Tumbled pink quartz (probable rose quartz)

Quartz, silicon dioxide (SiO₂), likely rose quartz variety

AI-generated identification · may be incorrect

Small rounded, polished pebble with pale salmon-pink color and a dull to vitreous luster. Quartz has hardness 7, no cleavage, conchoidal fracture, trigonal crystal structure, and specific gravity about 2.65; the image cannot confirm translucency or composition.

Physical properties

Formation & geological history

Rose quartz forms mainly in granitic pegmatites and hydrothermal veins, with its color commonly related to microscopic inclusions of dumortierite or other minerals. The specimen was likely mechanically tumbled; its geological age depends on its source rock, commonly Precambrian to younger.

Uses & applications

Used for carvings, beads, cabochons, ornamental objects, and inexpensive crystal specimens. Common tumbled pieces typically have modest market value.

Geological facts

True rose quartz is usually cloudy and massive rather than forming well-developed crystals. Similar pink materials include dyed quartz, pink feldspar, calcite, and glass, so visual identification alone is provisional.

Field identification & locations

Commonly found in Brazil, Madagascar, India, South Africa, and the United States. Test with a steel file or glass cautiously: quartz should scratch glass and resist a steel blade; a streak test, loupe, and hardness comparison help distinguish calcite or glass.
