Jade is a beautiful and culturally significant gemstone that has been treasured for thousands of years. However, with the resurgence in popularity of jade jewellery, it is important to be able to distinguish real jade from imitations, especially since jade is the most imitated gem material. Fake jade is often made from materials such as glass or plastic, which are not as dense as real jade. Here are some tests to help you differentiate between real and fake jade.
| Characteristics | Values |
|---|---|
| Colour | Jade comes in a variety of colours, including green, white, yellow, and lavender. The most valuable variety is brilliant green jadeite, also known as imperial jade. |
| Texture | Real jade should feel cool to the touch and have a dense, solid feel. Fake jade is often made from materials such as glass or plastic, which retain heat more easily and feel lighter. |
| Weight | Jade can feel heavier than expected compared to other gems of the same size. |
| Sound | When two pieces of jade are tapped together, they should produce a deep, resonant sound. If the sound is more like plastic beads, it is likely fake. |
| Scratch Test | Jade is a very hard stone with a hardness of 6-7 on the MOHS hardness scale. It should be difficult to scratch with a metal object or fingernail. |
| Light Test | Real jade will not emit light in the dark or fluoresce under UV light. |
| Price | While real jade can vary in price depending on quality and colour, it is unlikely to be sold at a bargain price. |
| Expert Evaluation | It is recommended to consult a gemologist or jeweller to evaluate the stone's structure, properties, and density to determine its authenticity. |

What You'll Learn
Feel the temperature: real jade stays cool to the touch
One of the most distinctive characteristics of real jade is that it stays cool to the touch. Even if you rub it against your skin or squeeze it tightly in your palms, it will not warm up. This is because jade is very dense. Fake jade, on the other hand, is often made from materials such as glass or plastic, which are not as dense and therefore retain heat more easily.
To perform a temperature test, hold the jade in your hand for a couple of minutes. If it warms up, it is likely not real jade. You can also try rubbing it between your hands for a couple of minutes. If it still feels cool, it is likely genuine jade.
It is worth noting that while these tests can provide some indication of whether jade is real or fake, they are not foolproof. The most sound way to know the grade of your jade is by consulting an expert. They will be able to tell you the quality and value of your piece. A jeweller can examine the stone under a magnifier to make sure it has the structure of a true jade and to check for signs of a fake. They can also perform a density test, measuring the density of the stone and comparing it to a jade density chart.

Weigh it: jade is heavier than you'd expect
Weighing a piece of jade is a simple and effective way to determine its authenticity. Fake jade is often made from lighter materials such as glass or plastic, so if the stone feels light or hollow, it is likely a fake. Real jade, on the other hand, is denser and heavier than expected for its size. This weight is due to its density, which is higher than that of many other stones.
One way to test the weight of jade is to toss it in the air and catch it in your palm. If it feels heavier than you expected, it might be real jade. This "toss test" is a popular method used by both buyers and sellers. It is a simple test that anyone can perform, but it is not a surefire way to determine authenticity.
Another way to test the weight of jade is to use a spring scale. This method is more precise than the toss test and can give you an exact weight measurement. First, use crocodile clamps to grasp the jade item. If your scale does not have clamps, you can wrap the jade with a piece of string or a rubber band. Lift the scale by the top handle and write down the weight of the jade item in air. Then, gently lower the jade into a bucket of water and record its weight again. Subtract the weight in water from the weight in air to find the volume in cubic centimetres (cc). Finally, calculate the density by dividing the weight in air by the volume. Jadeite jade has a density of 3.20-3.33 g/cc, while nephrite jade has a density of 2.98-3.33 g/cc. If your jade's density falls within these ranges, it is likely authentic.
While the weight and density of jade can provide valuable clues about its authenticity, it is important to remember that these tests are not foolproof. The best way to know for sure if your jade is real is to consult a professional gemologist or a reputable jade expert.

