Calcite from Malmberget, Norrbotten, Sweden
Size: 77x170x112 mm (1352 gr.)
A great dog tooth calcite that is undamaged except on the edges. The crystals are white translucent, a little yellow at the bottom. If you look closely at the top you will see that several of the crystals are grown in two layers. In the middle a thin crystal that is pointing out on the top of several of the crystals (best seen the second picture).

I am not sure what year it was collected, but assume about 20 years ago. My father were buying/swapping the Swedish material directly with the miners/mineral friends in Northern Sweden.
