My Rogerley Mine green fluorite showing off its insane neon-blue fluorescence! Rogerley Mine specimens are SO fluorescent, they can fluoresce in daylight, but I took this picture in a dark room to try and capture this piece at its best. Still could’t quite get it. This thing is much brighter in person!
Fluorite, Rogerley Mine,
Weardale district, County Durham, England. Pic 1 shows the specimen exhibiting daylight fluorescence under sunlight, pics 2 & 3 show the same specimen under white light and short wave ultraviolet.
