Our diamonds reflect your life’s journey. Whether marking a new chapter in your story or celebrating an important milestone, you can upgrade your Tiffany & Co. diamond designs with the Tiffany Diamond Promise.


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.
