A Quartz plate attached to a vuggy mound of Quartz veinstone is richly coated with deep blue-green Pseudomalachite as aesthetic stalagmitic rods to typically 5 mm. The richest part of the specimen is a roughly 3.5 x 3.5 cm area completely masked by such rich druses. A superb Pseudomalachite from Ľubietová (Libethen) in Slovakia.
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 7.0 x 4.7 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. The label is numbered 135/14 and a small label bearing this same number is glued beneath the specimen together with a Carl Rumpff label, dated 1889.
