Diamond Ring Material: K18WG (stamped) Size: Size 12 Stone Size: Center 0.634, Sides 2 x 0.05 (stamped) Marquise-cut diamond center stone with small diamonds on both sides. Purchased at an event held by the Sadamatsu Group. A statement of purchase is available as a guarantee, but it cannot be provided as it contains personal information. No accessories are included, but if you wish, we can include a box (different from the one in the image) for an additional 500 yen. Elegant and simple design. Used approximately 20 times. I can no longer wear it due to a change in finger size, so I'm offering it to someone who can use it. There are minor scratches from use. Please refrain from purchasing if you are sensitive to used items.
