Purchased at a domestic AHKAH store. This is the Mosaic Brilliance Ring. I haven't worn it on a daily basis. I've used it a few times for a short period. It has been stored in a jewelry box at home. The metal is K18 white gold, and the stones are diamonds. The price listed in the image is for platinum. The latest retail price is around 270,000 yen. I understand that size adjustments of +1 or -1 are possible, but I'm not sure until you consult with the store. Please consult with an AHKAH store for maintenance. Size: 8, 9, 10 Material: White Gold Size: 9 Stone: Diamond Accessories: Box, Warranty Scratches/Discoloration: None The retail price is also increasing, so this is a very good deal, and I would appreciate it if you could refrain from price negotiations. Other jewelry brands are also experiencing price increases.
