Bavenite and fluorite crystals from the Henneberg, Thuringia, Germany– cabinet specimen as unique piece
This cabinet specimen features a striking combination of delicate, fibrous Bavenite crystals with embedded violet-blue Fluorite cubes on a light granitic matrix. The crystal zone is richly textured: fine Bavenite aggregates alternate with lustrous Fluorite faces, producing a pleasing color interplay of white, violet, green, and ochre. The contrasting tones and balanced arrangement make this specimen a characteristic and aesthetic example from the classic pegmatite locality of Henneberg in Thuringia.
Geology & Origin
Bavenite is a rare silicate mineral from the zeolite group, forming secondarily through hydrothermal alteration of calcium silicates in granitic pegmatites. The Henneberg locality in Thuringia is one of the classic German occurrences, where Bavenite appears together with Fluorite, Chlorite, and Quartz. These associated minerals reflect the late-stage hydrothermal processes characteristic of pegmatitic environments.
