Thank you for submitting your item for appraisal. This appears to be an art deco style three row cultured pearl bracelet with a large natural emerald cabochon, surrounded by brilliant cut diamonds, connected to three part hemispheres set with diamonds. Naturally it is difficult to appraise the quality of the stones just from a photo. The estimate is based on similar sold at auction. "Asking prices" in the trade can be higher and vary.
