Physical properties
Pale honey-yellow, translucent mineral with vitreous to pearly luster and irregular cleavage surfaces; Mohs hardness 3, typically rhombohedral crystal structure, specific gravity about 2.71. The image is insufficient for definitive identification; yellow aragonite or quartz are alternatives.
Formation & geological history
Likely formed in carbonate veins, caves, or sedimentary limestone environments through hydrothermal or groundwater precipitation; age varies widely from Paleozoic to Recent. Its rounded shape indicates human tumbling or natural abrasion.
Uses & applications
Used for cement, lime, construction aggregate, optical calcite, and decorative specimens; attractive transparent pieces are collected but generally inexpensive.
Geological facts
Calcite effervesces vigorously with dilute hydrochloric acid or vinegar when powdered, unlike quartz. It commonly shows strong double refraction through clear pieces.
Field identification & locations
Test cautiously: calcite scratches with a copper coin or steel knife and reacts with acid; quartz does not and is much harder. Common worldwide, especially in Mexico, the United States, Iceland, and Europe.
