Physical properties
Hardness of 7 on the Mohs scale. Color is primarily white to clear with reddish-brown iron oxide staining. Luster is vitreous to sparkling druzy. Crystal system is trigonal. No distinct cleavage, exhibits conchoidal fracture. Specific gravity is 2.65.
Formation & geological history
Formed through hydrothermal processes where silica-rich fluids circulated through cavities in host rock, depositing microscopic quartz crystals along the walls to form a druzy crust.
Uses & applications
Used in ornamental display, mineral collecting, and occasionally crafted into unique jewelry pieces.
Geological facts
Druzy quartz forms when miniature crystals grow on a parent rock, creating a sugar-like glittering texture that catches light from many angles.
Field identification & locations
Can be identified by its characteristic sparkling micro-crystalline surface (druzy) and hardness that scratches glass. Found worldwide in areas with volcanic or hydrothermal activity.
