2.05" Calcite After Calcite with Pyrite - Kjørholt Mine, Norway
This is a 2.05" long, scalenohedral calcite crystal that is partially engulfed within a hexagonal calcite crystal. Small pyrite crystals formed over the scalenohedral calcite, resulting in a gorgeous phantom that's visible through the clear hexagonal calcite. When shining a light at this specimen, the pyrite exhibits a brilliant sparkle. This specimen was collected from the Kjørholt mine near Porsgrunn, Norway.
This specimen has been mounted to an acrylic display base with mineral tack.

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.
