different types of pearls : black pearls

Black Pearls - Black Tahitian pearls are produced by the black-lipped oyster (Pinctada margaritifera) in the islands of French Polynesia. It’s relevant to note that Tahiti is the commercial center and trading hub for the bulk of the industry, and Tahiti itself does not have any pearl farms located on the island. The farms are instead scatted throughout French Polynesia. The oyster itself is quite large (12 inches across and weighing as much as 10 pounds), then the major feature of black Tahitian pearls is their large size. Black Tahitian pearls belong to the group of South Sea pearls and can measure between 9 and 17 mm. These black pearls do not require any artificial improvement, which is why they are admired as the "Queen of pearls". Sea Tahitians are cultivated in a mussel called Pinctada margaritifera. Due to the species outstanding qualities, Tahiti’s dark pearl production is considered as the world’s best.
