I vividly remember the times when I was a teenager, in the beginning of the 1980s. Fluorites from the Artenberg Quarry of Steinach were the most desired ones of Black Forest, due to the fact, that the heyday was already over and the miners worked in another part of the quarry. And here we have a fine combo of sharp and green octahedral Fluorite and creamy glistening Calcite. The Fluorite is sharp edged and well terminated. It has no imperfection but a contact at the side. In any case a great thumber, hard to obtain nowadays.
