A market-wide average across qualities and sizes. Your stone's value depends on carat, color, clarity, cut, treatment, and origin.
Pearls are organic gems formed within mollusks, composed primarily of aragonite (calcium carbonate) platelets and conchiolin arranged in nacreous layers. They may be natural or cultured, freshwater or saltwater, and occur in a wide variety of sizes, shapes, colors and luster qualities. With Mohs hardness around 2.5–4.5 and good toughness in compact nacre, pearls are relatively soft and sensitive to acids, heat and dehydration.
