Physical properties
Hardness of 7 on the Mohs scale, milky white to translucent color, vitreous to greasy luster, trigonal crystal system, conchoidal fracture with no true cleavage, specific gravity of 2.65.
Formation & geological history
Formed through the cooling and crystallization of silica-rich hydrothermal solutions within veins and pegmatites across various geological eras.
Uses & applications
Used in glassmaking, abrasives, electronics, ornamental items, and mineral collecting.
Geological facts
Milky quartz is the most common variety of the quartz family and gets its cloudy appearance from microscopic fluid or gas inclusions trapped during crystal growth.
Field identification & locations
Easily identified in the field by its distinct white color, lack of cleavage, and high hardness that scratches glass. Found worldwide in nearly all geological environments.
