JB (maker untraced), a bloodstone set silver choker necklace, London 1973, stamped makers mark ‘JB‘ in a shield, cabochon agate 1.9 cm by 1.4 cm, inner diameter approximately 11.9 cm SOLD
This is similar in design to chokers produced by Daedalus Ltd of London that I have seen, however as I am unaware of who this is I cannot make any association between this maker and them.
