Does my engagement ring come with a Lifetime Warranty?

Yes, the Tiffany Diamond Certificate is backed by a Full Lifetime Warranty, which is our written promise that the information on the Tiffany Diamond Certificate is true at the point of sale. The warranty states that if, at any point in the life of the purchaser, it is ever discovered that the diamond differs in quality from what the Tiffany Diamond Certificate states at the time of purchase, Tiffany will either offer a full refund or replace the diamond with a diamond matching the correct quality stated on the certificate or better.
