Physical properties
Hardness 7 Mohs; pale pink, translucent-to-opaque appearance; vitreous luster when polished; trigonal crystal structure; no cleavage, conchoidal fracture. The visible dark veining may be inclusions or surface fractures, and the object is carved and polished.
Formation & geological history
Rose quartz forms mainly in granitic pegmatites and hydrothermal veins, commonly as massive quartz rather than well-formed crystals. Its age depends on the host rock, often Precambrian to younger; carving and polishing are modern human processing.
Uses & applications
Used as an ornamental stone, décor, meditation material, and occasionally in jewelry. Comparable carved bowls commonly sell for about $20–$100, with larger, cleaner, strongly colored pieces costing more.
Geological facts
The pink color is generally linked to microscopic inclusions of minerals such as dumortierite or related trace components; it is not usually caused by manganese alone. Rose quartz can fade somewhat with prolonged intense sunlight or heat.
Field identification & locations
Identify by its glassy polish, hardness, quartz-like conchoidal fractures, and inability to scratch with a steel knife while potentially scratching glass. Common sources include Brazil, Madagascar, India, South Africa, and the United States; value range: approximately $15–$100 for this type of bowl.
