A classic old-time specimen from the Mojina Mine, Buenaventura Municipality, Chihuahua, Mexico.
Beautiful pale blue Celestine and white Calcite are intergrown to form radiating finger-like groups of crystals. The upper display side of the largest group fluoresces a neon-green, indicative of a thin coating of hyalite opal.
These specimens were collected many years ago and are nowadays rarely seen. A true rarity.
