Pearls are an organic gem, created when an oyster covers a foreign object with beautiful layers of nacre . It is a highly valued gem. The more perfect the shape of the pearl (spherical or drop like) and the deeper its lustre, the greater its value.

The best pearls are usually white, sometimes with a creamy or pinkish tinge, but may be tinted with yellow, green, blue, brown, or black. Black pearls, because of their rarity, are often highly valued.

Freshwater pearls occur in mussels, when foreign material, usually a sharp object or parasite, enters a mussel and cannot be expelled. To reduce irritation, the mollusk coats the intruder with the same secretion it uses for shell-building, nacre.

Pearls are not cut or polished like other gems. They are very soft and are injured by acids and heat; as organic products, they are subject to decay.
