265 mm Calcite from Malmberget
Malmberget, Gällivare, Norrbotten, Sweden
Size: 158x265x122 mm (3688 gram)
Here is an unique chance to get this old beautiful museum-size specimen from Malmberget.
It has dogtooth calcite all over, partly covered with tiny yellow Stilbite. Mostly undamaged, but there is a few small areas where some crystals are missing/cut.
Please also watch this second video of the specimen, for a better view (not the same video as above):
I don't know when this one was found, but I assume about 20 years ago.
Malmberget has one of the largest underground mines for ore in the world and the second-largest in Sweden. The deepest point is 1390 meters below ground. Annual production is over 5 million tonnes of iron ore.
There is a big variety of crystals and minerals found in the mines:
Sometimes the miners hit pockets with crystals, but seldom they are collected as it would slow the work. Luckily there are workers who are trying to save/collect the most interesting stuff.
My father had friends in the mining companies in Sweden and traded minerals directly from them. Most of the stuff he got was back about 15-25 years ago. Much of this material is now long gone, and seldom seen on the market.
