14.3" Tabular Nailhead Spar Calcite Crystals on Quartz - China
This is an alluring, 14.3" wide mineral specimen comprised of tabular calcite crystals with nailhead spar terminations, scattered across at matrix encrusted in small quartz crystals and iridescent pyrite. Beautiful translucency on these relatively large calcite crystals. This material comes out of the Leiping Mine in Hunan, China.
Under shortwave UV, the calcite crystals give off an orange fluorescence. It comes with a 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.
