Physical properties
Hardness of 7 on Mohs scale, vibrant green color due to inclusions, vitreous luster, hexagonal crystal system, no cleavage.
Formation & geological history
Formed in hydrothermal veins or pegmatites where silica-rich fluids cooled over time with trace mineral inclusions.
Uses & applications
Used primarily in jewelry, lapidary arts, and mineral collecting.
Geological facts
Green quartz is often naturally irradiated or heated, and green varieties containing actinolite inclusions are sometimes traded as prasiolite.
Field identification & locations
Identified by its distinct green hue, hard crystal structure, and lack of cleavage; commonly sourced from Brazil, Madagascar, and the USA.
