Sphalerite (rare locality specimen) Limonite A great quality specimen forOne of the VERY FEW Sphalerite specimens that I have seen from the Chicote Grande mine in Bolivia. This mine is best known for its astoundingly fine Japan Law twinned Quartz specimens, which sometimes played host to beautiful jet black Ferberite crystals!
