A friend brought over his digital camera setup this past Saturday and he took pictures of fluorescent minerals from my collection. This was his first effort at photographing fluorescent minerals, and my first time photographing these rocks with something besides a cellphone camera. I couldn't be happier with the results.
Cubic, twinned fluorite crystal from the Rogerley Mine, Weardale, County Durham, England, shown under longwave UV. Distinct zoning is visible in the upper face of the top twin as a series of faint, nested rectangles. Length of the upper crystal is 15mm (0.6"), FOV approximately 30mm wide.
Platy crystals of fluorescent yellow-green phlogopite on lazurite crystals, non-fluorescent dark blue, both over fluorescent red calcite crystals. A small patch of fluorescent orange hauyne is also visible along the top. Shown under midwave and longwave UV. This specimen is from Kokcha Valley, Sar-e-Sang, Badakshan, Afghanistan. The largest phlogopite crystals are 3mm, FOV approximately 20mm.
Large, terminated gypsum crystal from Red River Floodway, Winnipeg, Canada, shown under shortwave UV. Crystal is 25mm across and 20mm long from the base. FOV approximately 30mm.

Cerrusite crystals from Mibladen, Khenifra Province, Morocco, shown under midwave UV. Large crystal as shown is 15mm across, FOV approximately 25mm.
