Amazonite
Amazonite is a silicate mineral recognized among collectors for its crystal form and distribution, with notable Chinese occurrences.
About Amazonite
Amazonite is classified as a silicate mineral in the alkali feldspar group (microcline variety) and has the chemical formula K(AlSi3O8). It crystallizes in the triclinic system and holds a steady position among silicate species.
Identification & care
Crystals commonly develop as blocky prismatic crystals; twinned (grid-like perthite texture); massive, cleavable. Its color is typically blue-green to green, turquoise-blue and often with white perthitic streaks. The luster is vitreous, the streak is white, and specimens range from opaque to translucent. The cleavage is perfect on {001} and {010} at ~90° (feldspar cleavage). The fracture is uneven, which aids identification.
Collector context
Collector notes
Amazonite holds a steady place in systematic mineral collections. Documented Chinese occurrences are recorded at Xianghualing Sn-polymetallic ore field, among others.
