Physical properties

Formation & geological history

Commonly forms in hydrothermal veins and pegmatites. This specimen likely weathered out of a vein where groundwater enriched with iron oxides seeped into the micro-fissures, creating the orange-brown staining.

Uses & applications

Used in glass manufacturing, electronics (piezoelectric properties), abrasives, and as a semi-precious gemstone in jewelry and metaphysical collecting.

Geological facts

Quartz is one of the most abundant minerals in Earth's continental crust. Iron-stained quartz is often called 'Golden Healer' in metaphysical communities.

Field identification & locations

Identify by its hardness (it will scratch glass) and lack of cleavage. Look for it in river beds, mountainous regions, and garden gravels where it resists weathering.
