Siderite & Pyrite on Quartz (Soregaroli Coll.)

Item Description

A fantastic, highly deceptive and aesthetic two-sided combination rib from the famed Panasqueira Mine and the Art Soregaroli Collection. Isolated sharp siderite disks are dramatically and preferentially coated with scintillating tiny pyrite crystals on the front. BUT, the siderite and pyrite lie on the side of pristine, sharply terminated, water-clear to translucent, flattened quartz crystal! Certainly an outstanding and unusual classic combination from this noted locale.
