Physical properties
Typically Mohs hardness 7, pale pink to salmon color, vitreous luster, massive rather than visibly crystalline, with indistinct cleavage and conchoidal fracture; density about 2.65 g/cm³. The pictured piece appears rough and naturally fractured, though identification from the image is uncertain.
Formation & geological history
Forms mainly in silica-rich pegmatites and hydrothermal veins, with its pink color commonly linked to microscopic inclusions or trace elements. It occurs in Precambrian and younger granitic environments.
Uses & applications
Used as ornamental stone, carvings, beads, tumbled stones, and occasional cabochons; transparent gem-quality material is uncommon. Common specimens have modest commercial value.
Geological facts
Rose quartz often shows a cloudy, translucent appearance rather than the sharp crystals typical of rock crystal. Star effects can appear after polishing when microscopic inclusions are aligned.
Field identification & locations
Identify by its pink color, glassy fracture, hardness, and inability to scratch it with a steel knife; it should scratch ordinary glass. Common localities include Brazil, Madagascar, South Africa, India, and the United States.
