A really nice discoidal siderite crystal with some heft to it and a really pleasant hazelnut-colored surface with excellent luster and definition. This piece comes from the classic Portuguese deposit of Panasqueira, a mine developed to exploit a series of tabular veins of Sn–W mineralization that have produced some of the finest sulfide and fluorapatite specimens in the world and definitely from Europe.
