Pearl diving has been performed for centuries, we have records back to about four thousand years ago, in the Persian Gulf the Summarians had practiced pearl diving. Approximately two thousand years ago the Japanese had begun to hunt for pearls, their divers were mainly women, they were believed to be better divers and were refered to as ''amas'' which translates to sea woman. The australians in the early seventeenth century had also presented the pearl industry. The reality in today's society where pearl diving (also known as pearl hunting) exists, it consists of diving into deep waters populated by pearl producing oysters or freshwater pearl mussels, followed removing them from the bottom of the sea to examine them and extract a pearl, they are very rare usually. The matter of the fact is we find three or four high quality pearls among an entire ton of oysters. This also supports the reasoning for their great expense. However, a large majority of pearl hunting today is based on exploration and hobby rather than financial interest, mainly because most pearls aren't harvested naturally.
