Throughout history, the trends of wearing pearls jewelry have been considered both valuable and divine. Pearls are softer consistency of mineral gems. They require no cutting or polishing, because they have a natural glow. By 15 century, when civilization polishing technology became popular, the pearl was the king of jewels.
Pearl references abound in the ancient literature of Japan, known as "manyousyu" and "Kojiki." Only the noble elite and the rich can get the pearls, because of their rarity and value. In China during the 11th century, men attempted to grow pearls that were semi-spherical. Around the 13th century, men put a tiny lead Buddha inside of a mussel and made a “Buddha Pearl.”
A working technique for the production of “Cultured Pearls” came about in Japan. Kokichi Mikimoto produced the first ever semi-spherical cultured pearl in 1893. Later on, Kokichi Mikimoto, Shinpei Mise, and Tokichi Nishikawa discovered a way to culture spherical pearls.
Mikimoto cultured a pearl in 1905 with Akoya oysters that was spherical. Because of this success, the name Mikimoto and the cultured pearl of Japan became known all over the world.
European industry pearls in 1912 asked London and Paris to ban the sale of Japanese cultured pearls as real pearls. They said that pearls were of inferior quality. However, French and English scientists have proven that a natural pearl and cultured pearls were equal in both quality and composition.
The development of cultured pearl formed in the same way as the wild natural pearl. Pearls develop in the center of shells of mussels and oysters.
The center of a pearl in the wild is either a shell fragment or a sand grain. When the irritant comes into the shell, a pearl forms. Then, the mollusk secretes consecutive layers of calcium carbonate, called nacre, around the intruder. This instinctive defense mechanism makes the pearl.
One difference between a natural pearl and cultured pearl is whether or not irritate the uveden.Nadražujuće artificially cultured pearl is made from a conch shell called a pig-toe shell in the form of rounded grains. This shell has the genetic characteristics similar to those of Akoya oysters. This reduces the chances of rejection by oysters.
Whether natural or cultured, pearls all get to natural forces. Choosing between cultured and natural pearls jewelry is a matter of personal preference, their gender has been scientifically proven.
