Physical properties

Formation & geological history

Calcite commonly forms when calcium-rich groundwater precipitates in veins, cavities, limestone, and hydrothermal environments. This appears tumbled and polished; its exact geological age and locality cannot be determined from the image.

Uses & applications

Used for cement, lime, aggregate, optical calcite, and ornamental stone; honey calcite is also sold as a lapidary and metaphysical specimen.

Geological facts

Calcite effervesces strongly in dilute hydrochloric acid and may fizz weakly in household vinegar when powdered. Its perfect cleavage makes it easy to scratch and chip.

Field identification & locations

Identify by its low hardness, rhombohedral cleavage, and acid reaction; common worldwide, especially in limestone regions and hydrothermal veins. The specimen is likely a small commercial tumble stone.
