Jewelry for all, Lok Tai Fook introduces you

Coral is a beautiful gemstone that looks like a tree and a flower, so it was once considered a plant, until it was later learned that coral is an organic gem formed by the remains or secretions of a coelenterate animal, a polyp. Corals, especially the red corals in them, its bright red color is very popular with people, coupled with the scarcity of red corals, so the value of red corals is very high. However, there is no shortage of corals in the market, but there are many imitations of corals. So, how do you identify corals? Let's talk about the little knowledge of coral identification.

To identify corals, we must first grasp the natural characteristics of corals. Pure natural coral jewelry has the following characteristics: 1. There is a natural diagonal texture, and each piece of coral is different. 2． There are natural flaws, such as small white spots, small black spots, small spots are normal, not bad products. 3. The color of red coral is from the inside out, that is, the color of the inner part of the red coral is relatively light, the color of the surface layer is darker, if the color of the inner and outer layers of the red coral is very consistent, then you have to be careful that it is dyed; the growth pattern of the red coral is characterized by the longitudinal growth pattern of the red coral in the direction of its growth, and parallel to the growth direction; on the cross-section of the red coral, there are concentric circular growth patterns like the annual rings of the tree, according to which the true and false red corals are carefully identified.

The identification of corals can also be identified by the characteristics of counterfeit corals, such as the identification of red corals, which can be identified by mastering the characteristics of imitation red corals, such as dyed red corals rubbing the surface of corals with cotton swabs dipped in alcohol, and there will be a phenomenon of discoloration, while natural red corals do not have this phenomenon. In addition, the main substitutes for imitation corals are celluloid, wood and sealing wax, none of which have the unique appearance of corals, so careful identification can still distinguish the authenticity of corals.
