Tiffany Diamond Certificate and Full Lifetime Warranty
The Tiffany Diamond Certificate is issued by Tiffany & Co. to certify the authenticity and integrity of serialised Tiffany diamonds. This document contains vital statistics related to your diamond, from its grades based on the 4Cs to its unique laser-inscribed serial number.
Our Diamond Certificate is backed by a Full Lifetime Warranty, which guarantees the grade of your diamond. Other diamond reports, including those from the Gemological Institute of America (GIA), do not contain such guarantees and even carry disclaimers.
