The specimen was found in the classic location in the mountains of Bumansfjord, Seiland, Finnmark, Norway. The specimen got a weight of 522 grams, and measures 50 x 122 x 93 mm (height x length x width)
The whole stone is a massive piece of green transculent diopside, with a small layer of cola-brown grossular crystals.
You will see some damages, but overall it is good quality and nice looking. Please watch the video for a better look. The last pictures is from is underside.
This area where it was found (Bumannsfjorden) 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.
