Tan-coloured bladed (shallow-angled rhombic) crystals of Siderite, to 1.3 cm across, are accompanied by small, glassy, terminated Quartz crystals in tight radiating sprays on a matrix of massive Siderite. This attractive miniature specimen comes from the famous historical Příbram District in the Central Bohemian Region, Czechia and under magnification has extra detail. This includes tiny white to pinkish rhombs of Calcite and tiny 'balls' of brassy Pyrite both sitting along the sharp tips/edges of the Siderite crystals. Ex Hans Engelbrecht Collection, no. 1594, Engelbrecht acquired it on an unrecorded date from Frantisek Frk.
