Physical properties
Hardness: 2-2.5 on the Mohs scale, Color: Light green to emerald green, Luster: Vitreous to pearly, Crystal structure: Monoclinic (mica group), Cleavage: Perfect basal cleavage, Specific Gravity: 2.7-3.1
Formation & geological history
Formed in metamorphic environments, particularly in chromium-rich schists and hydrothermal veins.
Uses & applications
Used in ornamental carvings, gemstone jewelry, and as a collector's mineral specimen.
Geological facts
Fuchsite is a chromium-rich variety of muscovite. Its distinctive sparkly green color is due to the presence of chromium substituting for aluminum.
Field identification & locations
Identified by its characteristic micaceous cleavage, flaky appearance, and bright green color. Commonly found in Brazil, Russia, India, and the USA.
