Queens Jewelers upholds strict ethical standards, particularly those regarding sourcing. Each of our diamonds sold in jewelry settings is in full compliance with the certification system of the Kimberley Process, as defined by the United Nations. Under the guarantee system instituted by this process, each partner provides a certificate that attests the sourcing of diamonds from non-conflict countries. This ensures the credibility of diamond trade, eradicating the circulation of stones from countries in situations of armed conflict.
