Anhydrite crystals from Naica, Chihuahua, Mexico – small cabinet specimen as unique piece
This small cabinet specimen features a radiating cluster of colorless Anhydrite crystals with a distinct fibrous character. The main crystal is well formed, partially transparent, and accompanied by numerous smaller crystals protruding at various angles from the surface. The structure is clearly crystalline and remains stable despite its delicate appearance.
Anhydrite is an anhydrous calcium sulfate that forms primarily in evaporite deposits and readily transforms into gypsum upon contact with water. Specimens from Naica are known for their aesthetic crystal formations, although such well-preserved and clear examples are relatively rare.
Geology & Origin:
Naica in the Mexican state of Chihuahua is one of the world’s most renowned localities for sulfate and carbonate minerals. Its hydrothermal veins and cavities were created by complex volcanic processes, resulting in the formation of exceptional crystals such as gypsum, selenite, and anhydrite. The locality continues to yield both scientifically and visually remarkable mineral specimens.
