Physical properties
Hardness of 7 on the Mohs scale, transparent to translucent green color, vitreous luster, and trigonal crystal structure.
Formation & geological history
Formed via hydrothermal veins and igneous pegmatites, often colored naturally by iron or mineral inclusions.
Uses & applications
Used primarily in fine jewelry, ornamental carvings, and metaphysical healing practices.
Geological facts
Green quartz is frequently marketed under trade names like prasiolite, though much of the commercial market consists of heat-treated amethyst.
Field identification & locations
Identified by its distinct conchoidal fracture, high scratch resistance, and hexagonal crystal habit.
