Argyle: a new kind of happily ever after

Argyle is closing, but its legacy will live on

Last updated: 10 December 2020


They are a fluke of nature and the ultimate in luxury, made in Australia.

Discovered in a dusty creek bed in Western Australia, today, Argyle diamonds can be found every place diamonds are loved – sparkling in jewellery store windows to royal palaces to weddings to prized collections.

“It’s hard enough to find a diamond deposit – but to get a treasure trove of pink, red, blue, violet, champagne and cognac diamonds, that’s really something else,” says Murray, a geologist, who has worked in our Diamonds team for 20 years.

“What we discovered at Argyle was an entirely new specimen of diamond. It changed diamond markets forever and showed coloured gems in a whole new light – not just the famous Argyle pinks, which represented less than 1% of production, but champagne and cognac gems too.

“When Argyle came on stream it virtually doubled world diamond production overnight and became the world’s largest producer of coloured diamonds,” Murray said.

Nearly 40 years and more than 865 million carats later, this year, we mined the last Argyle diamond. Today, the mine has begun its transition to closure.

“A huge part of the appeal of Argyle diamonds is their story – where they come from,” Murray said.

The story of all diamonds begins deep within the Earth, and at least a billion years ago – that’s about twice as old as life on dry land. Diamonds form from carbon that has been subjected to extremely high temperatures – around 1,100 degrees Celsius – and pressures over long periods of time. These conditions exist only at depths of 120-250km beneath the surface of the Earth, in a part of the planet known as the mantle.

“All diamonds start as white, but certain conditions – like pressure and stress – change their colour,” Murray says. “Pink diamonds are even more extraordinary because there’s a very small window when the heat and pressure turns them into the magnificent fancy pinks, reds, purples and blues Argyle is famous for. And right at that moment a volcanic eruption has brought them to the surface.

A new chapter

It’s not so much the end as a new beginning . Over the next five years we will rehabilitate the land before handing it back to its traditional custodians – the Miriuwung, Gidja, Malgnin and Wularr peoples.


Our mine closure plan outlines our approach to decommission the mine, reshape and rehabilitate the land, preserve ecological and cultural heritage values, and support future land uses by Traditional Owners such as cattle grazing and cultural tourism activities.

Feedback from Traditional Owners and regulators on the mine closure plan has provided valuable insights into developing our closure approach. Argyle has also worked closely with the local East Kimberley communities, businesses and government to understand the impacts of closure and prepare communities for transition after almost four decades of mining.

Argyle represents not only an extraordinary geological phenomenon, but a unique story of breaking moulds and challenging stereotypes.

From the beginning there was the challenge of attracting attention to an unusually high proportion of small, coloured diamonds, almost all in what are now known as the champagne colours and in strong demand in fashion jewellery in all major markets around the world.

At the other end of the coloured diamond spectrum, the strong market reaction in 1984 to the small but consistent volume of Argyle pink diamonds launched an icon: they became the Rolls Royce of the diamond market. They speak the language of exclusivity, desirability and collectability.

After running for almost 40 years, the annual Argyle Pink Diamonds Tender – which features a carefully curated catalogue of the finest gems from Argyle and an exclusive, invitation-only clientele – will end in 2021.

“I’ve had people from all over the world tell me: ‘the gems are beautiful, but it’s not about the diamonds – it’s about their origin, their honourable pedigree and their story,” Murray says.

Like all great stories, this one has an end. But no diamond story would be complete without a happily ever after. Ours is this: the rich, rare and romantic hues of our Argyle diamonds will live on in the hearts of everyone they touch, and as the lasting legacy of the East Kimberley, a wild, extraordinary corner of Australia.
