Nothing like these have been found anywhere besides the Shijiangshan mine, Pink Bultfonteinite is a rare thing anywhere, Bultfonteinite has only been found in 4 locations globally, collectable specimens mainly in South Africa, and Shijiangshan. The combination with Imayoshiite (albeit small on this piece) makes it very special. The white fibres – and this is an educated guess – are most likely Shinichengite.
