32,5 cm Museum specimen of Stilbite & Calcite from Malmberget
Malmberget, Gällivare, Norrbotten, Sweden
Size: 121x325x115 mm (4555 gram)
The stone was found in Malmberget, Gällivare, Norrbotten County, Sweden.
I am not sure about the year, but my father bought this one directly from his mineral friends in Malmberget, Sweden, probably in the late 1990s/early 2000s.
It is filled with honey yellow Stilbite crystals, and you will see some white leaves of Calcite.
You will find a few white nicks (damages), but overall it is a beautiful specimen. One of a kind.
Please watch the video for the best view.
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.
