A rich miniature-sized specimen of incredible aesthetic and scientific quality. This piece features INDIVIDUAL and ISOLATED , RELATIVELY LARGE crystals of Francevillite to several mm in size, on an attractive matrix plate - and the back side is as good as the front side! Tiny yellow-gemmy crystals of mounanaite are so abundant and rich on this specimen that they are easily eye-visible against the larger francevillites, as shown in my pics. Characteristically powdery microcrystals of orangey-yellow curienite are in association , as well. This mine closed in 1999 after 40 years of production, and this is, for quality if not size, pretty much as good as the mineral gets. It is a trim from the large specimen I obtained, below. Note that this its the type locality of ALL THREE species! 4 x 3.5 x 1 cm
