Physical properties

Formation & geological history

Quartz crystallizes from silica-rich igneous and hydrothermal fluids, commonly in pegmatites and veins; rose quartz deposits are generally Precambrian to younger. The specimen was later cut or tumbled by humans.

Uses & applications

Used as an ornamental and lapidary stone, in beads, carvings, décor, and inexpensive jewelry. It has modest collector value unless strongly colored, translucent, or unusually included.

Geological facts

Rose quartz is usually massive rather than well-crystallized; transparent pink quartz crystals are uncommon and are often called pink quartz. Quartz has a distinctive glassy appearance and is harder than ordinary steel.

Field identification & locations

Common sources include Brazil, Madagascar, India, South Africa, and the United States. Confirm with a scratch test only on an inconspicuous area: quartz should scratch ordinary glass, though coatings or look-alike glass can confuse identification.
