The interior shell, called the nacre, of most oysters is usually a glossy white or silver but the Tahitian black-lipped oyster features a thick band of black.
Where do real pearls come from?

Are cultured pearls real?
Natural pearls are formed by nature, more or less by chance. On the other hand, cultured pearls are human creations formed by inserting a tissue graft from a donor mollusk, upon which a pearl sac forms, and the inner side precipitates calcium carbonate, in the form of nacre or "mother-of-pearl".
How are freshwater pearls cultivated?
At freshwater pearl farms, each mussel is surgically implanted with 24 to 32 tiny pieces of mantle tissue, a process known as nucleation. Once the tissue has been inserted, a sac forms and cells begin secreting nacre (pronounced NAY-ker), forming a calcium-carbonate compound – a pearl.
