Amazonite (Microcline Feldspar) is the blue-green variety of Microcline, a member of the Feldspar group. Sometimes referred to as Amazon Stone or Amazon Jade, it’s interesting to note that there are no known sources of this mineral in any of the Amazon’s jungles or rivers. Rather, the name Amazonite was used purely as a marketing tool. Well formed crystals of this Microcline variety are highly sought after by collectors – some of the most iconic and aesthetic specimens featuring Amazonite paired with Smoky Quartz are found in Colorado, USA. It is also associated with Albite, Cleavelandite, Quartz, Schorl, Fluorite and Topaz to name a few.
The crystal system for Amazonite (Microcline Feldspar) is triclinic, most often in prismatic crystals, which can be exceptionally large in size. Other forms include tabular, twinning, crystal clusters and massive.
