Tiffany Mint 1837 Silver 3 Blue Sapphire Circle Round Stacking Ring Band Size 6

Authentic Tiffany’s Sapphire & Sterling Silver Ring (was bought around 2008). Was gifted by a prior boyfriend and although beautiful, I’m married and don’t need it. The exact name is “Tiffany Mint 1837 Silver 3 Blue Sapphire Circle Round Stacking Ring Band Size 6” Due to it being a gift I do not have the proof of purchase but I can go to Tiffany’s and ask them to authenticate if you’d like. Could use a good cleaning but Tiffany’s provides free cleaning on their jewelry - so you can take it into any boutique Reasonable offers welcome
