What makes a pearl?
Natural pearlsContrary to popular belief, a natural pearls is notformed by a grain of sand. This story is an urban legend.A natural pearl forms inside a bivalve mollusk when the shell has been invaded by a parasite or damaged. The most common reason a natural pearl will develop is due to parasitic invasion.The parasite wil burrow through the periostracum layer (outer layer) of a mollusk shell and into the mother-of-pearl beneath. When the parasite penetrates the mother of pearl in comes in contact with the mollusk's mantle muscle. This muscle contains cells known as epithelial cells. These cells produce a substance called nacre which coats the inside of the shell (mother-of-pearl) and is the substance of which a pearl is composed.The parasite becomes lodged in this mantle muscle and dies. The mollusk's definsive reaction is to grow a sac around the intruder. This sac is called the pearl sac. Once the sac encases the intruder the cells begin to deposit nacre- which is composed of aragonite and calcite (a calcium carbonate compound) platelets.Cultured PearlsCultured (marine) pearls are grown by inserting a rounded bead of mother-of-pearl and a piece of mantle tissue containing epithelial cells from a donor mollusk into the gonad, or reproductive organ, of a host mollusk. The donor tissue grows into a pearl sac around the bead. As in natural pearl production, this sac then deposits nacre.Maturity time of artificial oyester pearl
Which mollusk's shell is used as a building material?
Chinese high end furniture may contain mother of pearl inlays. This is the narce of a mollusk and is highly prized.
Is a pearl an element?
No it isn't. Pearl is a hard, generally spherical object produced within the soft tissue (specifically the mantle) of a living shelled mollusk. Just like the shell of a mollusk, a pearl is made up of calcium carbonate in minute crystalline form, which has been deposited in concentric layers.
Is a pearl a sedimentary rock?
No, pearls are gems produced by oysters, not rocks.

What is a pearl and how is it made?
A pearl is a hard, round object produced within the soft tissue of a living mollusk, typically an oyster or a mussel. It forms as a defense mechanism against irritants, such as a grain of sand, when the mollusk secretes layers of nacre, a substance made of calcium carbonate and conchiolin. Over time, these layers accumulate, resulting in the formation of a pearl. Natural pearls are rare, while cultured pearls are produced through human intervention by deliberately introducing an irritant into the mollusk.
What mollusk is capable of making a gem quality pearl?
Pearl oysters or also called marine bivalve molluscs. They are the only oyster to produce south sea pearls.
Is A turle a mollusk?
No, a turtle is a reptile.
How are pearls made?
Natural PearlsNatural pearls typically form when a parasite burrows through a mollusk's shell and into the mantle tissue. The mollusk's defensive reaction surrounds the intruder with a membrane known as a pearl sac. The interior of this sac is lined with nacre-producing cells known as epithelial cells. These cells begin to deposit microscopic platelets of nacre (aragonite and calcite) around the intruder. This continues and a pearl grows. Damage to the mollusk's shell has also been known to cause natural pearl formation. A grain of sand does NOT produce a pearl Cultured PearlsCultured pearls are produced by the introduction of a nucleus and a piece of donor-mollusk mantle tissue in the gonad of a marine mollusk (pearl oyster), or by grafting a piece of donor mantle tissue into a freshwater mussel's mantle (without a bead).
Is a bee a mollusk?
no a bee isn't a mollusk.
How does pearls get their colors?
Pearls get their color from the minerals and organic compounds present in the water where they are formed. Factors such as the type of mollusk creating the pearl, the environment, and any treatments applied can also influence the color of a pearl.
