OLDEURO-106 - Pyrostilpnite - $ 2500 SOLD St Andreasberg, Harz Mts, Lower Saxony, Germany cabinet, 10.2 x 9.1 x 5.3 cm
This specimen is a big (protective) mass of rock holding a protected pocket with an OUTSTANDING crystal of the very rare silver species pyrostilpnite. I have seen many of these, probably more than most, in the US-based collections of Bill Pinch, Josef Vajdak, Kay Robinson, and Mark Feinglos, as well as a few on exhibit in Germany. But for sheer visual pizzazz, this one with its robust upright, freestanding crystal, is really one that appeals to me more than most micro-type species do. The crystal is approx 5.5 x 2 mm in size. Note the label dated 1875, from the Sack collection. From MINDAT: originally described as Feuerblende (Feuer = fire, Blende from blenden = to blind, for the adamantine luster), later translated into Pyrostilpnite (from Greek pyr = fire, stilpnos = bright or shining) All Content and Design ©1996-2010 The ArkenstonePowered by http://mineralwebsites.comBy-species Galleries |
