Calcite Crystal Cluster – USA

This calcite crystal cluster from the USA measures 11 × 10.5 cm and weighs 1 kg. Sharp, well-formed calcite crystals in warm honey tones show translucent clarity, their coloring coming from trace iron within the crystal structure. As one of the most common carbonate minerals, calcite occurs worldwide in an enormous range of colors and crystal habits, and this compact, geometrically sharp cluster with strong natural luster is a good example of its more collectible forms.
