An extremely delicate specimen of gypsum. It consists of a central, columnar crystal forming a vertical axis, from which smaller, transparent crystals of halite grow at various angles. Main features: co-occurrence of halite and gypsum; contrast between the orange-brown gypsum and the colorless halite. Condition: The specimen is very fragile, as evidenced by the loose deposits on the gypsum and the subtle structure of the halite, however, there are no visible mechanical damages.
