Physical properties

Formation & geological history

Forms from hydrothermal solutions or cooling magma in veins and pegmatites. The iron staining occurs when the quartz is exposed to oxygen and moisture, causing iron minerals to oxidize on the surface or within fractures.

Uses & applications

Used in glassmaking, electronics (piezoelectric properties), abrasives, and as decorative garden stones or metaphysical specimens.

Geological facts

Quartz is the second most abundant mineral in Earth's continental crust. Stained specimens like this are often referred to as 'Golden Healer' in metaphysical circles.

Field identification & locations

Identify in the field by its hardness (it can scratch glass), lack of cleavage, and resistance to weathering. Commonly found in mountainous regions or creek beds worldwide.
