Physical properties

Hardness of 7 on the Mohs scale, greenish color due to inclusions, vitreous luster, trigonal crystal system, conchoidal fracture with no true cleavage, specific gravity of 2.65.

Formation & geological history

Formed in hydrothermal veins and pegmatites, often colored by inclusions of minerals such as chlorite, actinolite, or fuchsite.

Uses & applications

Used in jewelry, decorative items, and crystal collections.

Geological facts

Green quartz is sometimes marketed commercially under the trade name 'prasiolite', though true prasiolite is typically heat-treated amethyst.

Field identification & locations

Identified by its green color, conchoidal fracture, and characteristic quartz hardness. Found worldwide in silica-rich environments.
