If you want to know how to tell if jade is real, start by separating two different questions:
Is the stone actually jade? Some jewellery sold as jade is really serpentine, aventurine, dyed quartz, glass or plastic.
If it is jade, has it been treated? Real jadeite may be bleached and polymer-impregnated, dyed, or both. It is still jadeite, but it should not be described or priced as untreated Type A jadeite.
You can check the weight, temperature, surface, colour and sound at home. These non-destructive tests may reveal warning signs, but none can conclusively identify jade or confirm whether it has been treated.
Quick answer: how can you tell if jade is real?
Real jade often feels substantial for its size and may stay cool briefly in the hand. Depending on whether it is nephrite or jadeite, it may have a softly waxy, greasy or more glass-like lustre. Under close inspection, you may also see a fine, interlocking internal texture.
However, glass, quartz, serpentine and treated jadeite can display some of the same characteristics. Home tests can help you spot obvious imitations, but a report from a recognised independent gemmological laboratory is the most reliable answer for a valuable piece.
1. Feel the weight and temperature
Jadeite and nephrite often feel cool and substantial when you first pick them up. Lightweight plastic imitations usually warm quickly and may feel noticeably lighter.
However, the cold test is much less conclusive than it sounds. Glass, quartz, serpentine and many other stones can also feel cold against the skin, especially when the room is cool. Differences in size, thickness and setting also affect how quickly a piece warms up.
May indicate: a very light or warm-feeling piece could be plastic or another lightweight imitation.
Cannot confirm: that the stone is jade, whether it is jadeite or nephrite, or whether it has been treated.
2. Examine the surface in angled light
Hold the piece beside a window and tilt it until the light skims across its surface.
Nephrite often has a soft, greasy or waxy lustre. Well-polished jadeite may appear brighter and more glass-like. This difference is important: genuine jade does not always have a waxy finish, so shine alone is not a reliable authenticity test.
Look instead for a fine, interlocking texture beneath the surface. Depending on the material and polish, nephrite may appear faintly fibrous, while jadeite can show a more granular texture.
Glass is often very smooth and may contain round bubbles. Bubbles can be a useful warning sign, although their absence does not prove that a piece is jade.
Some heavily treated Type B jadeite may show an unusually uniform appearance or fine etched-looking texture under magnification. Well-treated material, however, can look completely convincing to the naked eye.
May indicate: round bubbles can suggest glass, while an unusual surface texture may justify further testing.
Cannot confirm: jadeite versus nephrite or the presence of polymer treatment.
3. Check how the colour is distributed
Natural jade often shows variations in colour, translucency and internal texture. Its colour may appear in patches, clouds, veins or gradual transitions rather than as one flat, artificial-looking shade.
That does not mean genuine jade must always be uneven. Some natural jade can have relatively consistent colour, and a uniform appearance alone does not make it fake.
Look closely around fractures, grain boundaries and drill holes. Dye may collect in these areas and appear as more intensely coloured lines or patches. On a bead, the material inside the drill hole may also be paler than the surface.
An unusually bright or acidic-looking green can be a warning sign, but colour preferences and lighting make this highly subjective.
May indicate: colour concentrated in cracks or around drill holes may suggest dye treatment.
Cannot confirm: that colour is natural or that colourless resin treatment is absent.
4. Look through the stone with a small light
If the piece is translucent, shine a small torch through it from behind. You can also use a 10× loupe or your phone’s macro setting to examine it more closely.
Transmitted light may reveal colour zoning, fractures, bubbles or variations in internal texture that are difficult to see from the surface. Colour concentrated along cracks may suggest dye, while round bubbles can indicate glass.
Do not expect every genuine jade piece to transmit light. Lower-grade jadeite and much nephrite can be opaque, and thickness has a major effect on translucency.
May indicate: internal texture, bubbles or suspicious colour concentration.
Cannot confirm: whether the stone is untreated Type A jadeite.
5. Listen to the sound
The sound test is most useful for solid bangles and loose beads.
An intact jade bangle may produce a clear, resonant tone when tapped very gently against another hard object or a known jade reference. Plastic usually produces a noticeably flatter sound.
However, thickness, shape, internal fractures, mounting and treatment can all change the result. Glass may also ring, while a genuine jade piece with a fracture may sound dull.
Avoid tapping valuable pieces together, as this may chip or damage them.
May indicate: supporting evidence when comparing similar intact bangles or beads.
Cannot confirm: whether a piece is jade or whether it has been treated.
Jade tests you should not use
Some popular online tests are unreliable and may permanently damage your jewellery.
The scratch test
Jadeite and nephrite are relatively resistant to scratching, but trying to scratch jewellery with a knife or steel tool is not a reliable identification method.
Steel tools vary in hardness, surface coatings can affect the result, and several jade imitations may also resist casual scratching. The test cannot determine whether jadeite has been bleached, polymer-filled or dyed—and you may leave a permanent mark on the piece.
The flame or hot needle test
Heating the stone or touching it with a hot needle is sometimes recommended as a way to detect plastic or resin.
Do not do this. Heat can damage surface wax, discolour polymer inside Type B jadeite, weaken adhesives and permanently mark a piece that contains genuine jade.
The cold-on-the-cheek test
Many stones, as well as glass, initially feel cold against the cheek. This sensation depends on the room temperature, the size of the piece and how long it has been handled.
