Calcite from Kjørholt, Telemark, Norway
Size: 62x66x50 mm (177 gr.)
These are phantom crystals grown in layers, where the inner layer is covered with pyrite. The outer layer is transparent. The last 2 pictures are taken with extra light to expose this.
The specimen has some few nicks and damages on the edges.
I am not quite sure when it was found. But me and my father visited the mines in December 1992, together with a guy that worked in the mines. At this time he also bought some specimens. I cannot guarantee it is from this year, it could also be found some years later.
