A very choice cluster of Fluorite in zoned cubes on a Quartz matrix that has a few small Calcite crystals as well. One of the older Fluorite localities of the famed Southern Illinois region, the Deardorff Mine was both prolific and had distinctive habits. This specimen is vintage 1950 era and has small bits of adhering Petroleum on the back as was typical there. This piece has all the 4 main crystals in undamaged condition and two cubes also show excellent isolation. Quartz crystals were not very typical as matrix in the other mines of this zone, but the Deardorff was an exception.