It may help identify obvious plastic, but it is not a jade test.
The sound test on mounted jewellery
Rings, earrings and pendants are affected by their metal settings, adhesives and surrounding components. Their sound provides little useful information and tapping them may loosen the stone.
What are Type A, Type B and Type C jade?
The A, B and C terminology is used primarily to describe jadeite treatment. It is not a universal quality grading system for every stone sold as jade.
- Type A jadeite: Has not been acid-bleached, polymer-impregnated or dyed. Traditional surface waxing is generally permitted within the Type A classification.
- Type B jadeite: Has been chemically bleached and impregnated with a colourless polymer or resin to improve its appearance and translucency.
- Type C jadeite: Has been artificially dyed to alter or intensify its colour.
- Type B+C jadeite: Has been both bleached and polymer-impregnated, and dyed.
Types B and C are still jadeite, but they are treated jadeite and should be clearly disclosed as such. Treatment can affect durability, appearance and value.
The A, B and C labels should also not be confused with ordinary quality grades. A Type A piece can still be pale, opaque, included or inexpensive; Type A describes treatment status, not beauty or market value.
What actually proves whether jade is real?
For an important or expensive purchase, the safest answer is a report from a recognised independent gemmological laboratory.
A laboratory can identify whether the material is jadeite, nephrite or an imitation. Specialist testing, including infrared spectroscopy, may also be used to detect polymer impregnation in jadeite.
Do not rely only on a generic card supplied by a seller. Check:
- The name of the issuing laboratory
- Whether the report number can be verified
- Whether the material is identified as jadeite or nephrite
- Whether treatments are disclosed
- Whether the report refers to the exact piece being sold
A laboratory report is especially important when a seller uses terms such as Type A jadeite, untreated jadeite, icy jadeite, imperial green jade or investment-grade jade.
Buying jade for everyday jewellery
Not every affordable jade piece needs an expensive laboratory report. Jadeite and nephrite both span a wide range of colours, translucencies and quality levels, so genuine jade does not have to be expensive.
For everyday jewellery, buy from a seller who describes the material and any known treatment as clearly as possible. The listing should tell you whether the stone is jadeite, nephrite or another green gemstone rather than relying only on the broad word “jade”.
Serpentine, aventurine and dyed quartz can all be attractive stones in their own right. The problem is not the material—it is selling one stone under another stone’s name.
At GemBee, we aim to describe the gemstone identity and treatment information available to us clearly, so you can better understand what you are buying.

Frequently asked questions
What is fake jade usually made from?
Common jade imitations include serpentine, aventurine, dyed quartz, glass and plastic. Other materials may also be marketed under informal names containing the word “jade”, even though they are neither jadeite nor nephrite.
Treated jadeite is a separate issue: Type B and Type C material is real jadeite, but it is not untreated Type A jadeite.
Does real jade feel cold?
Jade often feels cool when first touched and may take a little time to warm. However, glass, quartz, serpentine and many other stones can feel similar. The cold test may help rule out lightweight plastic, but it cannot confirm that a stone is jade.
What does real jade look like?
Real jade varies enormously. Nephrite often has a softly greasy or waxy appearance, while polished jadeite may have a brighter, glass-like lustre. Natural colour can be mottled, cloudy, veined or relatively even, depending on the piece.
No single colour, texture or degree of translucency proves authenticity.
Is all real jade green?
No. Jadeite and nephrite occur in a range of colours. Jadeite can be green, white, lavender, yellow, orange, red, brown, grey or black. Nephrite is commonly green, cream, white, brown or grey.
Colour alone cannot identify jade.
What is Type A jade?
Type A jadeite has not been acid-bleached, polymer-impregnated or dyed. Traditional surface waxing is generally accepted. Type A refers to treatment status rather than quality, so untreated jadeite can still be inexpensive.
Are Type B and Type C jade fake?
Not exactly. Type B and Type C pieces are made from real jadeite, but they have been treated.
Type B jadeite has been bleached and polymer-impregnated. Type C jadeite has been dyed. Type B+C jadeite has received both treatments. These treatments should be disclosed because they affect value and may affect long-term durability or colour stability.
Can you test jade reliably at home?
Not definitively. Weight, temperature, colour distribution, magnification, transmitted light and sound may reveal warning signs, but none can conclusively identify jade and its treatment status.
For a valuable piece, use a recognised independent gemmological laboratory.
Is serpentine the same as jade?
No. Serpentine is a different mineral material and is generally softer and less tough than jadeite or nephrite. It is sometimes marketed using names such as “new jade”, although it is not true jade.
Serpentine can be an attractive and affordable green stone, but it should be accurately labelled and priced as serpentine.
Should I scratch jade to test whether it is real?
No. A scratch test is unreliable, cannot identify treatment and may permanently damage the jewellery. Use non-destructive observations or professional gemmological testing instead.
Why is some real jade so cheap?
Jade covers an enormous range of qualities. Price depends on whether the material is jadeite or nephrite, as well as its colour, translucency, texture, size, craftsmanship, condition and treatment status.
Lower-grade jadeite, nephrite and treated jadeite can all be genuinely affordable. A low price does not automatically mean a piece is fake—but vivid, highly translucent jadeite sold for an implausibly low price deserves extra scrutiny.
