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.


This complimentary service is offered over the lifetime of your ring and not only ensures that your diamonds or gemstones are cleaned, it also includes routinely checking (every six months) that the stones are secure in their settings. With proper care, your Tiffany diamond ring will retain its beauty and character for many generations to come. Contact us or bring your ring to one of our stores for cleaning.
