This is a natural stone silver necklace from mami, which has a shop in Kichijoji. I received it as a gift, so I don't know the type of stone, but I think it's a natural stone because they seem to sell natural stone rings of the same design (photo ⑦). Both the top and chain have silver markings. The top has dirt on the back that didn't come off even when wiped with chamois leather. It might come off with silver cleaner. Chain length: Approximately 38.5cm Pendant top: Approximately 12mm How about it if you want an accessory that's not like everyone else's? #mami #Kichijoji #MamiKitahara #naturalstone #silver #necklace #silveraccessory #silvernecklace #naturalstonenecklace #women's
