Killer group of five (5) wulfenites from the now closed Red Cloud mine in La Paz Co., Arizona. The group includes three (3) single crystals, one V-twinned crystal group, and a small cluster of 5 or so crystals. All of these were once in the Arthur Montgomery collection and were likely collected by Art with his collecting buddy Ed Over, during his many forays into the Arizona outback in the 1930s. THIS MATERIAL IS EASILY DISTINGUISHABLE from more modern, less hefty crystals. Hauck purchased them from Montgomery! I couldn't bear to break up such a neat set to sell them separately. What a treasure! The crystals are all of the best quality with outstanding luster and bright orange-red color. 2.4 x 1.3 x 0.6, 1.9 x 1.8 x 0.5, 2.5 x 2.3 x 1.1, 1.7 x 1.9 x 0.4, 2.0 x 1.9 x 0.6 cm
