning signs include dye that appears to pool or concentrate in cracks and surface fissures, tiny air bubbles (a sign of glass), or a colour that looks flat and unnaturally even throughout.
Why At-Home Tests Aren't Enough: Type A and Certification

Here's the honest part. None of the checks above, on their own or combined, can definitively prove a piece is Type A natural jade. Well-executed treatments are specifically designed to pass casual inspection, and laboratory testing is the only reliable way to detect jadeite treatment, since bleaching and polymer impregnation are often invisible even to experienced eyes without proper equipment.
In practice, that means the only genuine guarantee comes from either independent gemological lab testing or from buying from a jeweller willing to put their reputation behind what they're selling.
At The Jade Galleria, every piece is natural Type A jadeite, and we back that with our own authenticity guarantee. If a laboratory ever finds otherwise, we'll offer a full refund.
Red Flags When Buying a Jade Bracelet
A few warning signs are worth watching for before you buy, regardless of what the home checks suggest:
- A price that seems too good to be true. Genuine, well-textured Type A jadeite simply isn't cheap, and a heavily discounted "natural jade" bracelet is a reason to ask more questions, not fewer.
- Perfectly uniform, glassy colour. Natural jade almost always shows some variation. Flawless, printed-looking colour is a common sign of dye or glass.
- No disclosure of treatment or origin. A seller who can't or won't tell you whether a piece is Type A, B, or C, or where it was sourced, hasn't earned your trust yet.
- No return policy or authenticity guarantee. Reputable jewellers stand behind their claims. If there's no way to get your money back, should a lab prove otherwise, that's worth pausing over.
- A plasticky feel or unusual lightness. Trust your hands here. If it doesn't feel as substantial as the price suggests, ask more before buying.
Buy Real Type A Jade With Confidence
The cold test, the weight in your hand, the sound of beads tapping together: these are all worth doing, and worth trusting as far as they go. However, doing these checks alone cannot tell you with certainty whether a bracelet is Type A, Type B, or Type C. That’s why you need to find a seller who backs that up with an actual guarantee.
Every bracelet at The Jade Galleria is natural Type A jadeite, verified and backed by our own authenticity guarantee, so you're not left relying on a cold test and a guess.

FAQ
Is jadeite real jade?
Yes. Jadeite and nephrite are both genuine forms of jade. Jadeite is the rarer and generally more valuable of the two, prized for its wider colour range and glassier lustre.
What is Type A jade?
Type A jade is natural jadeite that hasn't been chemically bleached, dyed, or resin-filled. It may be waxed as a traditional finishing step, but nothing beyond that. It's the standard collectors and reputable jewellers consider genuine.
Can fake jade pass the cold test?
Some can, particularly other natural stones or well-made glass. The cold test is a useful first signal, not proof, which is why it should always be paired with buying from a seller who guarantees Type A jade.
Does real jade scratch glass?
Yes, genuine jade is harder than window glass and most household metals, such as steel. That said, we don't recommend scratch-testing your own jewellery at home, since it risks permanently damaging a genuine piece, and the result still isn't conclusive on its own.
