The majority of Rio Tinto Diamonds' (RTD) rough production is sold directly through regular contract sales to a selected group of core customers, known as Select Diamantaires.
RTD also conducts Alternative Sales, by invitation only, providing non-Select Diamantaires with the opportunity to access Rio Tinto product; a full range of rough diamonds is offered to a global group of diamond companies through two auction-based sales channels:
- Invitation Sales: five times per year, RTD offers a broad mix of premium Canadian (Diavik) and Australian (Argyle) rough, ranging from -5 sieve size up to 10 caraters, in different models, qualities and colours. Via a transparent, dynamic and user-friendly auction system, customers can buy consistent parcels at market determined prices.
- Specials & Coloured Rough Tender: two times per year, RTD offers large (mainly +10.8ct) and fancy coloured rough diamonds from the Argyle and Diavik productions. Via a sealed bid, first price auction system, customers can buy high-value large single stones, parcels and natural coloured rough diamonds comprising a diverse range of sizes, shapes and qualities in a variety of colours, including pinks and fancy yellows.
