Description

From the Kamiaba region, a very remote locality close to the border with Zambia, this specimen features a deep red rhombododecahedral almandine crystal with good definition of stepped and lustrous faces and net edges.

Collected before 1960, the specimen is from the stock of Robert Verdoodt, who was working in the laboratories of Union Minière du Haut-Katanga and evacuated to Belgium in 1960 after the beginning of the Congo crisis. Uncommon locality in collections, that has never been abundant at all.
