Rich amber yellow, glassy fluorite with chalcopyrite inclusions and associated calcite. Center of one crystal shows internal etching near the center with coincidental purple color. Nicely balanced specimen in excellent condition. Mined ca. 1960s-1970s. Wayne Fowler Collection. Entered into Ross C. Lillie database as RCL2605. (Note: the Bethel Level was highly productive in this time period and produced material like this from Ozark-Mahoning properties hoisting from the M.F. Oxford #7, Heavy Media Shaft #4, consequently so a mine attribution is not possible).
