PEARL
Composition
An organic gem formed inside the shells of mollusks. Composed of layers of aragonite and an organic substance called conchiolin that gradually accumulate around a grain of sand or another microscopic nucleus.
Color
White, milky, cream, pink, grey, gold, and black. The pearl's glow (orient) appears due to the finest layers of aragonite, which reflect and refract light, creating a soft inner glow and depth of color.
Hardness
2.5-4.5 on the Mohs scale. A fairly soft material that requires particularly careful care.
Deposits
Japan, China, Thailand, the Philippines, Indonesia, Australia, French Polynesia
