Basic information:

In some mollusks, pearl is a dense condensate, which is formed by the polymerization of true nacre around foreign particles, which are not attached to the shell or under the shell. It has various shapes, but the most typical ones are round and pear-shaped, with various colors, but they are usually white or light, with different degrees of luster, and can be used for decoration or medicine.

Pearl's English name is Pearl, which evolved from Latin Pernulo. Its other name is Margaret, which comes from ancient Persian Sanskrit, meaning "son of the sea".

As early as ancient times, when primitive humans were foraging by the sea, they found white pearls with colorful auras and were attracted by their crystal splendor. Since then, pearls have become people's favorite ornaments and have been passed down to this day.

China's natural freshwater pearls are mainly produced in Hainan Island. There are five kinds of pearls: white, red, yellow, black and variegated, and most of them are opaque.
