Physical properties
Hardness of 7 on Mohs scale, white to translucent color, vitreous to greasy luster, hexagonal crystal system, conchoidal fracture with no true cleavage.
Formation & geological history
Formed through the crystallization of silica-rich hydrothermal solutions in veins and pegmatites across various geological eras.
Uses & applications
Used in glassmaking, abrasives, electronics, and as decorative lapidary material or mineral specimens.
Geological facts
Milky quartz is the most common variety of crystalline quartz, colored white by microscopic fluid inclusions trapped during growth.
Field identification & locations
Identified by its high hardness (scratches glass), white milky appearance, and conchoidal fracture. Found worldwide in virtually all geological environments.
