A CLASSIC, OLD-TIME natrolite specimen from the German Type Locality - Hohentwiel Mountain, Baden-Wurttemberg. Tan, radial aggregates of natrolite are found in a brecciated, gray host rock. This rich and showy old-timer comes from an old European collection, where everything dates to the 1800s. This whole collection had myriad old materials, though I cannot name the owner, and was well known in Europe. Accompanied by an old, handwritten German label.
