Physical properties
The specimen appears translucent to opaque pinkish-brown with a glassy to uneven surface. Quartz has Mohs hardness 7, a trigonal crystal structure, no cleavage, and conchoidal fracture; the photo alone cannot confirm the identification.
Formation & geological history
Rose quartz forms in silica-rich pegmatites and hydrothermal veins, commonly crystallizing during late-stage cooling of granitic magma. Its age depends on the deposit and may range from millions to billions of years.
Uses & applications
Used for beads, carvings, decorative stone, and inexpensive jewelry; rough pieces are also collected.
Geological facts
Quartz is one of Earth’s most abundant minerals. Rose coloration is associated with trace elements or microscopic inclusions, depending on the variety.
Field identification & locations
Look for glassy luster, hardness sufficient to scratch glass, and lack of cleavage; pink quartz is found in pegmatites worldwide, including Brazil, Madagascar, and the United States. The pictured piece is too small and obscured for confident identification.
