I love this ring. Congratulations, it's just beautiful!
My husband and I decided to get it for our third anniversary. We were debating different center stones and carat weight (diamond, pink sapphire and aquamarine) and were quite pleasantly suprised by relatively reasonable prices of the aqaumarine legacy setting.
Plus Tiffany's does interest free financing for 6 to 9 months which, I think, is great. Lastly, their service is simply outstanding -- they are No. 1 and totally worth the money.
