AMAZONITE derives its name from the Amazon River, however it is doubtful that the stone occurs in that region. It is a green to blue-green variety of Microcline, a feldspar mineral. Amazonite is used in jewelry, where it is usually cut into a cabochon form. It is also quite lovely used in carved objects. Because of its color and texture it is sometimes mistaken for jade.

The color of AMAZONITE varies from green, yellow-green to blue-green, and in some gemstones demonstrates white streaks. Colorado is a well-known locality for crystals of amazonite, and it is also found in Madagascar and Brazil.
