A group of naturally etched Calcite crystals with glassy lustrous faces and built from stacks of much smaller sub-mm crystals. From the Abendröthe mine near to St. Andreasberg in Lower Saxony, Germany, the specimen is a jumble of colourless, milky-white and light grey scalenohedral Calcite crystals to 4 cm.
Ex. the Mineral Collection of Archduke Stephan Franz Viktor of Hungary (1817 to 1867), with a historic Archduke (Erzherzog) Stephan label incorporating his coat of arms. This label measures 7.4 x 7.3 cm and has been trimmed, so losing some of the printed and hand-written text. It is understood these labels were trimmed by curators at the Museum of Natural History of the Humboldt University in Berlin, to fit within their specimen boxes, after being bequeathed by Carl Rumpff’s widow in late 1889. A Carl Rumpff label, dated 1889, is attached to the specimen.
