Founded by Mike Angenent, Open Source Minerals is a highly respected organization in the the ethical sourcing community, specifically trading diamonds and gems that originate from legitimate sources unplagued by human rights abuses. Open Source Minerals resigned from The Responsible Jewellery Council in response tor RJC's stance in allowing diamonds in the Marange fields of Zimbabwe.
RJC has moved to back decision of the Kimberley Certification Process (KP) to certify the Marange diamonds, mined in Marange fields in which several human rights violations have been documented.
