Druzy UV Reactive Columnar Calcite Cluster Specimen Fossil which are actually tiny crystalsThis striking calcite specimen is a true beauty! Under normal light conditions, it appears as solid gray columns of calcite. But when exposed to ultraviolet (UV) light, it transforms into a fiery orange hue. This phenomenon is caused by calcite's property of fluorescence, which refers to its ability to absorb UV light and then emit visible light of a different color. Approximate Size: L: 1. 10" x W: 3. 20" x H: 1. 70" Approximate Weight: 0. 10 lbs.
