Item Description
A really cute combination from Panasqueira. About six, classically layered, tan siderite crystals are aesthetically set on quartz crystal matrix. The secondary coating on both species is dramatically accented by sparkly isolated and clusters of brassy pyrite cubes and elongated, striated arsenopyrite or marcasite prisms. The recent excellent article in the Mineralogical Record highlights this famous locale. Choice, unusual and excellent combination material. Ex Bob Trimingham Collection and acquired in 1984.
