Vintage ring Size: Approximately size 10 (Japan) I usually wear a size 9 (Japan) on my ring finger, and I wore this on my middle finger, so the exact size is unclear. K18, with a hallmark inside the ring. It's small and difficult to see in the photo. The stones are diamond and red, possibly ruby? It's not clear. The vintage feel is stylish. No box included. The openwork design is retro. It's a lightweight ring, but it has a presence when worn. There is no appraisal certificate. Also, due to the high price, please refrain from purchasing if you are looking for perfection like a new product. For those who understand the characteristics of vintage items, For those who can confirm the photos and are satisfied, For those who understand that this is a used item, Thank you. I would appreciate it if you could purchase at the listed price. No price reduction. Thank you for viewing.
