Physical properties
Hardness 7 Mohs; salmon-pink to mauve color, vitreous-to-waxy luster, translucent to opaque, and no prominent cleavage. The rounded, smooth surface indicates mechanical tumbling; inclusions or staining may cause uneven color.
Formation & geological history
Rose quartz forms mainly in hydrothermal veins and granitic pegmatites, with pink color associated with microscopic inclusions and trace elements. Most specimens are Precambrian to younger quartz-bearing material, then cut and polished for sale.
Uses & applications
Used as an ornamental stone, paperweight, cabochon, bead, and metaphysical collectible; quartz is also important industrially in glass, electronics, and abrasives.
Geological facts
The specimen appears to rest on a coarse granite or pegmatite matrix containing abundant white quartz, feldspar, and dark minerals. True rose quartz commonly has a cloudy, even pink tone rather than distinct crystals.
Field identification & locations
Identify by its pink color, glassy feel, lack of cleavage, and ability to scratch ordinary glass; a steel blade should not scratch it easily. Common sources include Brazil, Madagascar, India, and the United States.
