Physical properties
Mohs hardness 7; pale pink, translucent to opaque, vitreous luster, typically massive rather than visibly crystalline, with conchoidal fracture and no cleavage. The smooth shape indicates tumbling and polishing.
Formation & geological history
Forms mainly in granitic pegmatites and hydrothermal quartz veins during cooling of silica-rich magmas; specimens may range from Precambrian to younger geological ages. The exact origin cannot be determined from the image.
Uses & applications
Used for carvings, ornaments, cabochons, beads, and inexpensive jewelry; quartz is also important industrially in glass, ceramics, and electronics.
Geological facts
Rose quartz commonly displays a soft pink color and is usually less transparent than crystalline quartz varieties. Asterism can occur in strongly fibrous material when cut as a cabochon.
Field identification & locations
Common sources include Brazil, Madagascar, India, South Africa, and the United States. Confirm with a hardness test against glass and inspect for natural internal inclusions; dyed glass or ceramic imitations are possible.
