Are freshwater pearls real pearls?
These pearls are grown in freshwater lakes, rivers, and ponds, predominately in China. … Many freshwater pearls don't have a bead nucleus — only a piece of tissue — resulting in a pearl with thicker nacre than the akoya.

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?
A natural pearl begins its life inside an oyster's shell when an intruder, such as a grain of sand or bit of floating food, slips in between one of the two shells of the oyster, a type of mollusk, and the protective layer that covers the mollusk's organs, called the mantle.
Are there different types of pearls?

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.
