What are Argyle origin pink diamonds and why you should avoid them?
The majority of Rio Tinto Diamonds’ (RTD) Argyle 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 products.
A full range of rough diamonds is offered to a global group of diamond companies through an auction-based sales channel: Specials & Coloured Rough Tender: Two times per year, RTD offers pink coloured rough from the Argyle diamond mine production.

This is completed via a sealed bid, first price auction system, customers can buy high-value large single stones, parcels of rough diamonds consisting of a diverse range of sizes, shapes and qualities in a variety of colours from light pinkish to dark pink.
The Argyle mine only retain the top end of the pink diamond rough for the prestigious Argyle brand, the remaining pink diamond rough that did not meet the specified standards set by the Argyle brand were subsequently submitted for auction.
After being cut and polished, these pink diamonds are frequently sold with an Argyle origin certificate verified by an independent diamond laboratory such as the GIA.
remember
Although they may be from Argyle origin, they will never have the same financial growth, rarity or prestige as an authentic Argyle branded pink diamond.
