Physical properties
White to colorless, translucent, with a sparkling vitreous luster and hexagonal crystal structure; Mohs hardness 7, no cleavage, specific gravity about 2.65. The image suggests a cluster of fine quartz crystals, though exact identification cannot be confirmed visually.
Formation & geological history
Quartz commonly crystallizes from silica-rich fluids in cavities and fractures, sometimes forming a fine drusy surface; quartz deposits range from ancient to geologically recent.
Uses & applications
Used for mineral collecting, decoration, and occasionally in jewelry; quartz is also widely used in glass, electronics, and industrial abrasives.
Geological facts
Quartz is one of Earth’s most abundant minerals and occurs in many colors and crystal habits.
Field identification & locations
Look for a glittering surface made of many tiny, hard crystals; quartz scratches glass and is not scratched easily by a steel knife. Found worldwide in veins, geodes, and cavities.
