Superb, large, very well-crystallized specimen of yellow-green francevillite and yellow vanuralite crystal aggregates from the famous Mounana Mine, Mounana, Léboumbi-Leyou Department, Haut-Ogooué Province, Gabon. This “style” of crystallized francevillite is quite rare, especially in cabinet-size, undamaged examples. This is one of the best I have seen, with fantastic coverage and no damage to speak of. Excellent Mounana mine specimen! Eric Quinter specimen U/Th 0954, pictured on Mindat.org.
