Authentic Tiffany & Co. Platinum white & pink Diamond engagement ring set.

GUC Tiffany & Co. Platinum and 18k rose gold Soleste white and pink Diamond engagement set. The engagement ring has 2 missing white diamonds on the band, see photo. My local jeweler said it would cost $600 to replace those 2 diamonds. Other than that, this set is in excellent condition. After having my son, I started wearing a plan band. We just celebrated 10yrs, so good juju. 🤣
