Sinclair, along with the global diamond industry, has a zero-tolerance policy toward conflict diamonds. The Kimberley Process tracks diamonds from mine to market, and the industry in partnership with the United Nations, governments, and non-governmental organizations, polices diamond exports to prevent the trade of illegal diamonds. We only purchase diamonds through the most respected suppliers who strictly adhere to and enforce the standards established by the Kimberley Process. All Sinclair diamonds are warranted to be conflict free and are ethically mined.
Diamonds are mined throughout the world, including major mines in Australia, Africa, Russia and Canada. Diamonds are a major source of good in many African nations, employing and providing healthcare to thousands.
The Kimberley Process is an international process to track and certify diamonds. In April 2003, the US Congress and President Bush passed a law adopting the Kimberley Process that requires all US diamond retailers to buy diamonds from manufacturers who have documentation warranting that the merchandise was obtained through legitimate channels. Today, the US Customs Service actively enforces the Kimberley Process requirements as diamonds enter American ports.
Grading Reports serve as description of a diamond based on the '4 Cs' and additional specifications.
Gemstone Certificates and Diamond Grading Reports are not a valuation, appraisal or representation of warranty. They are simply a description of the grading, testing, and identifying characteristics observed in the gemstone based upon the analysis techniques and equipment used at the time of examination. Rubies, sapphires and emeralds could have minor or moderate enhancements in their appearance.
