How are freshwater pearls made?
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.
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 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".

What is a baroque cultured pearl?
Baroque pearls are pearls with an irregular non-spherical shape. … Most cultured freshwater pearls are baroque because freshwater pearls are mantle-tissue nucleated instead of bead nucleated. Cultured saltwater pearls can also be baroque, but tend to be more teardrop-shaped due to the use of a spherical nucleation bead.
How are pearls farmed?
An oyster makes pearls on its own by secreting nacre, or mother of pearl, around an irritant that gets into its shell. … At oyster farms, when the mollusks are large enough, a worker carefully pries open the shell and inserts a small nucleus, or bead, as well as a piece of mantle cut from another pearl oyster.
What is nacre made of?
Nacre is composed of hexagonal platelets of aragonite (a form of calcium carbonate) 10–20 µm wide and 0.5 µm thick arranged in a continuous parallel lamina.
