Physical properties
Hardness: 7 on Mohs scale; Color: Dull to dark green; Luster: Vitreous to waxy with 'aventurescence' (shimmer); Crystal structure: Trigonal; Specific Gravity: 2.64-2.69.
Formation & geological history
Formed primarily in metamorphic rocks like phyllites or schists where quartz recrystallizes in the presence of chromium-rich mica (fuchsite), which gives it the green color.
Uses & applications
Commonly used for ornamental carvings, figurines, beads for jewelry, and as a popular palm stone for crystal healing collectors.
Geological facts
The shimmering effect is called aventurescence, caused by tiny plate-like inclusions of green mica. The name comes from the Italian 'a ventura,' meaning 'by chance.'
Field identification & locations
Identify by its characteristic green color and internal metallic-looking sparkles under bright light. It is commonly found in India and Brazil.
