Calcite Crystal on matrix - Height: 12 cm - Width: 8 cm- 425 g - (1)

Calcite crystals are composed of calcium carbonate and are among the most widely distributed minerals on Earth. The specimen described, standing 12 cm tall and weighing 425 grams, likely exhibits the rhombohedral cleavage typical of calcite, which can form interesting translucent and sometimes colorful crystal shapes on a matrix of host rock. Calcite is notable for its optical properties, including double refraction and fluorescence in some varieties. Found in sedimentary, metamorphic, and igneous rocks, it plays vital roles in geological processes. Collectors value calcite for its wide variety of crystal forms, colors, and its presence alongside other mineral specimens in matrices, making it a fascinating piece for study or display.
