This specimen, while not being a great display piece in white light since some crystals are broken, is still a pretty nice fluorescent specimen. It fluoresces under all three wavelengths, showing subtle color variations between SW & LW; MW is pretty close to LW, therefore not shown.
Both the SW fluorescence and phosphorescence are a cooler color than the LW fluorescence and afterglow.
Size: 5,3 cm X 5 cm X 3 cm
Shown in the gallery below, respectively: Shortwave UV fluorescence, SW phosphorescence, longwave UV fluorescence, LW phosph., Visible light.
