Just mention Knappenwand to any serious mineral collector and they will think Epidote. This is one of the world's best localities for wonderful Epidote specimens and this classy example is a total beauty. Dark bottle-green Epidote crystals to at least 5 cm long form an interlaced cross-work of parallel blades, all perfectly terminated and with a bright glassy lustre. Encrusting these in many areas are micro crystals of opaque, pistachio green Epidote. Overgrowing the Epidote crystals are dense mats of peppermint green to pale sea-blue-green Byssolite, a hair-like acicular variety of Actinolite. The deep-lime to bottle-green Epidote crystals grade from transparent to opaque. This is a wonderful, museum quality specimen from the Alpine epidote-amphibolite clefts in the Knappenwand of the Untersulzbach Valley, Salzburg, Austria.
