This is a Jouete 18k diamond yellow gold necklace!! I purchased it at Jouete in Sapporo Stellar Place in August 2024!! Retail price: 59,400 yen Certificate of authenticity included! I've used it a few times, but I'm selling it because I don't have many opportunities to wear it. Please refrain from purchasing if you are sensitive to the fact that it is not brand new and has been stored at home! It's still in great condition, so please consider buying it☺ From the official website: "K18 Diamond" necklace with a simple, uncluttered design that maximizes the brilliance of the diamond. This classic single-diamond necklace is a must-have and can be worn timelessly by all generations. The design features eight prongs arranged like petals. The diamond topping the delicate cut chain gives a delicate impression and will brighten your mood. The soft texture unique to K18 material brightens the neckline and gives a calm, elegant look. It is a luxurious item filled with the charm of jewelry. Accessory material: Yellow gold (18k) Accessory decoration: Diamond (0.06ct)
