Thank you for viewing. This is a K18 ruby and diamond ring. I bought it because I liked it, but I haven't worn it much and feel it no longer suits my age. The two small diamonds next to the ruby are not too flashy, making it a perfect ring for everyday wear. The inner diameter is just under 1.7cm, so I believe it's a size 12. I think it would also be lovely as a pinky ring. The estimated price on Mercari is 42,000 yen, so I think it's a good value. The box is not included. Please feel free to ask any questions. Thank you. Size: 12 Stone: Ruby
