Description

In my evaluation this specimen is wrong labeled as Columbite, it is most likely Thorite. Columbite from Sweden never came in this size. Thorite fit´s for habit as well for locality. The crystal is very large for the mineral, well developed all around and for Thorite in excellent quality.
