Tiffany & Co. The Diamond Guarantee

Tiffany & Co. has a reputation to protect. Indeed, over the 175 years or so that Tiffany & Co. has been trading, protection against counterfeiting has always been high on the agenda.

In 2004, Tiffany & Co. started marking all engagement rings with individual identification numbers. These unique numbers are matched with the ring’s individual certificate and Tiffany & Co’s own records. When the number is called up by a Tiffany & Co. representative the exact details of the ring, type, diamond characteristics are recalled.

This should be enough! But Tiffany & Co. go further! They ensure that each diamond is laser inscribed with another number. This diamond identification number holds the unique details of that precise diamond! In addition, the diamond number is associated with the number on the ring in Tiffany & Co’s records.

Both numbers together provide consumers with the ultimate guarantee that an item is genuine. Only Tiffany & Co. will know what the numbers relate to and will print the information on their paperwork. Furthermore, the laser-inscribed diamond number can only be added with specialist diamond laboratory technology, making it very difficult to copy.

For those who buy pre-owned Tiffany & Co. engagement rings those two numbers provide re-assurance. Of course, there are rings that were made before 2004 that won’t carry the numbers. These rings can be identified through their outstanding workmanship + certificates, if there are any.

At Bloomsbury Manor our skilled jewelers are able to sort the wheat from the chaff, even without the serial numbers but we thought it would be great to share our knowledge with you, the consumer, by designing a Tiffany & Co. diamond guarantee diagram to help you understand what to look for when buying pre-owned Tiffany & Co. engagement rings. Remember that only one number is necessary for fool-proof identification but the two numbers together are infallible! What’s more, the diagram is in the shape of a diamond!!!
