Description

Sharp crystal of tetragonal dipyramidal scheelite that has been completely replaced by black ferberite microcrystals, with some quartz and white mica on the surface at the rear side. It is a floater crystal, almost complete, with just a small portion missing at the rear (photo 3). It was collected at the end of the 70’s by Jacques Deblandre at the Bugarama pegmatite (Rwanda). This is the best one of three peaces he had in his collection. A superb and rare reinite pseudomorph!
