Are Pearls rare?
The most valuable pearls occur spontaneously in the wild, but are extremely rare. These wild pearls are referred to as natural pearls. Cultured or farmed pearls frompearl oysters and freshwater mussels make up the majority of those currently sold.
A cultured pearl is a pearl created by an oyster farmer under controlled conditions.Cultured pearls can be farmed using two very different groups of bivalve mollusk: the freshwater river mussels, and the saltwater pearl oysters.
Production. Majorica pearls are not formed in mollusks, but are man-made on solid glass balls coated with layers of pigmented and protective lacquers. They begin from high density dull glass with a specific weight, similar to that of real pearls.
A Japanese word also meaning "poppy" (ケシ, 芥子), it is used in Japanese for allpearls that grew without a nucleus. Originally, keshi pearls referred to those pearlsformed when a bead nucleus was rejected. More recently, keshi has been used to refer to second harvest pearls and even to freshwater non-nucleated pearls.
A nacreous pearl is made from layers of nacre, by the same living process as is used in the secretion of the mother of pearl which lines the shell. Natural (or wild)pearls, formed without human intervention, are very rare.
The Tahitian pearl (or black pearl) is an organic gem formed from the black lip oyster (Pinctada margaritifera). These pearls derive their name from the fact that they are primarily cultivated around the islands of French Polynesia, around Tahiti.
