What are marine pearls?


Layer upon layer of nacre, also known as mother-of-pearl, coat the grain of sanduntil the iridescent gem is formed. Cultured pearls are made in the same way. The only difference is that instead of accidental circumstances, a "pearl farmer" embeds a grain of sand into the mollusk.Nov 20, 2012
What are marine pearls?

Marine Pearls. ... Humans have long harvested these and other marine mollusks for their mother-of-pearl shells and natural pearls. Today many species of mollusks are raised in pearl culturing, also called "perliculture," producing cultured pearls in a wide range of shapes, sizes and colors.


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.
