Honey calcite (likely calcite-rich marble or vein fragment)

Calcite, calcium carbonate (CaCO₃)

AI-generated identification · may be incorrect

Translucent honey-yellow to cream with white and brown inclusions; vitreous to pearly luster and irregular-to-rhombohedral cleavage. Mohs hardness 3, typically white streak, and strong effervescence in dilute hydrochloric acid; crystals are trigonal.

Physical properties

Formation & geological history

Calcite precipitates from groundwater, hydrothermal veins, limestone, and marble-forming systems. The specimen’s exact age and setting cannot be determined from the photograph.

Uses & applications

Used for cement, lime, aggregate, and construction stone; attractive honey calcite is collected and occasionally cut for decorative objects or cabochons. It is too soft for durable everyday jewelry.

Geological facts

Calcite commonly shows birefringence, producing a doubled image through clear pieces. Brown areas may be iron oxides, clay, or associated quartz/dolomite rather than part of the calcite itself.

Field identification & locations

Identify by low hardness, rhombohedral cleavage, and vigorous acid fizz; quartz or chalcedony inclusions may resist scratching and acid. Common worldwide in limestones, marbles, caves, and mineral veins.
