The document discusses De Beers' Supplier of Choice (SoC) program, which was launched in 2000 to drive consumer demand for diamonds by establishing term contracts and trade events called "sights" with selected distributors called "sightholders". SoC aimed to transition De Beers from a "Supplier of Last Resort" to a preferred supplier. In 2007, De Beers launched SoC 2 to address criticisms, foster more cooperative partnerships with sightholders, and increase ethical practices and transparency.
