Approximately 67cm! When worn around the neck, it's about 30cm long! The clasp is silver! My mother bought this at a boutique about 2-3 years ago, along with some clothes! The necklace alone cost 15,000 yen. Used only once for a wedding! It's a lovely length and very versatile! They say real pearls feel cold to the touch, and it certainly does feel cold... What do you think? I'm not an expert, so I'm offering it at this price. Please check the photos! I will ship it in the case! Please note that there are no instructions or anything else included. Thank you for your understanding!
