Description

Here is a unique association of vanadium minerals, from a one-time vein of bementite-goldmanite ore mined in 2004. Häggite from Gambatesa seems the only known occurrence in microscopic but well-formed, bladed black crystals for this rare vanadium hydroxide. A colorful patch nearby is made by canary-yellow coatings of pascoite overgrown by tiny, tabular, carmine red crystals of ansermetite.
