Wyoming fluorescent minerals
The specimens shown at right are calcite from Wyoming. The specimens are a white to light tan in normal light. The specimens are reflecting the ultraviolet lights in the purple areas of both the long and short wave light photos. The calcite fluoresces a creamy white to yellow under the long wave light. and an electric white under short wave ultraviolet light. The green fluorescence in the far right photo is a light coating of drewsy quartz (chalcedony).
The third row of images are of selenite "hourglass" rhombs from Buffalo, Wyoming. They are the first of this specimen that I have seen anywhere. They will fluoresce under both long and short wave ultraviolet light, but they fluoresce best under both wave lengths at the same time. They have a classic hourglass image within the rhomb under UV lighting. Under normal lighting they look like normal selenite except for their shape.
