The difference between mother-of-pearl and pearl;
1, artificial difference
Mother-of-pearl is artificially post-processed, and pearls are usually divided into natural pearls and cultured pearls. Natural pearls are mainly produced in mollusks such as Pinctada and Pinctada, which are produced by the endocrine function of these shellfish. Mineral (aragonite) beads containing calcium carbonate are composed of a large number of tiny aragonite crystals.
2. Differences in commodity values
The inner core of shell beads is all synthetic, and the outer coating is also synthesized by chemical raw materials. Zhu Bei is a kind of fake pearl, and it is a kind of handicraft that can only be made through multiple advanced processes, and there is no jewelry level. And "high-end atmosphere" is synonymous with pearls. This precious organic gem, also known as "five emperors and one queen", includes diamonds, rubies, sapphires, emeralds and opals.
3. Differences in product appearance
The outer surface of shell beads can be plated with various colors as required, such as silvery white, golden yellow, malachite green, Kong Quelan, jet black and so on. The color of shellfish skin is not natural, but dyed in the later stage. Generally speaking, it will not fade, but it is not wear-resistant and the skin is easy to scratch. There are usually only three colors in the color of pearls: white, gold and black.
Extended data:
Characteristics of mother-of-pearl:
It has the efficacy and brightness of natural pearls. Compared with cultured pearls, the pearls are larger, rounder and less defective, and the luster is very similar to that of high-grade Tahiti pearls. In other respects, it is like a seawater pearl, with a round core in the middle and a nacre outside, and its nacre is much thicker than ordinary seawater pearls, so it is not easy to wear, let alone discolor, and it is rich in colors.
However, if the shell beads are worn for a long time, they will lose their epidermis, thus losing their original luster and beauty. As long as it is not caused by chemical corrosion, the skin luster of natural pearls can remain unchanged for decades. Pearl is bred by mussels, and its luster and pearl body have a certain life. Exposed to air for a long time, the nacre will turn from white to yellow after oxidation. Usually, the shelf life of a pearl is about 100 years.
