Item Description

A textbook, 3-sided, tetragonal, chalcopyrite crystal thumbnail with mirror-bright, brass-yellow color and complexly intergrown crystal faces. One face has nifty, iridescent, peacock-blue/purple highlights. Complete all-around and very nearly pristine, a very trivial bit of edgewear is barely noticeable and is certainly not a detraction. Classic material from the famous Panasqueira Mine and the Carlton Davis Collection.
