Physical properties

Mohs hardness of 7, reddish-orange color due to hematite inclusions, vitreous luster, hexagonal crystal system, and conchoidal fracture.

Formation & geological history

Formed in hydrothermal veins and pegmatites through the crystallization of silica-rich solutions over millions of years.

Uses & applications

Used in crystal collections, jewelry, lapidary arts, and decorative items.

Geological facts

The distinct red coloration comes from tiny trapped particles of iron oxide or hematite dispersed within the quartz matrix.

Field identification & locations

Easily identified by its hardness, lack of cleavage, and characteristic reddish hue; found globally in quartz-bearing rock formations.
