Fluorite with Orthoclase (strongly fluorescent!) (ex Willard Wulff Collection)

Item Description

The area around Pikes Peak in Colorado is full of pegmatites with with Quartz, Feldspar and Fluorite. This piece comes to us from the collection of Willard Wulff, who was a Colorado native, a field collector, and one of the founding members of the Colorado Springs Mineralogical Society in 1936. You can read Willard's bio on the Mineralogical Record website here ( http://www.minrec.org/labels.asp?colid=1528 ). This piece is the only specimen I've seen from this specific locality and comes with a typed label from Wulff with the locality information. I had to do a bit of digging to find out specifically where Artist's Glen is, but it's a legit locality, west of Manitou Springs, very near the Pikes Peak cog railway line. The piece features a predominant, sharp, translucent, pastel greenish color cube of Fluorite measuring 2.1 cm sitting with smaller associated Fluorite and cream colored Orthoclose. It's a fairly decent quality specimen, and a cool esoteric piece for any Colorado collector, but the most important aspect of the piece is the impressive fluorescence! Under short wave UV light, the Fluorite glows a bright sky blue, and the Orthoclase has a brilliant rich pink fluorescence, and under long wave UV light, the Fluorite shifts to a strong purple, and the Orthoclase has a light peachy fluorescence. A cool old time piece from this historic and well-documented collection.
