Physical properties
Hardness of 7 on the Mohs scale, translucent pale green color, vitreous luster, hexagonal crystal system, and conchoidal fracture with no true cleavage.
Formation & geological history
Forms in hydrothermal veins, pegmatites, and metamorphic environments through the precipitation of silica-rich solutions over millions of years.
Uses & applications
Used in jewelry, decorative carvings, and as a polished collector's tumbled stone.
Geological facts
Green coloration in quartz is frequently caused by microscopic inclusions of minerals like actinolite, chlorite, or green tourmaline.
Field identification & locations
Identified by its high hardness (scratches glass), conchoidal fracture, and characteristic green hue; commonly sourced from Brazil, Madagascar, and the USA.
