[Pearl]
Pearl, clear, with a maximum diameter of about 3.2 cm
There are three pearls in total, all of which are oversized and special-shaped sea pearls with iridescent luster
Pearl is produced by shellfish, and its main chemical component is calcium carbonate. It is generally white, and it is easy to turn yellow after long use, so it has the metaphor of “human aging pearl is yellow”. There are many large particles of seawater beads, but they are not as round as fresh water beads. Pearl is mainly produced in the Persian Gulf and China. China’s sea water pearls are mainly produced in the South China Sea, and the famous ones in history are Hepu pearls
