Adularia (East Tyrol, Austria)
Pragraten, East Tyrol, Austria. 90mm x 70mm x 20mm.
From a really unusual locality. The tiny label on the back of the specimen is as follows "Adulaar, Umbalthal, Pragraten" With a little bit of research we where able to note that this is a unique locality, the specimen dates back quite a while and originates from a very old collection we acquired some years back.
