Beautiful pair of Calcite Crystal Cluster & Onyx Egg-Shaped on custom stands A calcite refers to a naturally formed or artificially shaped crystal of calcite that exhibits a cubic form. Calcite typically crystallizes in the trigonal crystal system, forming rhombohedral or scalenohedral crystals. However, under certain conditions, calcite can form cubic crystals. These cubic crystals are relatively rare compared to other forms of calcite. Calcites are characterized by their geometric shape, resembling with six square faces. The edges and corners are often well-defined, creating a symmetrical and aesthetically pleasing crystal. The formation of calcite can be influenced by factors such as temperature, pressure, and chemical composition of the surrounding environment. Calcite crystals are typically found in areas where there is enough space for crystal growth without interference from other minerals. Calcites are fascinating examples of the diversity of crystal forms that minerals can take, showcasing the natural beauty and symmetry inherent in crystalline structures. Onyx is a type of gemstone that belongs to the cryptocrystalline form of quartz. It typically forms in the cavities of igneous rocks, especially volcanic lava flows, where silica-rich fluids deposit layers of quartz over time. This process creates the characteristic banded appearance that onyx is known for, with alternating bands of different colors. While black and white banded onyx is the most common, it can also occur in shades of brown, red, green, or other colors. Onyx is characterized by its fine texture and glossy, polished surface. It has a smooth feel and often exhibits a high level of translucency when properly cut and polished. The bands in onyx can vary in thickness and arrangement, ranging from straight and uniform to irregular and wavy, depending on the specific conditions of formation.
