Quartz, silicon dioxide (SiO₂), likely rose quartz

AI-generated identification · may be incorrect

Pale salmon-pink, translucent to opaque, with a vitreous luster and irregular conchoidal fracture; hardness 7 on the Mohs scale, no cleavage, and specific gravity about 2.65. The rounded surface suggests tumbling or polishing.

Physical properties

Formation & geological history

Rose quartz forms mainly in silica-rich pegmatites and hydrothermal veins, with its color commonly caused by microscopic inclusions of dumortierite or related minerals. It occurs in Precambrian crystalline terrains, though the specimen’s exact age and locality cannot be determined from the image.

Uses & applications

Used as an ornamental stone, beads, carvings, and inexpensive jewelry; polished pieces are popular among mineral collectors. It has little industrial value compared with ordinary quartz.

Geological facts

Rose quartz commonly has a cloudy, homogeneous pink appearance rather than distinct crystals. Natural pink quartz is often confused with dyed quartz, pink calcite, or glass.

Field identification & locations

Likely quartz if it scratches glass and does not react with dilute acid; calcite would fizz and is much softer. Common sources include Brazil, Madagascar, India, and South Africa.
