facts about pearls, organic gemstone, freshwater, saltwater,white, grey, Akoya, Tahitian and South Sea

Pearl is the birthstone for June, the gem for the zodiac sign Gemini and the anniversary gem for the 3rd and 3oth wedding anniversary.

A pearl is an organic gem formed inside molluscs ( mussels in freshwater and oysters in saltwater ). When a foreign substance such as a food particle slips inside, the creature protects itself by covering the irritant with layers of nacre. As layers of nacre are build up over time the pearl is formed.

La Peregrina is the most famous natural pearl. At 50.96ct it is about the size of a pigeon’s egg. It was owned by King Ferdinand V of Castile (1452-1516), King Philip II of Spain (1527-1598) who gave it to his wife Queen Mary I (1516-1558) and also by Dame Elizabeth Taylor (1921-2011). The pearl was mounted in a Cartier necklace and in New York on December 2011 Christie’s auctioned it for $11.8 million US dollars.

The majority of pearls available today are cultured. Desirable natural pearls are extremely rare and as such are equally expensive. In fact, only one in approximately 10,000 oysters not in farms will ever produce a pearl, and of those, only a very small percentage would ever yield a gem that is the right shape, size and colour to be desirable.

Cultured pearls grow in saltwater or freshwater pearl farms. A nucleus, basically a round bead, is inserted into the soft tissue of the mollusc. From there the pearl growing process is the same as that of a natural pearl.
