This is a glittering, U-shaped cluster of purple Fluorites dramatically coated by Ruby Jack Sphalerites. The majority of the Fluorite cubes are covered by sharp Sphalerites with a luster that ranges from good to excellent. It is not unusual to see this combination, but the rich coating of Sphalerites IS somewhat unusual. Mined in 1984. The largest Sphalerites range up to about 9 mm. Nice aesthetics for "just" a sphalerite! RCL1964
