Phosphorescent Puttapa - Willemite Calcite, Australia
The pic directly below was taken with no lights - NONE. It is a piece of very phosphorescent material from the Puttapa mine in Australia. I was quick enough to even capture the brief intense phosphorescence (BIP) from the calcite. The colors are amazing when captured with a camera, but your eye averages everything out to a green glow.
The 2nd pic shows the same piece under shortwave UV.
