Polished pink quartz pebble, likely rose quartz

Quartz, silicon dioxide (SiO₂), with trace iron, titanium, or manganese

AI-generated identification · may be incorrect

Pale pink, smoothly tumbled, and translucent to opaque with a vitreous luster; hardness 7 Mohs, hexagonal crystal structure, no cleavage, and conchoidal fracture. The small size and surface reflections limit certainty; it could also be pink feldspar or a dyed stone.

Physical properties

Formation & geological history

Rose quartz forms mainly in granitic pegmatites and hydrothermal veins, crystallizing from silica-rich fluids during igneous activity. Most specimens are Precambrian to younger, with major deposits in Brazil, Madagascar, India, and the United States.

Uses & applications

Used as an inexpensive ornamental stone, carving material, beads, cabochons, and metaphysical collectibles; it has little industrial value compared with ordinary quartz.

Geological facts

The pink color is commonly attributed to microscopic inclusions or color centers rather than visible impurities. True rose quartz often lacks well-formed crystals and is commonly sold polished or tumbled.

Field identification & locations

Test hardness against glass and inspect for conchoidal fracture; quartz should scratch ordinary glass, while feldspar generally should not. Common loose tumbled pieces are widely sold in mineral shops and gift stores.
