Here is a huge museum specimen with many huge hexagonal Biotite crystals from Seiland, Alta, Finnmark, Norway.
The specimen measures 117 x 330 x 250 mm and the weight is 12,2 kilograms.
This is a museus size piece for people with special interest.
There are six huge Biotite crystals on the front side, and one at the backside.
I don't know the exact location on Seiland where it was found, but I know that my father found some crystals like this a few hundre meters from the zircon field (closer to the sea).
