Wulfenite (Ref: 145)

A fine specimen with hundreds intense yolk yellow, multifaced and excellent developed crystals of Wulfenite scattered over typically carbonatic matrix. The crystals are sharp edged, highly lustrous and mostly perfect. Just at the periphery there are some imperfections, but I´m pretty sure, that a good lab is able to remove them easily. This is an unusual and colourful specimen in splendend condition from the typelocality; Bleiberg in Carinthia. Renamed in 1845 by Wilhelm Karl von Haidinger in honor of Franz Xavier von Wulfen [November 5, 1728, Belgrade, Serbia - March 16, 1805, Klagenfurt, Austria], botanist, mineralogist, alpinist and a member of the Order of the Society of Jesus (Jesuit). Wulfen authored a monograph on the lead ores of Bleiberg, Austria. This mineral was originally named ´plumbum spatosum flavo-rubrum, ex Annaberg, Austria´ in 1772 by Ignaz von Born. In 1781, Joseph Franz Edler von Jacquin called the mineral ´Kärntherischer bleispath´. Other names were later proposed. (mindat)
