Are black pearls real?

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.

Just like the shell of a mollusk, a pearl is composed of calcium carbonate (mainly aragonite or a mixture of aragonite and calcite) in minute crystalline form, which has been deposited in concentric layers. The ideal pearl is perfectly round and smooth, but many other shapes, known as baroque pearls, can occur.
