In Search of that Elusive Red Response in Fluorite to Upper Band Long Wave UV

Don Newsome, an avid collector of fluorescent minerals and president of UV Systems, a manufacturer of high quality UV lamps and accessories, pauses to examine a specimen of Spanish Fluorite. “Very rarely, perhaps with just five specimens out of hundreds I have examined, will one see red response to the upper band long wave . . . This [very rare] response seems insensitive to the color of the crystals” The specimen in question did not have that trait, and Don moved on—the search continuing.
