Alpine cleft minerals
Across the Swiss Alps, tectonic fissures opened during Alpine metamorphism became lined with slowly grown crystals — a centuries-old tradition of Strahlen (crystal hunting). Famous valleys in Graubünden, Valais, and Uri have produced superb specimens.
What collectors look for
Smoky quartz (including the twisted "gwindel" habit), pink and rose fluorite octahedra, titanite, hematite rosettes, and anatase are the signature Alpine cleft minerals.
