Physical properties
Pale pink, translucent to nearly transparent, with a vitreous luster and uneven fracture; Mohs hardness 7, no cleavage, and specific gravity about 2.65. The rough, granular surface may indicate a natural quartz fragment or lightly processed specimen.
Formation & geological history
Forms mainly in silica-rich pegmatites and hydrothermal veins, commonly during Precambrian to Phanerozoic continental-crust events. Pink color usually results from microscopic inclusions or trace elements such as titanium, iron, or manganese.
Uses & applications
Used for carvings, beads, cabochons, ornamental objects, and inexpensive gemstone specimens; massive rose quartz is also used decoratively. It is not generally valuable as a faceting material because it is often cloudy.
Geological facts
Rose quartz commonly lacks well-formed crystal faces and is usually massive. Asterism can occur in some polished specimens due to aligned microscopic inclusions.
Field identification & locations
Identify by its pink color, glassy appearance, hardness, and inability to scratch with a steel knife; it should scratch glass, though testing can damage the specimen. Common sources include Brazil, Madagascar, India, South Africa, and the United States.
