Rose quartz (likely)

Quartz, silicon dioxide (SiO₂), pink variety

AI-generated identification · may be incorrect

Pale pink, translucent to opaque, with a vitreous-to-waxy luster and uneven fracture; quartz has Mohs hardness 7, no cleavage, trigonal crystal structure, and specific gravity about 2.65. The rough, granular appearance may also indicate pink quartz-bearing granite or pegmatite rather than pure quartz.

Physical properties

Pale pink, translucent to opaque, with a vitreous-to-waxy luster and uneven fracture; quartz has Mohs hardness 7, no cleavage, trigonal crystal structure, and specific gravity about 2.65. The rough, granular appearance may also indicate pink quartz-bearing granite or pegmatite rather than pure quartz.

Formation & geological history

Forms mainly in silica-rich igneous pegmatites and hydrothermal veins, with its pink color commonly linked to microscopic inclusions or trace elements. Such specimens may range from Precambrian to younger geological ages.

Uses & applications

Used as an ornamental stone, carving material, tumbled stone, and inexpensive gemstone; massive rose quartz is also used decoratively in countertops and figurines.

Geological facts

Rose quartz commonly lacks well-formed crystals; transparent pink quartz crystals are rarer and may be called crystalline rose quartz. Color can fade with prolonged sunlight or heating.

Field identification & locations

Commonly found in Brazil, Madagascar, India, South Africa, and the United States. Identify it by hardness, pale pink color, lack of cleavage, and glassy fracture; a scratch test should be avoided on valuable specimens.
