Physical properties
Hardness: 7 (Mohs); Color: Pale pink to rose red; Luster: Vitreous to greasy; Crystal Structure: Trigonal (hexagonal); Cleavage: Indistinct; Specific Gravity: 2.65
Formation & geological history
Formed in pegmatites, hydrothermal veins, and occasionally igneous rocks. Its color is derived from microscopic inclusions of aligned silicate mineral fibers.
Uses & applications
Primarily used in jewelry making, ornamental carvings, beads, and as a popular specimen for crystal collecting and lapidary arts.
Geological facts
Unlike regular quartz, rose quartz rarely forms well-defined external crystals, instead appearing in massive form. When cut into cabochons, some specimens exhibit asterism (a star-like effect).
Field identification & locations
Identify by its characteristic hazy pink transparency and hardness. Common locations include Brazil, South Africa, India, and Madagascar. It is the pink variety of translucent quartz.
