The specimen is fluorite from the Rogerly Mine in England. These are truly stunning fluorites from this location and are among the best in the world for their species.
The first image was taken under a long wave light. There is a strong blue fluorescence to the specimen.
The second image below was taken under short wave ultraviolet light. It has a more electric shade of blue than the first image. An interesting note to this mineral is that, due to its exposure to short wave ultraviolet light, it will phosphoresce for a good while after the lights are turned off. I have timed phosphorescence of specimens of this material in my own cabinet for over half an hour. Once your eyes adjust to the darkness this material will have a glow which will grow fainter gradually.
