Pearl is one of the organic gemstones and the only gemstone in the world that grows in the body. Its main chemical components are CaCO3 (calcite), a small amount of inorganic matter and water. The latest science and investigations believe that the earliest pearls on the earth appeared in ancient times 200 million years ago. So early in the early days of mankind, this gleaming gem was discovered when primitive people searched for food along the coast and river. Pearl has always been favored by humans, and today it is still the most precious wealth of mankind.

Most of the species of the genus Pearl, which produces pearls, can be found in rivers in many parts of the world.
As for the formation of pearls, our ancestors have had some very fascinating theories. For example, the early history stated that when a drop of dew fell into the sea, it was just followed by an open oyster, thus forming a pearl. If the weather is good, a beautiful pearl can be formed, and if the weather is bad, the dew will become a black and faint pearl. By the 17th century, scientists had said that the formation of pearls was a function of sand entering the oyster shell, and another claim that pearls were undischarged eggs in oysters. The actual formation of pearls was finally confirmed in the 20th century.
In addition to our common pearls, there are some pearl-like substances found in many mollusks and other invertebrates. Although they are also calcium solidified bodies, there is very little pearl luster. The brilliance of the nacre in the pearl of the pearl. The calcareous solidified body in edible sea bream looks like a cherry kernel, which is neither dull nor valuable.

This solidified body is not as typical as pearls, has no nacre, but has a lovely pink color.
