When identifying corals, you should pay attention to imitations, such as imitations, chemical imitations, and bone imitations.
1. The imitation product is a coral made of burnt material. Its characteristics are color floating, unnatural, and the material surface is easy to find small hairy roads. It looks blued and soft, the surface is corrugated, the color is not bright, and the transparency is strong;
2. Chemical imitation products are chemically synthesized corals. When they are characterized, they are light in hand, sullen and soft, and the distance between the lines is equal and the distance between the grooves is the same.
3. Bone imitation, which is a coral made of bones, characterized by brown eyes and light body;
4. Coral lines are similar to human hand fingerprints, which is an important basis for distinguishing between true and false corals.
