A superb cabinet combination plate with very gemmy, golden-yellow sphalerite crystals, brassy chalcopyrite crystals and a few, scattered galena crystals from the small find a few years ago at the Commodore Mine at Creede, Colorado. Many of the highly lustrous, black-looking sphalerite crystals are, in fact, partially gemmy. The largest gemmy sphalerite crystal is 1.3 cm. Ex. Ed David Collection.
