Dogtooth Calcite
Dogtooth spar is a speleothem that consists of very large calcite crystals resembling dogs' teeth. They form through mineral precipitation of water-borne calcite. Dogtooth spar crystals are found in caves, open spaces including veins and fractures, and geodes.


Malmberget:
​It is 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.
