Marine cultured pearls are produced in tropical or subtropical shallow waters, all using nuclear culture. Because of the nuclear nature of seawater pearls, the particles are generally larger and the ornaments are very good. China's seawater pearls are produced in the Beibu Gulf and the southeast coast. Historically, it is represented by the Hepu Pearl of Guangxi. It is called “Hepu Pearl, Nanzhu, and the Western Ocean is the West Pearl, and the Oriental Ocean is the East Pearlâ€. The international community has always believed that "West Pearl is not as good as East Pearl, and East Pearl is not as good as South Pearl." The shape of seawater pearls is generally round, which is the most ideal pearl. In ancient times, China was called "walking beads", that is, it was placed in the disk and moved slightly, and the Hepu South Pearl was round, the particles were light, and the particles were on the plate. The probability of a seawater pearl being round is higher than that of a freshwater bead, which is determined by its internal concentric annular structure. The beauty and elegance of seawater beads is largely due to its luster. The high-quality seawater pearls are semi-transparent, giving a soft and beautiful beauty. Under the short-wave ultraviolet rays, there are bright light blue, white, yellowish and pink fluorescence, and the X-rays are yellowish white and green phosphorescent.
