No but they are the source (clams)

They can be found almost any shelled mollusk such as the pearl oyster
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.
What is the middle of a pearl?
The middle of a pearl is called the nucleus, which is typically a small, round object made of calcium carbonate or an organic material around which the pearl forms. As an irritant, it triggers the oyster or mollusk to secrete layers of nacre, or mother-of-pearl, which gradually builds up around the nucleus, creating the pearl's lustrous surface. The composition and structure of the nucleus significantly influence the pearl's size, shape, and overall quality.
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.
How is the quality of the pearl?
this pearl is judged by its thickness and the amount that you can get out of it
