While we often offer Fluorite that has a fluorescent response, only rarely have we heard of one with a distinct phosphorescence. When the stone is subjected to a shortwave UV source, and then that source is removed, the gem will glow with a chalky blue-white phosphoresence for around 5 seconds before that fades away. Our best attempt at catching this color is in the right-hand photo above. Really fascinating, from a newer source in Paksitan. The standard daylight color, a soft green, is quite lovely as well.
