A small chip with bright blue crystals of this recently described new IMA mineral from Ojuela. Once thought to be Claringbullite. This specimen came off of what was probably the type specimen, which was obtained by me several years ago in Denver and shown to be Claringbullite by XRD. Later EDS showed it to be a new mineral. See Ferjerite at RRUFF.
