Physical properties

Hardness: 7 on Mohs scale; Color: Red to reddish-orange; Luster: Vitreous (glassy); Crystal Structure: Hexagonal (trigonal); Cleavage: None/Conchoidal fracture; Specific Gravity: 2.65

Formation & geological history

Forms through the crystallization of silica-rich hydrothermal fluids in cavities or fractures. The red pigmentation is caused by the presence of iron oxide (hematite) during or after the growth process.

Uses & applications

Primarily used in jewelry, as decorative collector specimens, and in metaphysical practices. Industrial quartz is used in electronics and glassmaking, though colored varieties are less common for industrial use.

Geological facts

The term 'druzy' refers to a coating of fine crystals on a rock surface. Red quartz is often associated with the concept of energy and vitality in various cultures. It is frequently found in geode form.

Field identification & locations

Identified by its crystal habit, high hardness (will scratch glass), and lack of cleavage. Often found in volcanic regions or sedimentary basins worldwide, notably in Morocco, Brazil, and the USA.
