Pyrites are uncommon from Panasqueira, and this impressive specimen is actually amazing for the locality. The surface display shows off two generations of Pyrite, with the second larger generation having intergrown crystals to 2 cm on edge and covering a rolling carpet of smaller crystals. The pyrites rest on an Aresenopyrite matrix, and there is an Apatite added on top as a bonus. Good Pyrites from Panasqueira should be as treasured as any other species from this important locality, and this one will add to the breadth of any Panasqueira collection. Much better, even, in person, because the luster and sheer metallic flash of the piece is hard to capture.
