Tahitian Pearls Defined

Tahitian pearls are bead-nucleated pearls grown in the gonad of the Pinctada margaritifera mollusk in French Polynesia.

Tahitian Pearls - Among the Most Beautiful in the World

Tahitian pearls are produced in the black-lipped oyster Pinctada margaritifera, in and around Tahiti and the French Polynesian islands. This oyster itself is quite large - sometimes over 12 inches (30 cm) across and weighing as much as 10 pounds (4.5 Kg) - which often results in much...

Cultured Pearls Defined
A cultured pearl is any pearl grown with the influence of human intervention.

Cultured Pearl Formation
A pearl is formed when a something penetrates or lodges in the mantle tissue of a mollusk. In response, a substance called nacre is secreted, and the creation of a pearl begins. Nacre is a combination of crystalline and organic substances. The nacre builds up in layers and after a few years, this buildup of nacre creates a pearl.

THE FIRST COMMERCIAL PEARL OYSTER FARM IN THE WORLD

It is at this particular crossroad that we find a Mexican-French Medical Doctor by the name of Gastón Vivès, attempting what very none had tried before: initiate a commercially viable, large-scale pearl oyster farm to produce shell and pearls. The Vivès family owned a pearl fishing armada in La Paz, Baja California Sur, and they were experiencing diminishing profits every year, thus wanting to revert this trend we find Gastón Vivès...

Although it is not about PEARLS (but it may include them), some of you may find it interesting, so here is the information:

The origin of a gemstone, namely the geographic location at which it was extracted from the earth, has for years posed substantial scientific challenges to the gemmologists who are called on to make definitive judgements.

The current focus on supply chain integrity and traceability means that the concept of origin has expanded and is more relevant than ever before...
