Yellow Pink Diamond Ring From Rio Tinto Diamond Mines.

In Sydney, a one-of-a-kind yellow and pink diamond ring showcasing the finest gems from Rio Tinto's Australian diamond mines was unveiled. The Diavik Midnight SunTM is a powerful symbol of the union of two of the world's most coveted jewels: yellow diamonds from Rio Tinto's Diavik diamond mine in sub-Arctic Canada and Argyle Pink DiamondsTM from the iconic mine in Western Australia's remote East Kimberley region.

The Diavik Midnight Sun is inspired by the amazing natural phenomena that happens when the sun is visible in the Arctic at midnight, displaying lovely golden and pink colours. The Diavik Midnight Sun is centred on an 18.08 carat fancy intense yellow oval Diavik diamond, one of the finest large yellow diamonds discovered in the Diavik mine in the last 20 years. The Diavik yellow diamond, which weighed 36.75 carats as a rough diamond, is vividly contrasted with an intricate setting of rare Argyle pink diamonds totaling 4.09 carats.

As part of Rio Tinto's Icon Partner programme, the Diavik Midnight Sun is a collaboration between Rio Tinto, luxury jeweller Musson, a trusted Argyle Pink Diamonds Select AtelierTM, and rare gem specialist Glajz THG. Musson jewellers and Glajz THG have a long history of working with Rio Tinto's diamonds, sharing a love of craftsmanship and pedigree. Musson is selling the Diavik Midnight Sun ring for A$1.85 million as part of their 50th anniversary celebrations.

"This combination of a rare yellow Diavik diamond and Argyle Pink Diamonds, the rarest diamonds in the world, is a special moment in the history of Rio Tinto's unique place in the natural fancy coloured diamond industry," said Patrick Coppens, Rio Tinto's General Manager of Sales and Marketing for its diamonds business.

Musson are expert artisans who have caught the captivating colour and light of these fascinating jewels in their one-of-a-kind jewellery creation." The Diavik diamond mine, which has been in operation since 2003, mostly produces white gem quality diamonds, with yellow diamonds accounting for less than 1% of total production. Rio Tinto's Argyle diamond mine produced nearly all of the world's rare pink diamond production until it closed in 2020. With no new pink diamond supply sources in the world, Rio Tinto has retained the Argyle Pink Diamonds brand for continued market development, which includes actively working with downstream partners on jewellery creations to preserve the brand's legacy and precious provenance.


Billionaire Laurence Graff paid a record-breaking $46.1 million for a magnificent vivid pink diamond weighing 24.78 carats. Originally owned by his competitor Harry Winston, it now carries graff’s name and is a part of the legendary collection of rare diamonds.

We usually advise brilliant round diamonds with a cut grade of very good, ideal, or super ideal for engagement rings (also known as hearts and arrows). A high cut grade maximises a diamond’s beauty for a given carat weight.
