Sharp, vivid purple fluorite cubes with outstanding gemminess and luster form a superb, 3-dimensional cabinet plate from the famous, but less well-known Deardorff Mine of the Illinois Fluorspar District. The two largest cubes are 3.8 and 3.6 cm wide. The fluorites are beautifully accented by scattered quartz crystal clusters and there are even a few ruby-jack sphalerite crystals. This is classic, old-time material from this mine dating from the 1930s to 1950s, as the mine closed in the early 1960s.
