Manjian Design Works is committed to The Kimberley Process Certification Scheme, an international government scheme that works to end the trade of unethically sourced diamonds. 

The program requires that governments certify and track shipments of rough diamonds, which have been sourced legally. Participating countries must enact national legislation around diamond export, import and trade controls. Transparency and the exchange of statistical data is also essential to this scheme.

This is the most effective way for our studio to guarantee that every diamond we come into contact with has not been sourced through unconscionable means. ... Because Manjian Design Works is an ethical, principled business.
