Memberships

Argyle Pink Select Atelier 

Hartmann’s has held the title of Argyle Pink Select Atelier since 2008.

The title is awarded by Rio Tinto, the mining company behind the beautiful and rare Argyle Pink diamonds, and there are just a few select jewellers around the world who carry this title – and only three in Europe.

With the title comes the opportunity to bid on the year’s very best coloured diamonds at the exclusive Hong Kong diamond auction – Argyle Pink Diamonds Tender.
