Thank you for contacting Mearto with your appraisal inquiry, and I apologize for the delay. This is a beautiful and uniquely styled necklace. It appears to be in excellent condition, with only some light dulling of the polish from handling. The stones and pearls appear to be in good shape, with no wear present, and the settings are sound. Given the condition of this piece, and completed auctions of similar items, a fair market estimation is 500-550 dollars. Please reach out with any questions.
