This item was purchased from the accessory brand Arpege. They used to have a shop in Takashimaya's accessory section, but it seems they no longer have a physical store. It's a K10 pink gold necklace and a double-strand bracelet, also in K10 pink gold. The necklace chain is broken, as shown in photos 17, 18, and 19. It's currently shortened and connected to the adjustment ring, so it can still be worn at its shortest length of about 35.5cm. Both items have an "S" charm. The "S" charm on the necklace has stones in it, although they are difficult to see. The bracelet has stones on one chain and the "S" charm on the other. - Material: K10 pink gold - Length: Necklace approximately 35.5cm, Bracelet approximately 17cm Thank you for looking.
