ILA goes a step above the Kimberly Process and purchases our diamonds primarily from De Beers Global Sightholders (formerly known as Diamond Trading Company).  As a sightholder they are contractually obliged to abide by the De Beers Best Practice Principles (BPP) and audited annually.  The BPP Assurance Programme provides evidence to supply chain partners, consumers and other interested stakeholders that the exploration, extraction, sorting, cutting and polishing owned or controlled by the De Beers Group of Companies and by their Sightholders, are undertaken in a professional, ethical and environmentally friendly and accountable way. Critically, BPP provides a means of checking compliance with requirements relating to anti-money laundering and terrorism financing activities, as well as independent monitoring to ensure that the obligations of the Kimberley Process are satisfied.  The BPP Requirements incorporate best practice measuring and reporting standards, such as the standard of Social Accountability International (SA8000) and the Global Reporting Initiative (GRI). The sightholder status allows them to source rough diamonds from responsible mines in Canada, Botswana, Namibia, South Africa, and Russia, which we purchase after they have been cut and polished.

The sightholder status of the ILA diamond factories allows them to source rough diamonds from responsible mines in Canada, Botswana, Namibia, South Africa, and Russia, which we purchase after they have been cut and polished.

Our natural diamonds are rigorously assorted to have exacting brilliance and to fall within our tolerance for color and clarity.  Our made to order engagement rings are crafted with your choice of GIA certified diamonds.  GIA, or the Gemological Institute of America, has the strictest standards of any laboratory and is ILA's choice of certification.
