Description

A sizeable matrix vesuvianite on the typical green-grey metasomatic matrix, associated to idiomorphic candid white davyne.
Vesuvianite is a tabular 'cogwheel' perched atop a drusy of davyne, with numerous exceptionally lustrous faces.
Upon strong illumination, some crystals are locally transparent. Vesuvianite predominantly populates the outskirts of a metasomatic vein. This gives a very esthetic display to the specimen.
Quite rich and good for Vesuvius, very rare to find at shows on this size nowadays.

Former collection and stock Bruno Cerato (Italy).
