About: Amazonite Gemstone
Amazonite is the pale green to the bluish variety that is green of which is an associate of the Feldspar band of minerals that also includes Albite, Andesine, Anorthite, Bytownite, Hyalophane, Labradorite, Moonstone, Oligoclase, Orthoclase, Sanidine and Sunstone. The colour of Amazonite is generally caused by a higher lead (Pb) content of as much as 1.2% PbO. However, there are also indications that the colour that is green of Microcline is brought on by divalent Fe (Szuzkiewicz & Kerber, 2010). Amazonite is available in tones of pale green to dark green, aqua bluish and green.
A few of the most beautiful crystals that are amazonite result from the Pike’s Peak and Crystal Peak areas of Colorado, USA. Amazonite from Colorado has now been called the greatest specimens in the world for many years but a find that is new of crystals from Konso, Sidamo-Borana Province, Ethiopia are said to equal if not surpass the crystals from Colorado. The colour of those Ethiopian crystals is a turquoise that is intense with outstanding lustre.
Amazonite is practically always opaque and makes for beautifully coloured cabochons. A find in Mogok, Myanmar (Burma) has produced a number that is tiny of rare transparent crystals which were faceted into gems. Another current find in Vietnam has produced green that is vivid that have been faceted into stunning gems of amazing clarity and colour.
Amazonite was cited in 1701 in French as Pierre des Amazones, meaning stone regarding the Amazon (discussing the river that is Amazon, by Nicolas Venette (1633-1698) in their TraitÃ© des Pierre (Treatise on Stones); although the title probably goes straight back further. It was cited once again in 1755 by Antoine-Joseph DÃ©zallier d’Argenville (1680-1765) under the name that is same his book L’Histoire Naturelle. The name was modified to “Amazonite” in 1847 by Johann Friedrich August Breithaupt (1791-1873) for a type that is unspecified near the Amazon River.
