4.1" Fluorescent Calcite Geode In Sandstone - Morocco
This is a sparkling half of a calcite crystal filled geode that's partially encapsulated in the matrix it was found in, collected from Aouli, Morocco. The calcite crystals are all beautifully formed and have a faint yellow coloration. Under UV light, the crystals fluoresce the typical orange color seen by other calcite specimens. The geode within the sandstone is 4.1" wide.
The entire specimen weighs just under 10 lbs.

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.
