Physical properties
Hardness of 7 on the Mohs scale, pale green color, vitreous luster, hexagonal crystal system, and conchoidal fracture.
Formation & geological history
Forms in hydrothermal veins and pegmatites through the deposition of silica-rich fluids under high pressure and temperature.
Uses & applications
Used primarily in lapidary work, ornamental carvings, and crystal collections.
Geological facts
Green coloration is typically caused by microscopic inclusions of minerals like chlorite, actinolite, or green tourmaline.
Field identification & locations
Identified by its distinct hardness, lack of cleavage, and light green hue; commonly found in quartz-rich metamorphic and igneous terrains.
