Rock crystal skeletal quartz – Teufelsmühle, Habachtal, Salzburg, Austria
 Rock crystal is skeletonized all around. Its clarity, like melting ice, and its outstanding luster across all surfaces characterize this piece from the Habach Valley.
 Rauris is known for its diverse rock crystal deposits. Almost all of the deposits are located in the core zone of the Hohe Tauern National Park. For several years now, collecting minerals here has only been permitted with a special permit. As a result, minerals from Rauris are rarely offered for sale. The rock crystal comes from the collection of Josef Kolb, who regularly searched for minerals there since the 1970s.
