Value guaranteed with Argyle mine certification

Each pink diamond from the Legacy Collection is laser inscribed with a unique Argyle ID number, visible under magnification. To accompany this, every stone is issued with a matching original Argyle Gem Identification and Authenticity Document.

The authenticity document gives you an assurance that the diamond originated from the Argyle mine and has always been in its own care, or that of trusted trade partners. So you get peace of mind that your pink diamond will retain and build on its value for many years to come.
