rose gold chain 18k The formation and acquisition of pearls

Nucleated pearls are divided into two parts, the nucleus and the nacre, from the inside to the outside. The innermost layer is the nucleus. The nacre is a crystal of keratin and calcium carbonate formed on the surface of the pearl nucleus or foreign body by the secretions of the pearl oyster during cultivation or growth. 일반적으로, the nacre of natural pearls and freshwater non-nuclear cultured pearls is very thick, while the nacre of nucleated pearls is relatively thin.

Pearl is a symbol of innocence, perfection, power and wealth, in addition to high medicinal value. Among all gemstones, pearls have the highest medicinal value and have been scientifically verified. Pearl powder can be taken internally or externally, and has a strong effect of nourishing skin, clearing fire and stopping bleeding.

Humans began to use pearls as jewelry and clothing for a long time. As early as the ancient Egyptian kingdom, the Persian kingdom and the ancient Roman empire, pearls were the darling of high-ranking officials. During the Middle Ages, European feudal masters banned anyone except the king from wearing and owning pearls. It can be seen that pearls had become the most high-end jewelry at that time.

In order to obtain more pearls, people in ancient times often paid the price of their lives. In pearl producing areas such as Japan, the Arabian Sea, 동남아시아, there are a group of women calledpearl pluckerswho specialize in pearl harvesting. They are specially trained to be master divers, and they have to dive for more than three minutes each time they dive to collect pearls. The big clam will be firmly attached to the bottom of the sea, and the pearl picker must reach into the clam to get the beads. If the pearl picker’s hand is caught in the clam and cannot break free in time, she will die. It can be said that the crystal pearl luster once alluded to the blood and life of the pearl plucking girl.
