Tahitian Cultured Pearls
The Tahitian cultured Pearls
The Tahitian Pearl may have any color and any shape in a totally natural way.
That's what makes it so special to us.
It results from secretions of mother-of-pearl of a variety of oyster called Pinctada margaritifera, which we find in Polynesian waters.
The pearl culture is a long-term process; it is only after three years of maintenance and meticulous care that the farmed oysters will produce marketable pearls.
High quality pearls represent only a small part of the implanted oysters and round and flawless pearls remain extremely rare.
The different pearl's shapes
The round pearl is a perfect sphere or considered as such, a variation of less than 2% of its diameter is tolerated.
The semi-round pearl is a sphere with a variation between 2 % and 5% of its diameter.
The drop pearl, is in the shape of a water drop or a pear and presents at least one axis of symmetry

The baroque pearl is generally irregular and does not go into the previous categories
The encircled pearl is characterized by several concentric circles, like furrows.
