7.1" Fluorescent Hexagonal Calcite Crystals - China
This is a gorgeous 7.1 x 6.2" cluster of disk-shaped calcite crystals, collected from Daye County, China. The largest faces of the crystals are milky white, with clear/transparent edges that allow you to look right into the crystals. Under shortwave ultraviolet light, the calcite crystals fluoresces a red-orange color.
The edges and base of the specimen have been cut flat, however it's accompanied with a display stand to assist with preferred presentation.

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.
