This is a vintage ring I purchased at a vintage shop for about 8,000 yen. The inner diameter is about 15mm, but it has some room even on a finger that usually wears an size 8 ring, so I think it's about a size 10. Please note that I cannot determine the exact size because the part that goes on the finger is not a perfect circle. The ring is silver, but it is unknown whether it is silver 925. There is a stone in the middle, which is a dark purple color. ★ I have many accessories for sale. I will offer a discount for bulk purchases, so please let me know in the comments.
