Rio Tinto Unveils Argyle Pink Diamond Ring Worth $6 Million

Rio Tinto has showcased its first large Argyle Pink Diamonds jewellery item since the closure of Western Australia's historic Argyle mine: the A$6 million Argyle RomanticaTM ring, handmade with 3.42 carats of rare pink, red, and blue diamonds from the mine.

The Argyle Romantica is the first item to be created as part of the Argyle Pink Diamonds Icon Partner initiative, which is part of a plan to safeguard the origin of Argyle Pink Diamonds. The ring has five excellent Argyle Pink Diamonds weighing a total of 2.31 carats, including a 0.75-carat fancy red diamond, two fancy vivid purplish-pink diamonds, and two fancy deep pink diamonds. The five main red and pink diamonds are set in an elaborate setting with 1.11 carats of smaller blue and pink Argyle diamonds.

The Argyle Romantica, designed by Singapore-based rare gem specialist John Glajz, pays homage to the whole variety of romantic colours of Argyle Pink Diamonds, as well as the endless beauty and mysticism of these prized stones. "Encapsulating a rich history and exceptional pedigree, the Argyle Romantica is a work of art and an heirloom for future," stated John Glajz. "We look forward to continuing to collaborate with our downstream strategic partners to develop new masterpieces that sustain the heritage of this great Australian brand," said Rio Tinto Minerals Chief Executive Sinead Kaufman.

As part of their 80th anniversary festivities, the Argyle RomanticaTM will be presented in Sydney and sold through renowned Argyle Pink Diamonds Select Atelier, J. Farren Price.


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.
