Physical properties
Hardness 7 Mohs; pale pink to lilac color, vitreous luster, translucent appearance, and conchoidal fracture. Quartz is trigonal and lacks cleavage; the specimen appears rough-cut or naturally fractured, with uncertainty from the image.
Formation & geological history
Forms in silica-rich igneous and hydrothermal veins, pegmatites, and metamorphic rocks. Rose quartz commonly develops as massive material rather than well-formed crystals; age depends on its host deposit.
Uses & applications
Used as a lapidary, ornamental, and collectible stone; higher-quality transparent pieces may be cut as gemstones, though most rose quartz is inexpensive.
Geological facts
Pink coloration may result from microscopic inclusions or trace-element defects. The adjacent gray rounded object may be another stone, but it is not identifiable confidently from this image.
Field identification & locations
Identify by its pink color, glassy luster, hardness, and lack of cleavage; it should scratch glass but not be scratched by a steel knife. Common sources include Brazil, Madagascar, India, and the United States.
