Physical properties
Hardness 7 on the Mohs scale, white to colorless quartz matrix with metallic yellow gold inclusions, vitreous luster.
Formation & geological history
Formed in hydrothermal veins via hot, mineral-rich fluids circulating through fractures in Earth's crust over millions of years.
Uses & applications
Primarily mined for bullion and precious metal extraction, as well as valued as a high-end mineral specimen for collectors.
Geological facts
Gold often forms in quartz reefs, creating striking contrast specimens known as mother lode quartz.
Field identification & locations
Identify by testing quartz hardness against glass and checking gold inclusions for high density and malleability; found globally in metamorphic and igneous terrains.
