An impressive large carnallite crystal from the classic German potash locality of Wathlingen, renowned for high-quality evaporite minerals. The specimen displays a natural, well-developed crystal form with a characteristic vitreous to greasy luster and a translucent to locally transparent structure. The typical coloration — ranging from pale through honey-yellow to slightly reddish — reflects its natural origin within evaporitic salt deposits. Carnallite (KMgCl₃·6H₂O) rarely occurs as large, well-formed crystals, as it is usually found in massive form and is strongly hygroscopic. The preservation of a distinct, large collectible crystal required favorable conditions and careful handling, making this specimen particularly desirable for collectors of evaporite minerals and classic German localities. The specimen stands out for its size, natural character, and clearly visible crystal structure. A decorative and uncommon piece in this size — ideal for an advanced mineral collection or as a representative specimen from historic German potash deposits. specimen comes from old collection. Ex. H. Wunkhaus, acquired in 1988.
