Excellent specimen of Romanechite after Gypsum crystals, formed beautifully inside a geode-like cast formation, at the back you can see the prints left by the Gypsym crystals. These type of crystallizations and pseudomorphs are typical for the classic locality but are scarse, especially in this superb quality that this specimen exhibits
