Wonderful thin 18K yellow gold and lapis lazuli Art Nouveau slip-on bangle bracelet. The bangle is less than 1/8" W and at the lapis about 1/4" W. The bangle weighs 9.3. The diameter measured on the inside is over 2 1/2". We were told the stones are lapis with gold flakes but we have not had them tested. They are all domes and nicely matched. The gold work on the bangle is mostly flowers and even more lovely when louped. There are no marks but the bangle has been tested to be 18K. Great stacking bangle or understated beauty if worn alone.
