by SharonRives » Jul 21, 2019 This ring was posted on my local buy sell trade group, with only these photos. I think it looks to possibly be a Soleste? Seller says it is hallmarked tiffany and pt950. I've asked for additional photos, and will go see it as soon as I can.. I've had luck buying several vintage Tiffany pieces through local groups, so hoping this one may be a solid risk = reward.
