Physical properties
Mohs hardness 3; pale honey-yellow to cream, vitreous to pearly luster, and trigonal crystal structure. The prominent flat cleavage surfaces and blocky form are consistent with calcite; specific gravity is about 2.7.
Formation & geological history
Typically forms when calcium-carbonate-rich fluids precipitate in veins, cavities, or sedimentary settings; the yellow color commonly comes from trace impurities. The specimen’s exact age and locality cannot be determined from the image.
Uses & applications
Collected and used as a decorative stone; calcite is also an important source of lime and cement and is used in building materials and industry.
Geological facts
Calcite effervesces in dilute acid and has perfect rhombohedral cleavage, often breaking into angled, glassy-looking faces.
Field identification & locations
Look for softness, strong cleavage, and fizzing with dilute hydrochloric acid; yellow calcite occurs at many deposits worldwide. The image shows a pale-yellow, cleavage-rich specimen, but identification is visual rather than definitive.
