Smoky Quartz with Fluorite – Rufibach Kluft, Zinggenstock, Bernese Oberland, Switzerland
 
 One of the legendary finds in Switzerland is the cleft discovered by Ernst and Hans (+ 1971) Rufibach on the Zinggenstock in the early 1960s. Characteristic of this find is the paragenesis of flawless smoky quartz and pink fluorite with a packeted surface and violet edges. These fluorites are unique in the world and thus make specimens from the Rufibach cleft unmistakable and extremely popular with collectors. The entire fissure system is now so unstable that further work is no longer possible. As a result, pieces of this famous find are rarely, if ever, seen on the market. 
 The offered specimen adorns  Fluorite crystal of 18 mm on the edge with the typical features of the Rufibach cleft from the Zingenstock. The smoky quartz is water clear, sharp-edged and long-prismatic. On both sides of the specimen, the crystals are intact. Two crystals have frost cracks which form inside the crystal when the piece is exposed to frost and thaw cycles. 
 High contrast, aesthetic and hard to find classic from the  Swiss Alps.
