Calcite Crystal cluster - Height: 20 cm - Width: 15 cm- 1.5 kg

Calcite is one of the most abundant and widely distributed minerals on Earth, known for its varied crystal shapes and vibrant colors. The calcite crystal cluster described here features an array of intergrown crystals, typically exhibiting a rhombohedral or scalenohedral form. These clusters form through precipitation from calcium carbonate-rich waters, often in sedimentary or metamorphic environments. The translucent to transparent crystals can display a spectrum from colorless to white and beyond, depending on impurities. Collectors prize calcite for its optical properties, including birefringence, which can cause double images when objects are viewed through the crystal. Such clusters are also popular in decorative displays and educational collections due to their striking geometric forms and relative fragility compared to other minerals.
