Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, hexagonal crystal system, conchoidal fracture, and specific gravity around 2.65.
Formation & geological history
Forms in hydrothermal veins and pegmatites through the cooling of silica-rich solutions over millions of years.
Uses & applications
Used in gemstone jewelry, ornamental carvings, lapidary arts, and mineral collecting.
Geological facts
Green coloration typically results from microscopic inclusions of minerals like fuchsite or chlorite within the quartz matrix.
Field identification & locations
Identified by its green hue, high hardness, and lack of cleavage; commonly sourced from localities in Brazil, India, and the USA.
