The principal oyster beds lay in the Persian Gulf, along the coasts of India and Sri Lanka, and in the Red Sea. There are 2 types of pearls, that is saltwater and freshwater pearls. Do you know that Chinese pearls came mainly from freshwater rivers and ponds?

Chinese pearls come in a variety of hues including pink, apricot (yellowish orange), peach (pinkish orange), champagne (slightly pinkish yellow), plum (reddish violet), bronze (reddish brown), and every shade in between. Unlike black pearls, these pearls can be bleached white by prolonged exposure to the sun or by soaking the pearl in a bleaching agent for several hours. Natural color Chinese freshwater pearls should be stored in a darkened environment in order to preserve the natural pastel color, since they may fade with long exposure to sunlight.

Anyway, there are equally good pearls!
