The speciment was found in the classic location in the mountains of Bumansfjord, Seiland, Finnmark, Norway. The stone is 460 grams, and measures 56 x 118 x 62 mm.
It is a nice diopside, but it got some crushes at the bottom. It has also a nice cluster of 3 Grossular crystals that has grown together.
Most of the year the field where the minerals are found is covered with ice and snow. This area is now a part of the Seiland National Park, and collecting from this area is now strictly forbidden.
This specimen was found in the late 1980s by my father, Gunnar Mathisen.
