Description

A pale green, opaque Microcline mineral. Amazonite derives its color from traces of lead and crystalline water (Aston et al 2000). Also called Amazon stone, it was used since about 3000 BCE for decorations, amulets, vessels, beads, and as a gemstone. Ancient examples have been found in Egypt, Mesopotamia, and northern India. Amazonite was considered one of the six most precious stones in Pharaonic Egypt. It is currently quarried in Russia and the U.S.(Colorado, Pennsylvania, Virgina).
