History Of Pearls: Hunting & Farming

The difficulty of obtaining natural pearls made them more valuable and highly-priced.

How are pearls created?

A naturally occurring pearl is an organic gem. But searching for a pearl in the wild was an arduous task, requiring many divers and countless hours of searching. The difficulty of obtaining natural pearls led to the creation of pearl farming. It was discovered that an irritant could be artificially inserted into the mantle layers of a mollusk. The secretion made by the mollusk to cover the irritant is called the nacre, and it creates the pearl. With the invention of the culturing process, pearls became more available and less expensive.

Pearls were first cultured in Japan by Kokichi Mikimoto, who obtained a patent for his pearl farming process in 1896.
