Where are the black pearls?

Black pearls are a kind of bronze pearls and belong to very precious jewellery varieties. It symbolizes the crystallization of hard years, and is known as the tears of the mother's pain. It is rare and noble after suffering.

In ancient China, black pearls represented wisdom. It is guarded between the dragon's teeth, giving off a seductive luster. But whoever wants to get it, whoever wants to conquer the dragon. The dragon's hugeness and divine power are daunting. Therefore, those who can conquer the dragon must have extraordinary wisdom and courage. Such people are worthy of the black pearl.

Before the black nucleus Nanyangzhu was successfully put on the market, the only black pearls that could be sold were rare and very expensive natural black pearls, or faded Japanese nucleated akoya pearls, which are made of nitric acid. The silver is black, and there is a small part of the imitation black pearl. In the past three decades, the pearl culture of the French Polynesia has been successfully developed. In 1976, the Gemological Institute of the United States identified the cultured black pearl of Tahiti as "a cultured pearl with natural color."

The pearls in the tropical regions of the South China Sea have a long life cycle and can produce large and perfect pearls. They are the main pearl producing areas in the Middle Ages. The freshwater scorpion in Heilongjiang can also produce pearls, but the color is opaque, pure white, and the yield is very small. In the Qing Dynasty, as a rare tribute, it is called "Dongzhu". Only the royal members can wear Dongzhu jewelry.

Black Pearl has only two major natural origins: one is the Tahiti Island of the Polynesian Islands, which produces 95% of the world's black pearls; the other is the Penglin Island and Majuhiki Island of the Cook Islands, which account for the total production. 4%. Other Pacific island production is less than one percent. These two regions live together in the south-central Pacific Ocean, so it is also known as the Black Pearl.

The annual production of quality black pearls is estimated to be no more than 150,000, of which 40% are sold through the annual international auction. Most black pearls have a particle size between 9mm and 10mm, and more than 60% of the black pearls have a particle size of no more than 11mm. Therefore, 11mm is generally regarded as the limit of the treasure of black pearls, and the fine round black pearl of 15mm or more is very rare, and even the ready-made products can be referred to the market price, which shows that it is expensive and rare.
