Old true victorian era condition unusual bead style, thumbnail grab old clasp style, hard to find the little button but it's there to feel and open after you look at it, old nice working, rolled gold clasp silver chain and rustic beads i've not seen this type before, gorgeous old unknown untested matte heavy trade style beads, the only reason these are in tact so well is due to the chain a string would not have kept well, i don't see any hallmarks, clasp has mild pitting of age so lovely and substantial, at about 21 all around open measure.
