Mounana Mine (Mouana Mine), Franceville, Haut-Ogooué Province, Gabon

    Francevillite is one of those nifty Uranium minerals that combines all sorts of other elements in its molecular structure. Besides the Uranium, there's Vanadium, Barium, Lead, Oxygen, and even a few molecules of water. As is the case with other Uranium minerals, this Francevillite is rather colorful, showing an unusual, olive-green sparkling druzy surface over a bright canary yellow interior of bladed radiating crystals. The Francevillite covers a large [4.7 x 4.7 inches (11.9 x 11.9 cm)] area of the gray matrix slab. There are a few minor dings to the coating, but the general condition is excellent. This piece was originally in the collection of the Mineralogy Department of the Sorbonne. There is an accession number on the bottom "7029," which corresponds to the number on the Sorbonne Collection label.
    Overall Measurements: 4.7 x 4.84 x 1.7 inches (11.94 x 12.3 x 4.32 cm)
    Offered at no reserve.

    Provenance: Luis Leite, ex. Sorbonne Collection [Hoppel #D1198]

    Estimate: $4,000 - $5,000.
