It is a secret only a few know. The invisible Forevermark icon and unique identification number inscribed at the heart of every Forevermark diamond.

The process is secret too, using patented technology developed by the De Beers Group. At one-twentieth of a micron deep, the inscription is completely invisible to the naked eye and can only be seen with a special Forevermark viewer at a Forevermark jeweller. The Forevermark inscription does not affect the internal quality of the diamond in any way.

The inscription proves that each diamond has met Forevermark standards: standards of quality and integrity; the individual number indentifies it always to be uniquely yours.

Every Forevermark Diamond comes with its own identification card carrying its unique number.
