This is a Torque ring designed by Frank Gehry. I believe I purchased it approximately 15 to 20 years ago at the Tiffany & Co. Ginza store. It has a wide band and a strong presence. It would also look good on a man. Additionally, it's a ring that's easy to combine with bangles and other accessories for the upcoming season. Size: Approximately size 13 (Japanese ring size) Ring width: Approximately 1.1cm The material should be stone. I don't remember the specific type of stone. I have other rings made of silver and gold for sale, but I don't see any other stone rings, so I think this is a very rare item. I used it occasionally after purchasing it, but recently I've been using other rings more often, so I've been storing it in my jewelry box. There are no noticeable scratches. I remember the color was white. Perhaps because time has passed since the purchase, the stone's brownish texture has become more noticeable. As it is a natural material, I hope to sell it to someone who can appreciate this change. I don't remember if it came with it at the time of purchase, but I will include the Tiffany & Co. storage pouch shown in the first photo.
