This pear shaped cabochon of Amazonite has gorgeous color with lots of "flash". Amazonite is a gem variety of microcline feldspar and is usually polished as a cabochon. It displays a schiller of light which is caused by inclusions. Schiller is a lustrous reflection from planes in a mineral grain and is similar to what is more commonly known as iridescence. The schiller is caused by a feature of the stone's crystal structure. Orthoclase feldspar and albite are present in close association, arranged in layers. This causes an interference effect of light. Amazonite, also known as 'Amazone stone,' is a light, aqua-green stone with white mottled flecks. The name, Amazonite, has been taken from the Amazon River, where formerly certain green stones were obtained, but it is found in Brazil. The origin of the stone is the New England States and Colorado. Amazonite is a mineral, but because of its lively green color, it is cut and polished as a gemstone. The green color of the stone has been attributed to the presence of copper. It can also be due to some organic pigment, probably an organic salt of iron, as it is removed by heat from the source.
