DESCRIPTION: A rare vintage sterling silver genuine blue john doublet scarf ring, made from sterling silver. It weighs approx. 7.25g and the size dimensions are in the later photos. It's stamped "SILV". Blue john is an extremely rare mineral and can only be found in Derbyshire in the UK (not far from me), it's infact Britain's rarest mineral. PLEASE NOTE: The blue john doublet has some fogging on one side, see pictures/video. I've reduced the price accordingly.
