Rock Crystal (Historical) - St. Gotthard, Switzerland
 Ex  Robert Scheck Collection, Ex Museum Vienna
 
 Historical rock crystal specimen of the best quality from the St. Gotthard massif. The piece was traded by the Vienna Museum in 1984. The piece is immaculate and recrystallized all around. A well-defined sharp-edged crystal faces a nicely healed crystal with numerous faces. At the base, all surfaces are recrystallized and partly double terminated.
