Description

Here is a rich, very good fiemmeite specimen from a handful that have been made available to collectors. Fiemmeite occurs as nice, long, bladed blue crystals with green malachite on fossil coal matrix.

The San Lugano Permian sandstone site hosts a unique occurrence of copper minerals in coalified logs and all the three known copper oxalates. Fiemmeite (IMA 2017-115), named after nearby Val di Fiemme, is exclusive to this locality and, after extensive searching,  has been confirmed as an extremely rare phase.

Of course author's material from the original study, confirmed by micro-Raman spectroscopy at the Science Museum of Trento.
