The Kimberley Process Certification Scheme is the process designed to certify the origin of rough diamonds from sources, which are free of conflict funded by diamond production. The process was established in 2003 to prevent diamond sales from financing rebel movements.

The certification scheme aims at preventing "blood diamonds" from entering the mainstream rough diamond market. Joubi jewellery guarantees that it only uses conflict free diamonds from suppliers who trade within the Kimberly Process.
