Silver clasp type pendant. Closes with hoop over tongs. Grid pattern on inside of round end of tongs for gripping something (I assume). Stamp 925 on clasp of necklace and pendant, also archer like stamp on pendant. Was a Great Aunts and unfortunately I never got to learn its true use. Any information would be gratefully received. Pendant is 4 cm long and has a 'J' engraved on one side.
