Pink quartz crystal (probable rose quartz)

Quartz, silicon dioxide (SiO₂); likely rose quartz

AI-generated identification · may be incorrect

Mohs hardness 7; pale pink to rose color, vitreous luster, translucent appearance, and hexagonal/trigonal crystal structure. Quartz has no true cleavage and shows conchoidal fracture; the image is too small for precise identification.

Physical properties

Formation & geological history

Rose quartz forms mainly in granitic pegmatites and hydrothermal veins, with color commonly caused by microscopic inclusions. Such specimens formed during ancient Precambrian-to-younger magmatic and hydrothermal events.

Uses & applications

Used as a lapidary and ornamental stone, in carvings and jewelry, and commonly sold as a collectible mineral. Ordinary small pieces have modest commercial value.

Geological facts

Quartz is one of Earth’s most abundant minerals and is piezoelectric. Rose quartz commonly occurs massive rather than as sharply formed crystals, so this may instead be pink calcite or another pink mineral.

Field identification & locations

Common sources include Brazil, Madagascar, India, and the United States. Confirm with hardness and streak tests: quartz scratches glass and leaves a white streak; acid testing helps distinguish calcite.
