Physical properties
Hardness of 7 on the Mohs scale, yellow to golden color, vitreous luster, hexagonal crystal system, conchoidal fracture, and specific gravity of 2.65.
Formation & geological history
Formed in hydrothermal veins and pegmatites through the precipitation of silica-rich solutions under high temperature and pressure.
Uses & applications
Used in jewelry, ornamental carvings, glassmaking, and electronics due to its piezoelectric properties.
Geological facts
Yellow coloration is typically caused by natural irradiation or sub-microscopic inclusions of iron oxide or hydroxide within the silica matrix.
Field identification & locations
Identified by its high hardness, inability to be scratched by steel, and lack of cleavage. Found worldwide in quartz-bearing rocks.
