A very fine twinned deep lilac specimen from the antique workings in County Durham. Note the outstanding fluorescence under LW. This is a nearly complete floater with just a cleave at the bottom right corner, which has surficial growth patterns indicating the cleave occurred in situ. . The notch in the top left edge appears to be a contact from another crystal. Otherwise in excellent shape.
