Pearl

A pearl is a hard, lustrous spherical mass, typically white or bluish-gray, formed within the shell of a pearl oyster or other bivalve mollusk.

Part of speech: noun
Definition: Pearls are organic gemstones that are formed when a mollusk produces layers of nacre around some type of irritant inside its shell. Unlike other gemstones that are mined from the earth, pearls are unique as they are cultivated within living creatures. The process can take several years, making pearls a prized item for their beauty and rarity. The value of a pearl is judged based on its luster, color, size, lack of surface flaw, and symmetry. These factors contribute to the elegance and allure of pearl jewelry, making it a timeless choice for adornments ranging from necklaces and bracelets to earrings and rings. Pearls come in various colors, including white, black, pink, and golden, depending on the type of mollusk and its environment, offering a wide range of options for personal adornment.
