Have you ever wondered how we authenticate our Tiffany & Co rings? The honest truth is that it's a bit complicated. Experience is a key factor but we also use technology. Here is a photo of a laser inscription on the facet of a Tiffany & Co diamond, taken with our powerful microscope.

You can see the inscription clearly enough to make out the number, which corresponds with the diamond certificate.

You can ask us for one of these photographs by request on any of our Tiffany & Co engagement rings. Please note that rings which were manufactured before 2004/5 will not be engraved. We will let you know if this is the case.
