Pearl is an ancient organic gemstone. It is produced in pearl mollusks and nacre mollusks. The mineral (aragonite) beads containing calcium carbonate produced by endocrine action are composed of a large number of tiny aragonite crystals. Made.

According to the research of geology and archaeology, there were pearls on the earth 200 million years ago. The international gemstone community also lists pearls as the lucky stones for the June birthday, and the commemorative stones for the 13th and 30th wedding anniversary are often used in wedding jewelry customization, which is a testimony of the love and lingering affection of the couple. Pearl Pearls with magnificent colors and elegant qualities, symbolizing health, purity, wealth and happiness, have been loved by people since ancient times.

Pearls are spherical, oval, irregularly spherical or oblong, with a diameter of 1 la 6 mm. The surface is white, yellow-white, light pink, light blue, etc., with beautiful colorful luster and smooth. Most pearls used as ornaments have perforations in the center. The quality is hard, hard to break, and the section is layered. There is a cracking sound when burning with fire. It is better to have round particles, transparent luster, bright and hard texture.

Pearls, agates, crystals and jade are also called the “four treasures” in ancient Chinese traditions, and they often appear in ancient jewelry.

Formation principle

The mantle of the mussel is stimulated by the intrusion of foreign matter (sand grains, parasites). The epidermal cells in the stimulated area take the foreign matter as the nucleus and sink into the connective tissue of the mantle. Part of the entrapped mantle epidermal cells divide by themselves to form a pearl sac. The cells secrete nacre, which coats the nucleus layer by layer to form a pearl. The foreign body is called “nucleated pearl”.

After the outer epidermis of the mantle is pathologically stimulated, a part of the cells divide and then separate, and then it is coated with the organic substances secreted by itself, and at the same time gradually sinks into the connective tissue of the mantle, forming a pearl sac and then forming a pearl. Since there is no foreign matter as a nucleus, it is called a “nuclear pearl”.

Now the artificially cultivated pearls are based on the above principles and artificial methods are used to cut small pieces of living epithelial cells (cell pieces) from the mantle of the mussels, and implant them together with the artificial nucleus prepared from the shell of the mussel. In the connective tissue, the small pieces of implanted cells rely on the nutrients provided by the connective tissue to rapidly proliferate around the artificial nucleus, form a pearl sac, and secrete nacre, thereby producing artificial nucleated pearls. Artificial seedless pearl is a pearl produced by implanting only small pieces of cells during the operation on the mantle. The cells proliferate to form a pearl sac and secrete nacre into the sac.
