Documented specimens from Alcoa are rare. Not only is this is an excellent specimen showing classic morphology and luster, but the color is unusually rich and appealing. Nice associated calcite and micro-chalcopyrite add interest and aesthetics. Collected by Bud "Doc" Hicks who trimmed excess matrix with lapidary saw to reveal the color. Specimen is in excellent condition excepting a few small cleaves. Rare.
