Description

Unfortunately the photos don´t do justice to the specimen - the rock crystal is in fantastic quality - it is water-clear, the luster is superb and the faces show a truly amazing texture. It is framed with brown-grey calcite crystals to the left hand side and also the back is covered with calcite and minor matrix. Material from Wolfskogel mountain is very rare and hard to obtain - so this piece shoudl be high ranked for quality and rarity! Much better in person.
