The original characteristics of Argyle Pink Diamonds™ of a particular size that are laser inscribed and sold since 2015 are searchable through the Diamond Check tool.

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

Our Gem Analysis Service, which commenced in January 2024, relies on proprietary scientific analysis undertaken by an external laboratory partner, to identify pink, red, blue or violet diamonds that exhibit characteristics corresponding to those exhibited by diamonds from the Argyle Diamond Mine, to a reasonable degree of confidence. Where the analysis has identified the presence of such characteristics, the diamond will be issued with an Argyle Pink Diamonds™ Gem Analysis Report. This diamond is then also able to be searched via the Diamond Check tool. Please click here for conditions applicable to this programme.

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.

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.
