MUSEUM SIZED CALCITE from spain - Height: 16 cm - Width: 13.1 cm- 1231 g - (1)

Calcite is one of the most common and widespread minerals on Earth, composed primarily of calcium carbonate. It forms a variety of crystal shapes, including scalenohedra, rhombohedra, and prismatic crystals, and exhibits a range of colors from white and clear to shades of yellow, green, and blue. A museum-sized calcite specimen from Spain showcases the impressive size and crystallographic beauty that calcite can exhibit. The mineral is notable for its perfect cleavage and characteristic optical property called double refraction, where objects seen through the crystal appear doubled. Calcite is extensively studied in geology and crystallography and is also prized by collectors for its clarity and crystal formations. Large specimens like this one also serve educational purposes and decorative roles in various settings.
