Conflict-Free Diamonds

A diamond should mark a moment worth remembering, never a cost carried by someone else. Every diamond we set, natural or lab-grown, comes from a responsible, conflict-free source.

Our commitment

Beyond the four Cs of cut, colour, clarity and carat, we hold every stone to a fifth standard: it must be conflict-free. We only work with established diamond suppliers who meet the international standards set out below.

Natural diamonds

Conflict diamonds, sometimes called blood diamonds, are rough diamonds used to finance armed conflict against legitimate governments. To keep them out of the market, governments, the diamond industry and civil society created the Kimberley Process Certification Scheme, which has regulated the international trade in rough diamonds since 2003. Rough diamonds crossing borders between participating countries must travel in sealed containers with a government-issued certificate.

Once diamonds leave the rough stage, the World Diamond Council System of Warranties carries that assurance forward. Each time the diamonds change hands, the seller declares on the invoice that they come from sources compliant with the Kimberley Process. We only buy natural diamonds from suppliers who work within both systems.

Lab-grown diamonds

Lab-grown diamonds are real diamonds. They have the same chemical composition, hardness and optical properties as mined diamonds, and they show the same fire and brilliance. The only difference is their origin: they are grown in a controlled environment using advanced technology, so they involve no mining and have a fully traceable history from the day they are created.

Independent grading

Every piece comes with an independent jewellery report card: from IGI (International Gemological Institute) for lab-grown diamonds and from HRD Antwerp for natural diamonds in earrings and bracelets. The natural centre diamond of a ring comes with its own diamond certificate from GIA (Gemological Institute of America) or IGI. The report documents the diamonds' characteristics, including carat weight, colour, clarity and, for lab-grown diamonds, their origin.

Small diamonds, such as those set in tennis bracelets, are not graded one by one; the report card describes the piece as a whole. This is standard across the jewellery industry.
