UV Reactive Columnar Calcite Cluster Specimen Birthstone Featuring many "flower" crystal growthsThis 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.
