A pearl is created by the oyster, a perfectly natural process and has been so since long before pearls were cultured. The oyster is trying to encapsulate an irritant, either a parasitic intruder (in the case of natural pearls, or a mother-of-pearl sphere inserted into the oyster's gonad (in the case of cultured pearls). The oyster 'cultures' the pearl by surrounding the irritant with CaCO3- heavy seawater until the calcium carbonate (limestone, chalk and seashell) condenses on it. If you have a wealthy Chemistry department, you can tease apart the regularly formed crystalline structure of the layers of calcium carbonate, or, to a jeweller, 'nacre'. The heart of a saltwater cultured pearl is a mother-of-pearl bead, but the deposit is completely regular layered scales of calcium carbonate. Therefore, yes, a pearl is most definitely a mineral, and also a semi-precious stone.

A pearl might have a mineral at it's heart, but the outside of a pearl is a hardened substance called nacre that the mollusk secretes around a parasite that invades the mantle tissue.
Pearl is made of calcium carbonate with organic material (nacre) and water.
A pearl is not mineral. The five characteristics a mineral must have is that it must be solid, it has to have a chemical composition, it has to be inorganic, and it has to be naturally made, also it has to have a definite crystalline structure. The pearl contains chemicals within it so it has a chemical composition. It is inorganic of course (it isn't made of any remains or organic substances). It is not naturally made, however, making it not a mineral. Another reason it isn't a mineral is because of its shape. Minerals must have a definite crystalline structure, but a pearl is round, marking off the structure it must have to qualify to be a mineral. It also is quite obviously solid.
Pearl is the only birthstone that is not a mineral; it is an organic gemstone formed within shelled mollusks such as oysters and mussels. Its unique formation process sets it apart from other birthstones which are typically minerals.
Glass would not be considered a mineral because it is not naturally occurring and does not have a crystalline structure.
Opal, amber, and obsidian are three examples of mineraloids. Mineraloids are naturally occurring materials that lack a crystalline structure but have physical and chemical properties that resemble minerals.
Ice in a glacier is considered a mineral because it has a crystalline structure and forms through natural processes, meeting the criteria to be classified as a mineral. However, the material that forms a glacier, such as snow, does not have a defined crystal structure and does not meet the criteria to be classified as a mineral.
Ice in a glacier is considered a mineral because it has a crystalline structure and forms through natural geological processes. Water from a glacier is not considered a mineral because it lacks a crystalline structure and is in a liquid state rather than a solid state.
a mineral
No, it is a mineral
A pearl would be composed of carbonate minerals.
Pearl??
Because they're considered pretty and used for jewelry. However, minerals are formed from geological processes, meaning pressures and heat in the ground. Pearls are made from clams.
some examples of a non-mineral is water pearl coal
calcium carbonate

Quartz is a mineral.
Water as a solid, in the form of ice, is considered a mineral when it is naturally occurring. Ice in snow banks is considered a mineral but ice cubes you make in your freezer are not a mineral.
Glass would not be considered a mineral because it is not naturally occurring and does not have a crystalline structure.
