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.
