K10 chain ring with Paraiba tourmaline. Fish motif. There is no engraving, but I have included the product specifications from when I purchased it in the second image. The mirror finish makes scratches noticeable. I haven't used it much, but there are many scratches. I will sell it at a low price because it has scratches from rubbing against other rings. Original price: 29,000 yen It's a size 5, but I wore it on a size 4 finger. I haven't used it much.
