18k French Filagree Link Chain

I bought this chain from a French dealer, if memory serves me correctly, and oo la la! Elle est belle, n'est-ce pas? This stunning filagree chain is 18k yellow gold, measuring 23.5" long and 6mm wide. The clasp is a bit discolored, but it passed a 18k acid test. That said, if you would want it replaced, I am happy to do so for an additional charge. The piece weighs 11.11 grams.
