The diamond industry has made significant progress in ensuring that natural diamond is conflict-free and ethically sourced. 99% of natural diamonds are considered conflict-free. However, some diamonds marketed as “conflict-free” are not ethically sourced. A lack of accountability in the diamond supply chain makes it difficult to determine that a stone is ethically sourced. Many GIA certificates don’t show the diamonds origin. The best way to ensure a diamond is conflict-free and ethically sourced is to buy mine-to-market diamonds. Lab created stones are often marketed as ‘ethical alternatives’ but be mindful that natural diamond mining still contributes to the development of communities and economies around the world.
