Peach/orange calcite cluster

Calcite (CaCO₃), likely botryoidal or scalenohedral aggregate

AI-generated identification · may be incorrect

Pale orange to peach, translucent crystal cluster with vitreous to pearly luster. Mohs hardness 3; perfect rhombohedral cleavage, trigonal crystal system, and specific gravity about 2.71. Effervesces strongly with dilute hydrochloric acid.

Physical properties

Formation & geological history

Calcite precipitates from carbonate-rich groundwater, hydrothermal veins, caves, and sedimentary cavities; orange color may reflect iron or other trace impurities. The specimen’s exact age cannot be determined visually.

Uses & applications

Used in cement, lime, construction aggregate, soil treatment, and chemical industries; attractive clusters are sold as inexpensive collector specimens and décor.

Geological facts

Calcite is one of Earth’s most abundant minerals and commonly shows strong double refraction. Orange calcite is often marketed as “honey calcite,” though that trade name is not a distinct species.

Field identification & locations

The image is consistent with calcite, but aragonite or orange fluorite are possible without tests. Test softness against a copper coin or steel knife, cleavage, and acid reaction; Rochester-area finds are plausibly carbonate minerals from local sedimentary glacial materials, though this may be a purchased specimen.
