This is a rare and aesthetic combination of olive-green prismatic stacked crystals of this phosphate, with a vitreous luster, accented by contrasting hureaulite atop. Tiny, lustrous, translucent, honey-yellow crystals of correianevesite form a stalactite like, rich growth of this rare species. These were originally described as reddingite crystals, another phosphate. Probably most of the "reddingites" from here are correianevesites (see and Correianevesite is an ultra-rare phosphate approved in 2007 and the Jocao pegmatite is the Type Locality. This mined-out and interesting granite pegmatite is well-known for producing numerous high quality phosphate specimens from the mid-1990s into the 2000s.
