Description

New find of very glossy brown jarosite crystals on matrix from an obscure locality, a new mine run by a friend of ours. The jarosite has been analyzed,  the blue part of the matrix is a thin sheet of iridescent iron-oxide, probably hematite, goethite or turgite (a mix of both). You can only get this material from us (there's not much).
