Incredibly rare, relatively large cumengeite crystal with 5 of the 6 possible point swell developed (and mounted on a thin pedestal from the rear position). is from the 1970s finds here, after Bill Larson and Ed Swoboda rediscovered the 1890's-era locality. Before that time, the only cumengeite specimens were in a few museums. very HARD TO OBTAIN TODAY in any quality, of course! Formerly in the collection of and with label of Willard Perkins, the collector who invented the so-called "Perky Box" for thumbnails.
