Stone: Peridot Material: K18WG (18k White Gold) A refreshing necklace with olive green peridot. The peridot has a checkerboard cut, giving it a sparkling and elegant shine. Length: 7mm, Width: 5mm Chain: 40cm I've forgotten the brand name. There is a hallmark, but it's small and I can't read it well. Price is not negotiable. The price is firm due to the fees and shipping costs. No accessories included. The necklace will be packaged to prevent tangling or damage and shipped via Yu-Packet.
