Rose quartz (rough specimen)
Quartz, SiO₂; pink variety commonly called rose quartz
AI-generated identification · may be incorrectPale pink, translucent to opaque, with a vitreous luster and irregular fracture; hardness 7 Mohs, hexagonal crystal structure, and no cleavage. The blocky shape alone does not establish whether it is a single crystal or massive quartz.

Physical properties
Pale pink, translucent to opaque, with a vitreous luster and irregular fracture; hardness 7 Mohs, hexagonal crystal structure, and no cleavage. The blocky shape alone does not establish whether it is a single crystal or massive quartz.
Formation & geological history
Forms in silica-rich pegmatites and hydrothermal veins; its pink color is associated with trace elements or microscopic inclusions. Quartz occurs in rocks of many ages, so the specimen’s age cannot be determined from the image.
Uses & applications
Used for carvings, beads, cabochons, and decorative stone; also collected as a rough mineral specimen.
Geological facts
Quartz is one of Earth’s most abundant minerals, and rose quartz is usually massive rather than visibly crystal-terminated.
Field identification & locations
Identify by its pink color, glassy sheen, hardness, and lack of cleavage; common sources include Brazil, Madagascar, and South Dakota. A scratch test should be done only with permission, since it can damage the specimen.