Scratch it: jade is hard and difficult to scratch
While it is difficult to determine whether a stone is real or not without the help of a professional, there are some tests that can help you identify whether a piece of jade is real or imitation. One of the most well-known tests is the scratch test.
The scratch test involves attempting to scratch the surface of the stone with your fingernail, a piece of metal, or a steel blade. If the stone is scratched, it is not real jade. This is because jade is a very hard stone, with a hardness of 6-7 on the Mohs scale, which means it has excellent resistance to scratching. In fact, jade is harder than steel, so if you use a steel blade to try to scratch jade, it will not leave a mark.
However, it is important to note that jade can still break or smash easily, despite its hardness. This is because brittleness is defined as toughness, or resistance to breaking, and jade is a very brittle stone. So, while it may be difficult to scratch jade, it can still be vulnerable to breaking if dropped or hit with enough force.
The scratch test is a simple and effective way to help determine whether a piece of jade is real or imitation. However, it is always a good idea to get a stone evaluated by a professional jeweler or gemologist before making any purchases, as they can perform a variety of tests to determine the authenticity of the stone.

Inspect the colour: jade's colour should be consistent but not perfect
Jade is a beautiful and culturally significant gemstone that has been treasured for thousands of years. It is a metamorphic rock that occurs in a variety of colours, including green, white, and lavender, and is prized for its beauty and lustre. However, not all jade on the market is genuine, and it can be challenging to distinguish real jade from imitation.
One crucial aspect of identifying real jade is inspecting its colour. Genuine jade should exhibit a consistent colour throughout the stone. However, it is important to remember that the colour should not be too perfect or uniform. Slight variations and imperfections in the colour are indicative of authentic jade. This is because each piece of jade is unique, and no two stones will ever be exactly alike.
The specific shade of green can also provide clues about the type and quality of jade. Jadeite, the more precious and rarer variety, is known for its brilliant green colour, often referred to as imperial jade. This variety tends to be more expensive due to its rarity and vibrant hue. On the other hand, nephrite jade, which is more abundant, typically displays darker shades of green, such as olive green, or other colours like yellow or white.
It is important to be cautious when examining the colour of jade, as some imitation stones can closely resemble the coloration of real jade. For example, serpentine, a jade substitute, exhibits similar green shades but is softer and will not pass the scratch test. Additionally, pure grossular, which is typically white, can also be found in green, red, and yellow varieties, with the green variation being marketed as Transvaal jade.
While inspecting the colour is an important step in identifying real jade, it should not be relied upon as the sole method of authentication. It is always recommended to consult a professional jeweller or gemstone expert for a definitive verdict on the authenticity and quality of jade. They can perform additional tests, such as evaluating the stone's density, structure, and response to heat, to provide a more comprehensive assessment.

Consult an expert: only a jewellery expert can give a final verdict
While there are several at-home tests that can help you determine whether a piece of jewellery is made of real jade, only a jewellery expert can give a final verdict.
Jewellers are trained to recognise real and fake precious gems and stones. They can examine the stone under a magnifier to make sure it has the structure of a true jade and to check for signs of a fake. They will evaluate the properties of the stone and then tell you if it’s real or fake.
To ensure that you're purchasing a genuine and high-quality jade item, it's always best to consult with a professional gemologist or reputable jade expert. Buying from a trusted source guarantees that you're acquiring an authentic piece of jade.
If you're still unsure about the authenticity of your jade, you can always take it to a local museum and ask their experts to examine it.
Remember that each piece of jade will vary slightly since no two stones will ever be exactly alike.

Frequently asked questions
The most reliable way to know if your jade is real is by consulting an expert. They will be able to tell you the quality and value of your piece. However, there are some simple tests you can perform at home to determine whether your stone is the real deal.
One distinctive characteristic of this natural stone is that it's usually cold, so you'll immediately feel its coolness when you hold it. Real jade should also have a dense, solid feel. Fake jade is often made from materials such as glass or plastic, which are not as dense as real jade. If the stone feels light or hollow, it is likely fake.
Yes, you can try the clicking test. This is done by tapping the jade and a plastic stone together. If you hear a sound like a plastic bead, the jade is fake; if you hear a deep, resonating sound, it's real. You can also try the toss test, which involves throwing the jade in the air and catching it in your palm.
Real jade should feel cold when held in the hand, and the colour should be consistent but not perfect—the surface should have imperfections. Jade comes in a wide range of colours and may be worn in various ways, but there are two main varieties: nephrite and jadeite. Jadeite is rarer, denser, and more challenging, and it is available in a more extensive selection of hues.
