Pearl is an organic gemstone containing calcium carbonate, which is mainly produced in the molluscs of pearl shells and nacre. Its chemical composition is CaCO3 (calcium carbonate). The specific gravity of pearls is about 2.60 to 2.85, and the Mohs hardness is between 2.5 and 3.0. The refractive index range is 1.52~1.69.
As early as 200 million years ago, pearls existed on the earth and became people's favorite jewelry, which has been passed down to this day. Ancient people in the Middle East regarded pearls as "tears falling from heaven." Their romantic colors and round and soft appearance made pearls a favorite of women and a timeless accessory.
The general color of pearls is white, but there are also some pearls with pink, yellow, green, blue, purple, brown or black colors, which are colorful and rich. The shapes of pearls are also quite diverse, including round, pear-shaped, egg-shaped, teardrop-shaped, button-shaped and arbitrary shapes, among which round is the best. Pearl clams in the tropical areas of the South China Sea have a long life cycle and can produce larger and perfect pearls. They were the main pearl producing area in the Middle Ages.
In the past history, freshwater clams in Heilongjiang could also produce pearls, but the color was opaque and pure white, and the output was very small. During the Qing Dynasty, they were used as rare tributes and were called "Eastern Pearls." Only members of the royal family could wear East Pearl jewelry.
