The pearl is the only gemstone manufactured from a living organism, that is, it is the result of the defense system against external agents, which try to penetrate a shell. When trying to invade the oyster, grains of sand and other elements are covered by pearly calcium particles.

Amber is the name of the stones originated by the fossil resins found in trees and, therefore, it is considered of vegetal origin. With a yellowish hue, this gem is widely used in the manufacture of necklaces, bracelets, and earrings, in addition to being complements to some art objects.
