Conflict-free diamonds, also known as ethical diamonds, are diamonds that are mined and traded without funding armed conflict or human rights abuses. Buying conflict-free diamonds helps ensure that your purchase does not contribute to violence or human suffering.
The Kimberley Process Certification Scheme (KPCS) is an international certification system that aims to prevent conflict diamonds from entering the legitimate diamond trade. However, the KPCS has been criticized for being ineffective, and some conflict diamonds still manage to enter the supply chain.
