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. A mark of authenticity, the inscription and accompanying documentation delivers an important assurance on the chain of custody from the mine to the point of purchase, that the gem has always been in the care of Argyle Pink Diamonds™ and its trusted trade partners.
Gem Analysis Service
From January 2024, Argyle Pink Diamonds™ commenced a programme whereby it will work exclusively with renowned independent laboratory, Gemlab (Belgium) BV, who will undertake an analysis process using current scientific knowledge and proprietary techniques to identify pink, red, blue or violet diamonds that exhibit characteristics corresponding to those present in diamonds from the Argyle Diamond Mine. Where the analysis identifies the presence of such characteristics, to a reasonable degree of confidence, Argyle Pink Diamonds™ will inscribe those diamonds with a unique lot number (visible only under magnification) and issue the diamond with an Argyle Pink Diamonds™ Gem Analysis Report.
Note: This form of certification differs from diamonds issued with an original Argyle Pink Diamonds™ Gem Identification and Authenticity Certificate, which were sold through our secure chain of custody. Please click here for conditions applicable to this programme.
