Description

The "polti" quarry area is famous among collectors for the large amount of minerals from the Alpine fissures. Most fissures are characterized by the combination of epidote, prehnite and various zeolites. In general, epidote is covered by prehnite and zeolites, indicating that epidote is one of the main minerals within late fissure mineralization. This specimen corroborates what was said previously, we see crystallizations of adularia, prehnite and epidote of great beauty. Delivered in a methacrylate box.
