Tumbled pink quartz (probable rose quartz)

Quartz, silicon dioxide (SiO₂), likely rose quartz

AI-generated identification · may be incorrect

Hardness 7 Mohs; translucent pale pink to brownish pink, with a vitreous-to-waxy luster and no visible cleavage. Quartz is trigonal and commonly shows conchoidal fracture; the rounded shape indicates tumbling or natural abrasion.

Physical properties

Formation & geological history

Rose quartz forms mainly in granite-related pegmatites and hydrothermal veins, crystallizing from silica-rich fluids, generally during Precambrian to Phanerozoic geological events. The specimen may also be ordinary quartz colored by microscopic inclusions or irradiation effects.

Uses & applications

Used as an ornamental stone, beads, carvings, cabochons, and inexpensive jewelry; quartz is also important industrially in glass, ceramics, electronics, and abrasives.

Geological facts

True rose quartz is usually massive rather than well-crystallized, while pink crystalline quartz is relatively uncommon. Color can fade with prolonged sunlight or heating.

Field identification & locations

Common sources include Brazil, Madagascar, India, South Africa, and the United States. A glass-scratching hardness test, lack of cleavage, and waxy pink appearance support quartz identification, though laboratory testing is needed for certainty.
