Description

You are bidding on a truly exceptional sample two very large groups of perloffite crystals in two different vugs. The clusters are composed of numerous prisms and there are also several single crystals in many of the crevices. In the main vug there is also a large group of crystallized native copper and several small cuprite crystals amongst numerous small plates of apatite. This is an exceptional sample I obtained from Museum Victoria many years ago. Very photogenic and very rich for this species.
