"Nacre" is not a type of pearl, but rather the material coating that creates a pearl.
A pearl is made up of layers and layers of a substance called nacre -- calcium carbonate and protein. The thicker the nacre is, the more durable and valuable the pearl. The average thickness of a cultured pearl's nacre ranges from 1mm to 3mm.
"Nacre" is a pearly substance that mollusks secrete around irritants. Thick, overlapping nacre layers create a strong luster and a valuable pearl. Thick nacre layers take years to build up. It can be used to determine whether a pearl is real.

What is nacre commonly known as?
Mother of Pearl
What is the scientific name for Mother of Pearl?

What is the name of the substance that the oyster produces to create a pearl?
Nacre
How thick is the nacre?
The thickness of nacre, which is also known as mother-of-pearl, can vary depending on the type of mollusk it comes from. Typically, nacre can range from around 0.3 millimeters to 3 millimeters in thickness.

What is the name of the substance inside a mullusk shell that makes and protects the pearl?
Nacre
How pearl is being produce?
Pearl is produced by an oyster to protect itself from something that got inside its shell. It secretes nacre, which becomes pearl. Cultured pearls are made by placing a "seed" inside of the oyster shell, and letting the oyster work. Over time, the oyster will deposit nacre onto the seed, forming a pearl.
A particle trapped between the mantle and shell of bivalves becomes covered with and eventually a is formed?
Nacre, pearl
Where did pearl diving take place?
refers to a now largely obsolete method of retrieving pearls from pearl oysters, freshwater pearl mussels and, on rare occasions, other nacre-producing creatures, such as abalone. refers to a now largely obsolete method of retrieving pearls from pearl oysters, freshwater pearl mussels and, on rare occasions, other nacre-producing creatures, such as abalone.
How do oysters form pearls?
­The formation of a natural pearl begins when a foreign substance slips into the oyster between the mantle and the shell, which irritate­s the mantle. The man­tle covers the irritant with layers of the same nacre substance that is used to create the shell. This eventually forms a pearl. So a pearl is a foreign substance covered with layers of nacre. Cultured pearls are created by the same process as natural pearls, with a slight nudge by pearl harvesters. To create a cultured pearl, the harvester opens the oyster shell and cuts a small slit in the mantle tissue. Cutting the mantle is enough to induce the nacre secretion that produces a pearl -- an irritant doesn't have to be inserted. While cultured and natural pearls are considered to be of equal quality, cultured pearls
Scientific name of mother of pearl?
The scientific name for mother of pearl is nacre, which is a composite material produced by some mollusks as an inner shell layer. It is composed of calcium carbonate and organic proteins, giving it its iridescent appearance.
