Thumbnail, 2.5 x 1.9 x 1.5 cm
Walpurgis vein, Weisser Hirsch Mine, Schneeberg District, Erzgebirge, Saxony, Germany (TYPE LOCALITY)

This specimen contains crystals of bright yellow walpurgite showing EXTREMELY well-developed, sharp crystal form (distinguishing them from a later find of richer coverage, but smaller XL size). The crystals are quite large for the species AND so much coverage on one specimen is also uncommonly seen. A Walpugis specimen today on the market is EXTREMELY rare and I have seen but a handful (and bought up every one when offered me at any normal price). It is very probable from the style of crystallization, quantity, and size of the crystals (to 1.2 mm) that this specimen is from the type find of the species in the 1870s. Even after, this notable old find was not surpassed in quality, although a few later pockets were found over the years. There are probably other micro-sized species present here, as well.
