Very well defined Correianevesite crystals on matrix with a considerable size and quality in some areas on the sample, with a dark brown color, and with groups of pink Hureaulite crystals and dark green, almost black, botryoidal growths of Rockbridgeite. A recent study of the crystals from the Cigana Mine that in 2006 were identified as Reddingite has shown the discovery of this new and rare species. So, the old Reddingite from Cigana must be renamed as Correianevesite, being Cigana Mine, at Galiléia, the type locality. We’ll send a copy of the analysis of the original “Reddingite” to the buyer.
