A 10mm white, golden, or silver shell pearl on each end of this open ring made in 950 sterling silver with gold or rhodium plating.

Shell pearls, also known as mother-of-pearl pearls or South Sea pearls, are produced from the inner shell of some species of mollusks, such as abalone and oyster. This inner layer is composed of nacre, the same material that is found in natural pearls.

Unlike cultured pearls, which are produced by inserting an irritant substance inside the mollusk, shell pearls are naturally formed as a protective layer of the mollusk shell against possible external aggressions, such as parasites and grains of sand.

Shell pearls come in a wide variety of colors, sizes, and shapes, depending on the species of mollusk they come from and the conditions under which they were produced. Because they are produced naturally, these pearls are considered a more affordable option than cultured and natural pearls. However, they can still have great aesthetic value and be highly prized in jewelry.
