A very aesthetic sphalerite specimen from the Elmwood Mine. A large, 6.5 cm wide, corsage-like ball of splendent, ruby-jack sphalerite crystals is beautifully perched on a sliver of silicified limestone covered with pearlescent dolomite rhombs. The tiny purple fluorites scattered about the dolomite are a fine accent. Ex. Mullane Collection and accompanied by a 1970s-era Roberts Minerals label.
