Physical properties
Hardness of 2 to 2.5 on the Mohs scale, vibrant emerald-green color due to chromium, pearly to vitreous luster, and monoclinic crystal system with perfect basal cleavage.
Formation & geological history
Formed in metamorphic rocks, specifically quartz-chlorite-mica schists, through hydrothermal alteration and regional metamorphism.
Uses & applications
Used primarily as an ornamental stone, carved into figurines, or collected by mineral enthusiasts for its sparkling green appearance.
Geological facts
Fuchsite is a chromium-rich variety of muscovite. It often sparkles intensely due to its fine-grained micaceous flakes.
Field identification & locations
Easily identified by its distinctive emerald-green color and micaceous flake cleavage. Commonly found in Brazil, India, Russia, and the USA.
