I purchased this from an accessory shop last year for 200,000 yen. I am selling it because the bracelet was too small and I couldn't wear it. I was told it helps with stiff shoulders and makes your body feel lighter. I will sell it at a bargain price. Necklace: 48cm Bracelet: 16cm It sparkles beautifully. The condition is good, and I haven't used it much. There is no box or certificate of authenticity, and I don't know what kind of stone it is. No returns, no claims accepted.
