Amazonite is a translucent to opaque microcline feldspar composed of potassium aluminum silicate. Amazointe, also known as Amazon Stone, ranges in color from blue-green to green. It's an opaque stone often found with white, yellow, or gray inclusions and a silky luster or a silvery sheen. Mohs hardness 6-6.5.

Amazonite was named after South America's Amazon River, which flows through Brazil. However, mineralogists claim that no green despoits of feldspar exist in this region. Amazonite and other green feldspars does occur naturally in other areas of Brazil but not in the Amazon River. Amazonite is associated with deposits of granite and quartz and is found in parts of Colorado, USA, Norway, Canada, Russia, India, Madagascar, Nambia and Tanzania. The coloration varies from light green to a darker ''emerald'' green, depending on the region it comes from.
