1, hardness
Real jade has a high hardness, and it is not easy to leave obvious marks when it is scratched by hard objects. Fake jade has low hardness, and it is easy to leave obvious marks on the surface, and it can't be repaired.
Step 2 color
The color of real jade is relatively light, very natural and has a bright and moist feeling. The fake jade is incongruous in color, looks awkward, looks grandiose and gorgeous, and looks like a painting.
3. Density
As long as there is an electronic scale and a bucket of water, it is convenient to measure the density. The density of jadeite is generally 3.32~3.34, and that of Hetian jade is generally 2.9~3. 1.
Observe the appearance of the original stone and pay attention to the following points:
1, observe the color of the original stone. Different jade colors will be different. For example, jadeite is usually dark green or light green, while Hetian jade is pale yellow or white. Turquoise is light blue or light green.
2. Observe the luster of the original stone. Emerald usually has a unique luster, which is different from ordinary stones. For example, jadeite presents a sharp glass luster, while Hetian jade presents a soft oily luster. Turquoise has a soft waxy luster.
3. Observe the texture and flaws of the original stone. Emerald usually has unique textures and flaws, which can help us identify it. For example, jadeite usually has emerald texture, while Hetian jade has fine texture and cotton wool defects. Turquoise usually has a blue texture and black iron wire.
