Selection method of Zhou Dasheng's jewelry:
1, look at the shape, because jewelry contains different impurities, the color and shape of jewelry are also different. Jewelry can be identified according to its color and shape. For example, agate is generally concentric, mottled and banded, while malachite is mostly radial and concentric.
2, look at the hardness, can be identified according to the traces of jewelry, if diamonds, gems and other jewelry with relatively high hardness generally have no traces of damage, if traces are found, then the hardness of jewelry is not enough.
3. Look at the specific gravity, different kinds of jewelry have different specific gravity, which can be identified by the specific gravity of jewelry. Although many gems can be confused with real ones in color, luster, transparency and hardness, the proportion of jewelry is quite different.
