Rio Tinto has launched its inaugural sustainable jewellery collection. Titled Nature’s Beauty, the collection is made of gold from Rio Tinto’s Kennecott Utah Copper mine in the US, with white and champagne diamonds from Rio Tinto’s Argyle Diamond Mine in Australia.%% The Nature’s Beauty collection is a pilot project that will be trialled in the US, the world’s largest retail diamond jewellery market. Comprising earrings, rings, necklace and cuffs, the collection was showcased time for the first at the prestigious JCK Luxury show in Las Vegas.%% Rio Tinto has been at the vanguard of reform in the jewellery industry and results from consumer focus groups and quantitative research have revealed just how important the issue of sustainability is, in the eyes of jewellery consumers.%% Rio Tinto Diamonds chief commercial officer, Jean-Marc Lieberherr said, “Today’s consumer is looking for assurance that the jewellery they buy has been produced to the highest ethical, social and environmental standards.”%%
