Physical properties

Formation & geological history

Forms in hydrothermal veins, pegmatites, and sedimentary environments where silica-rich fluids precipitate or crystallize over millions of years.

Uses & applications

Used in jewelry, metaphysical healing, ornamental carvings, and glassmaking.

Geological facts

Yellow quartz is sometimes naturally irradiated or contains trace amounts of iron, giving it its distinct warm hue. It is closely related to citrine, though natural citrine is rarer.

Field identification & locations

Can be identified in the field by its hardness (scratches glass), lack of cleavage, and conchoidal fracture. Commonly found in river gravels, pegmatites, and quartz veins worldwide.
