Argyle pink diamonds are responsibly sourced under the standards of the Responsible Jewellery Council (RJC), for which Rio Tinto , the owner and operator of the Argyle Diamond Mine - is a founding member. Argyle Pink Diamonds fully adheres to the Principles and Code of Practice set out by the RJC.
Every company involved in this journey must adhere to the same fair-trade practices and international standards required by the Responsible Jewellery Council.
Once unearthed, each Argyle pink diamond over eight points (0.08cts) is authenticated with documentation and a unique lot number laser inscribed on the gem, visible only under magnification. The inscription and documentation represent an important guarantee on the chain of custody from the mine to the point of purchase, providing assurance that the gem has always been in the care of Argyle Pink Diamonds and its trusted trade partners.
Argyle pink diamonds over fifteen points purchased from 1 January 2009 can be verified via the Argyle Pink Diamonds Diamond Check Service.
Argyle Pink Diamonds was awarded the Butterfly Mark accreditation by Positive Luxury in 2017 in recognition of its leading sustainable practices and the careful custodianship of its diamonds throughout the supply chain, from the moment it is unearthed as a rough diamond, to the time it is offered for sale as a polished gem.
