The black lipped oyster (Pinctada Margaritifera) which can only
live in nutrient rich tropical waters lives in abundance in the lagoons of French Polynesias
coral atolls. |
| These oysters create the famous black pearls. Most "black" pearls actually range in color from
silvery gray to dark black. Other rare colors such as blue, green, and violet are possible as
well. Black pearls range in size from 8mm to 12mm. Sizes larger than 12mm are rare and the
largest ever found is around 22mm. |

The Black Lipped oyster seen opened. The white ring is the
inside of the shell and the black material inside that is the
mantle which secretes the nacre.

Pearls have always been prized since ancient times. The Romans used caches of pearls to fund
entire war campaigns. It wasn't until the early twentieth century, however, that pearls began
to be cultured. Techniques developed by Tatsuhei Mise, Tokichi Mishikawa, and later Kokichi Mikimoto
allowed man for the first time to induce pearl formation in oysters.
It wasn't until the early 70s that the methods of pearl farming reached Polynesia. And not the
90s that their beautiful pearls have become well known. Join us as we take you along on our
quest for the black pearl.

Here is Teiki harvesting a black pearl. He has to be very
careful so as not to kill the oyster. A single oyster can be grafted 2-3 times in its
lifetime. When they get old they are either eaten or sent back to the lagoon to spawn.

Jeremiah, our adventurous leader decides to try his hand at
extracting a pearl. He says it isn't as easy as it looks. But in this picture he finally
gets the pearl and doesn't kill the oyster while doing it. | |
| Opening the pearl is very tricky. You have to open it enough
so as to get the pearl out but no so far as you kill the oyster. Here we see a nice
black pearl emerging from the oysters pearl sack. |
