Chain of Custody
From January 2005, each Argyle Pink Diamond™ over a particular size was laser inscribed with a unique lot number, visible only under magnification, and issued with an Argyle Pink Diamonds™ Gem Identification and Authenticity Document. The inscription and accompanying documentation provides an important assurance of the diamond’s chain of custody from the mine to the point of purchase.
Gem Analysis Service
From January 2024, Argyle Pink Diamonds™ has worked exclusively with renowned independent laboratory, Gemlab (Belgium) BV. Gemlab undertakes an analysis process using current scientific knowledge and proprietary techniques to identify pink, red, blue or violet diamonds that exhibit characteristics corresponding to those found in diamonds from the Argyle Diamond Mine. Where the analysis identifies these characteristics to a high degree of confidence, Argyle Pink Diamonds™ will grade the diamond for colour and clarity, inscribe it with a unique lot number, visible only under magnification, and issue an Argyle Pink Diamonds™ Gem Analysis Report.
The Gem Analysis Service is accessible only by the eligible trade network of Argyle Pink Diamonds™ .
Note: This form of certification differs from diamonds issued with an original Argyle Pink Diamonds™ Gem Identification and Authenticity Certificate.
