An outstanding specimen from this important locality, featuring seemingly terminated cherry-red villiaumite crystals in a cluster. Although beautiful and seemingly cubic, most specimens of villiaumite of any size are simply cleavage fragments, as a customer pointed out to me. This showy piece may have terminated faces on the front of the piece, however, at least. Villiaumite is a rare sodium fluoride.
