Diamond Sales and Marketing

Rio Tinto Diamonds’ business model is to work with a network of partners – diamantaires, manufacturers, designers and retailers – to bring diamond consumers innovative products that they can trust.

Rio Tinto is headquartered in London with a sales and marketing support office in Antwerp and representative offices in India, the United States and Hong Kong to maintain close and regular contact with key markets. This helps Rio Tinto to better understand its operating environments and support their ongoing development. For example, it is estimated that at least two-thirds of Rio Tinto's diamond production by value is manufactured in India, where some 250,000 workers are engaged in diamond manufacturing. Rio Tinto’s Indian office in Mumbai has been operating since 1989, providing diamond traders, jewellery manufacturers and exporters with sales and technical support, including assistance to develop superior diamond cutting skills. Rio Tinto has also introduced initiatives to help improve the industry's practices in relation to health, safety, quality management and environmental and social responsibility.

Rio Tinto’s representative office in New York (opened in 2007) directly supports customers in the United States – the world’s largest retail diamond jewellery market – while the Hong Kong office (opened in 2010) provides an active presence in China, the world's fastest growing consumer market for diamonds. The niche Argyle Pink Diamonds business, which cuts and polished the rarest pink diamonds in the world, is located in Perth, Western Australia.
