Operating ethically builds consumer confidence in our product and our brand, supports our stakeholder relationships and helps us to achieve our business and development goals.

We work hard to embed ethical standards into every part of the diamond industry in partnership with governments, Sightholders, suppliers and contractors. This includes adhering to international codes of practice on conflict diamonds, following anti-corruption procedures and championing the ethical integrity of our people.

Diamond verification instruments developed by the DTC: the DiamondSure, which is used for rapid screening of diamonds for potential synthetics, the DiamondView, which generates fluorescence images from which synthetics can be identified, and the DiamondPLus, which is used to screen diamonds for potential High Pressure High Temperature (HPHT) treated diamonds.
