Jade is a popular gemstone, but there are also many counterfeit jade products on the market. Therefore, it is very important to learn to identify the authenticity of jade. Here are some ways to identify the authenticity of jade.
1. Observe the appearance
Real jade usually has a natural texture and color, with a delicate and warm surface and a soft lusterCounterfeit jade products, on the other hand, often lack natural texture and color, and have a rough and dull surface, or are too showy. Therefore, observing the appearance of jade is an easy way to preliminarily identify the authenticity of jade.
Second, feel identification
There are also obvious differences between real and fake jade in terms of feel. The texture of real jade is delicate and warm to the touch, giving people a comfortable feeling;Fake jade, on the other hand, tends to have a rough texture, a dry touch, or is too greasy. Therefore, it is also one of the very practical methods to identify the authenticity of jade by feel.
3. Listen to the sound
Different jade materials have different sound signatures. For example, jadeite's sound is crisper and more pleasant, while Hetian jade is more dull. By gently tapping the jade and listening to its sound, you can preliminarily judge its authenticity. Generally speaking, the sound of real jade is relatively crisp, while the sound of fake jade is more dull or has no obvious sound.
Fourth, refractive index determination
The refractive index of different jade is also different. For example, the refractive index of jadeite is usually 1Around 66, while the refractive index of Hetian jade is 1Around 61. By measuring the refractive index of jade, it is possible to determine its authenticity. If the measured refractive index does not correspond to the standard value, the jade may be counterfeit.
5. Density determination
The density of different jade varies. For example, jadeite typically has a density of 333 or so, while the density of Hetian jade is 295 or so. By measuring the density of jade, it is possible to determine whether it is true or false. If the measured density does not match the standard value, it is a sign that the jade may be counterfeit.
6. Hardness determination
The hardness of different jade varies. For example, jadeite usually has a hardness of 6It is about 5-7, while the hardness of Hetian jade is 6-65 or so. By measuring the hardness of jade, it is possible to determine its authenticity. If the measured hardness does not match the standard value, it means that the jade may be counterfeit.
To sum up, identifying the authenticity of jade requires a combination of factors. In addition to the methods described above, it can also be identified by observing the fiber structure and bubble distribution inside the jade. When buying jade, it is recommended to choose regular merchants and brands to avoid buying fake and shoddy products. At the same time, it is also very important to carry out regular care and maintenance of jade.
