What is a "natural pearl"?


Over the past decade, the pearl market has considerably evolved.

First, the market was flooded with freshwater pearl from China growing whiter and bigger, they now compete with watersea Japanese pearls.

The cultured pearl being more abundant, the price of naturel pearls has increased.

But what is the difference between a natural pearl and a culture pearl?
In fact, the natural pearl is naturally formed in oysters without human intervention. It's often a parasite, a grain of sand, which is housed in the mantle, flesh or reproductive organ of an oyster which will produce irritation. The snail will then secrete a substance called mother of pearl.

This organic substance added to calcium carbonate needs up to ten years to accumulate and give birth to the final "fine pearl". The difference in color, shape and size is based on several factors.

No fine pearl is identical to another.

The real pearls are, in fact, became very, very rare and highly sought after.

Cultured pearl, as its name suggests, is cultivated by man.
It is obtained by inserting what is called a nucleon (or nucleus), placed through an incision in the reproductive organ of the oyster. We then add a piece of mantle of an oyster shell which is beautiful and of good quality.

  We have to wait between 12 and 24 months for a pearl to grow.

Several beads can be produced simultaneously in the same oyster.

Pearl farms are mainly in French Polynesia, in Japan and in Australia.

Diamonds are not the only one to reach high prices at Auction

The pearls are attracting more and more desires.
There was a time when the pearl disputed to diamond the status of "women's best friend".

Ladies could not imagine to get out during the day without a hat ... and some rows of pearls.
The size of
the latter, as well as the length and the number of rows gave a very accurate state of fortune of the lady and her husband.
In fact, before the invention of cultured pearls,
fine pearl were worth as much as diamonds.
