Natural Diamond Guarantee


100% Natural, Conflict-Free Diamonds - Our Guarantee

Every diamond we sell no matter how big or small is certified natural and conflict-free in compliance with the Patriot Act, the Kimberley Process, and United Nations resolutions. Our internal guidelines exceed these government requirements: we have binding contracts with our suppliers and trading partners which guarantee that the diamonds they offer to us for sale comply with all applicable laws and are certified natural mined and conflict-free.

Overnight Guarantees that any and all diamonds sold are exclusively of natural origin based on personal knowledge and/or written guarantees provided by the suppliers of these diamonds. Additionally, Overnight tests each parcel of diamonds they receive twice, using the most advanced testing methods and technology to ensure that each stone is Natural.

Kimberley Process Compliance and America's Patriot Act

The Kimberley Process Certification Scheme (KPCS) was established by the United Nations General Assembly in 2003 to preclude diamonds associated with conflict from entering the diamond market. All KPCS Governments must certify that rough diamonds derive from sources known to be conflict-free. To extend the KPCS to polished diamonds, the World Diamond Council established a System of Warranties to guarantee that polished diamonds derive from a conflict-free rough source. Polished diamonds sold in the U.S. must adhere to the Patriot Act and sanctions by the US Treasury’s Office of Foreign Assets Control. Every U.S. dealer must maintain Kimberley compliance or be subject to penalties from Homeland Security, the U.S. Justice Department, and the U.S. Treasury.
