The Wein Collection, which was dispersed about 4 years ago, contained all sorts of rare and unusual Swiss and Alpine specimens. Here is another - a large, egg-shaped geode full of prehnite and calcite. The prehnite is in colorless to very faintly green balls, and the calcite, in little rhombs. Unuusal locality piece!
