Amazonite
Amazonite is a striking variety of feldspar known for its distinctive blue-green colour. The stone is named after the Amazon, although there are no known deposits in that area. The colour ranges from soft turquoise to deep greenish blue and is caused by the presence of lead and water in the crystal structure. Often amazonite has a slightly striped or mottled pattern, which contributes to its unique appearance.
Major sources of amazonite include Brazil, Madagascar, Russia, China and the United States. The clearest and most intensely coloured specimens often come from Colorado and Madagascar. Geologically speaking, amazonite forms in pegmatites, coarse-grained igneous rocks rich in minerals. The chemical formula of amazonite is K(AlSi₃O₈), and it belongs to the microcline feldspar group. It has a hardness of 6 to 6.5 on the Mohs scale.
