Likely pink calcite or rose quartz

Calcite (CaCO₃) or quartz (SiO₂)

AI-generated identification · may be incorrect

Small, rough pink-orange translucent specimen with vitreous to pearly luster; calcite has Mohs hardness 3 and rhombohedral cleavage, while quartz has hardness 7 and conchoidal fracture. The blurred image prevents reliable distinction.

Physical properties

Formation & geological history

Pink calcite forms in hydrothermal veins and sedimentary cavities; rose quartz crystallizes in granitic pegmatites. Both are common Phanerozoic minerals with no age determinable from the photograph.

Uses & applications

Used mainly as a collector specimen or ornamental stone; quartz is also important in glass, electronics, and jewelry, while calcite is used in cement, lime, and aggregate.

Geological facts

Calcite effervesces readily in cold dilute hydrochloric acid; quartz does not. A steel nail scratches calcite but not quartz.

Field identification & locations

Common localities include Mexico, Peru, Brazil, and the United States. Test carefully with hardness and acid tests; avoid damaging valuable specimens.
