Physical properties
Hardness: 7 Mohs; Color: Forest green with silvery-green shimmer; Luster: Vitreous to waxy; Crystal Structure: Trigonal/Hexagonal; Cleavage: None/Conchoidal fracture; Specific Gravity: 2.64-2.69.
Formation & geological history
Formed in metamorphic environments where quartz-rich sediments are subjected to heat and pressure, allowing chromium-rich fuchsite mica to crystallize within the quartz matrix.
Uses & applications
Commonly used for lapidary work, decorative figurines, tumbled stones for metaphysical use, and cabochons for jewelry.
Geological facts
The shimmering effect seen in this stone is called aventurescence, caused by light reflecting off tiny plates of mica within the stone.
Field identification & locations
Identify by its characteristic 'speckled' or 'shimmery' green appearance under light. It is commonly found in India, Brazil, and Russia. Collectors value it for its vibrant green hue and sparkly inclusions.
