Beautiful 4" Dogtooth Hematite Calcite Crystal Cluster - China
This is a cluster of red-orange scalenohedral calcite crystals collected from the Daye iron mine in China. The rich, red coloration is caused by inclusions of hematite within the calcite. The entire plate is 4x3.1" with the largest crystal measuring 2.7" tall. Aside from a very slight impact mark on one edge of a calcite termination, they all seem to have very little damage. It comes with an acrylic display stand.
About Calcite Crystals
Calcite crystals are a form of calcium carbonate (CaCO₃) known for their diverse shapes, transparency, and vibrant range of colors. They typically form in rhombohedral, scalenohedral, or prismatic shapes, often with well-defined, sharp edges and glossy surfaces. Calcite crystals are often translucent or transparent, sometimes displaying a double refraction effect where objects viewed through the crystal appear doubled. They can appear in various colors—white, clear, yellow, pink, blue, green, and orange—depending on impurities or trace minerals.
A notable characteristic of calcite is its reaction with weak acids like vinegar, which causes it to effervesce, or fizz, as it releases carbon dioxide. This property makes calcite crystals a key tool in geological identification and studies. Calcite forms in many environments, from sedimentary rocks like limestone and marble to hydrothermal veins.
