Rocks and stones (no mining) in a small area near the Ramberg pluton in the forest about 1 km west of Friedrichsbrunn village.

The occurrence of the vesuvianite rocks at the Bocksberg near Friedrichsbrunn was discovered by K.A. LOSSEN (a famous Harz-geologist) in the 2nd half of the 19th century. Since then the locality was visited by many geologists (DAHLGRÜN is the most known of them), but came in oblivion in the last decades.
Although in later years vesuvianite was found at different other locations in the Harz mountains (e.g. Radau valley near Bad Harzburg and Hagental valley near Gernrode), sporadic and in minor quantity, the Bocksberg is still the most important locality in the Harz mountains for vesuvianite.
At the Bocksberg, the (massive) vesuvianite is the main component of the rocks, some are nearly exclusively formed from vesuvianite. However, good crystals in this compact rock are rare. The best crystals can be found in a cavernous garnet rock, but it is not easy to find this kind of rock.
