The exportation (mailing) from the United States of any rough diamond (regardless of size, source, or value) is prohibited unless the rough diamond has been controlled through the Kimberley Process Certification Scheme. The Clean Diamond Trade Act of 2003 and Executive Order 13312 commit the U.S. government to the Kimberley Process Certification Scheme and establish the framework for how the U.S. government implements that commitment. The Rough Diamonds Control Regulations (31 CFR Part 592) set forth the legal obligations of U.S. rough diamond importers and exporters.
