Oyster Pearl Nacre at Walter Hyatt blog

Oyster Pearl Nacre. The nacre forms layers around the foreign object, gradually building up into a pearl. Small irritants are then inserted under the mantle and the nacre tissue begins forming a pearl. a pearl forms inside an oyster by a natural process in which the oyster secretes layers of nacre that wrap around a foreign object, or, in the case of cultured pearls, a nucleus that has been inserted specifically for the purpose of cultivating a pearl. to create a cultured pearl, the harvester opens the oyster shell and cuts a small slit in the mantle tissue. Nacre is created by alternating layers. the oyster’s immune system responds by secreting a material called nacre, which is made up of calcium carbonate crystals. for centuries, researchers have puzzled over how oysters grow stunningly symmetrical, perfectly round pearls around irregularly shaped grains of sand or bits of debris. but oysters can, and that’s because their pearls are built from nacre —aptly known as mother of pearl. the oyster or mussel slowly secretes layers of aragonite and conchiolin, materials that also make up its shell.
