We are only able to provide assurances regarding provenance for polished diamonds that were inscribed and issued with a certificate by Argyle Pink Diamonds™, after being sold through our secure chain of custody.

From January 2005, each Argyle Pink Diamond™ over 0.20 carats was laser inscribed with a unique lot number and issued with an Argyle Pink Diamonds™ Gem Identification and Authenticity Document. From January 2009, this programme extended to diamonds over 0.15 carats, and from December 2016, all Argyle Pink Diamonds™ over 0.08 carats were inscribed and certified. This unique lot number is recorded within our Diamond Check Service, and is able to be searched here.

If you are searching for a number that does not appear in our Diamond Check Service, this means that the number does not correspond with our database of diamonds inscribed and issued with a certificate by Argyle Pink Diamonds™. Unfortunately, we are not able to provide any subsequent verification of provenance in such circumstances. Should you have any queries or wish to report fraudulent documentation, please contact enquiries@argylepinkdiamonds.com.

Argyle Pink Diamonds™ is unable to repurchase or assist in the resale for diamonds already sold, or jewellery in which the diamonds may be set. For trade or retail assistance in these enquiries, please contact an Argyle Pink Diamonds Select Atelier™ or Authorised Partner™.

Gem identification documents are only issued for Argyle Pink Diamonds™ which are laser inscribed with a unique number. The number, if present on the stone, can be viewed through a 10x magnification on the girdle of the diamond. This number is only applied to diamonds of a minimum carat size. A gem identification document should accompany the sale of the diamond. To protect the integrity of the gem identification document, duplicate documents are no longer issued. To verify the details of a laser inscribed diamond, please refer to the Diamond Check service on this website.
