British fine jeweller Boodles has acquired the Argyle Pink Diamonds brand and Rio Tinto’s final remaining inventory of the rare Australian gemstones, marking a significant new chapter for one of the world’s most recognisable names in coloured diamonds.
Completed on 1 October 2026, the acquisition places the future of Argyle Pink Diamonds in the hands of a family-owned British jewellery house with more than two centuries of heritage. The agreement includes the brand’s associated trademarks and digital assets, alongside the remaining pink diamonds previously held by mining group Rio Tinto.
The transaction comes almost six years after production ended at Australia’s Argyle diamond mine, once responsible for more than 90% of the world’s pink diamond supply. With no new stones emerging from the historic mine, Boodles now plans to bring its acquired diamonds to market gradually, including through a new high-jewellery collection scheduled for 2027.

Boodles Takes Ownership of an Extraordinary Diamond Legacy
The acquisition represents a significant milestone for Boodles, bringing the Argyle Pink Diamonds brand under the ownership of one of Britain’s oldest family-run jewellery houses. Founded in Liverpool in 1798, Boodles has developed an international reputation for fine jewellery that combines exceptional gemstones, distinctive design and traditional craftsmanship.
Under the agreement with Rio Tinto, Boodles has acquired the Argyle Pink Diamonds name, a collection of associated trademarks and digital assets, together with the mining company’s final remaining inventory of Argyle pink diamonds. The transfer officially completed on 1 October 2026, placing responsibility for the brand’s future identity and development with the British jeweller.
The financial terms of the transaction remain undisclosed, as does the number and total carat weight of diamonds included in the agreement. Importantly, the acquisition concerns Rio Tinto’s remaining inventory rather than every Argyle pink diamond already held by collectors, jewellers and private owners around the world.
For Boodles, the acquisition represents more than an opportunity to secure an exceptional collection of gemstones. It also provides the opportunity to guide the future of a brand whose reputation rests on provenance, geological rarity and decades of international recognition.
Patrick Coppens, General Manager of Sales and Marketing at Rio Tinto Diamonds, emphasised the importance of finding an appropriate custodian for the historic diamond brand.
“Our priority has been to ensure that the Argyle Pink Diamonds brand remains with an owner who understands its history…”

The statement reflects the significance of the transaction beyond the transfer of gemstones and trademarks. With the Argyle mine permanently closed, preserving the brand’s identity and the provenance of its remaining diamonds will be central to its future under Boodles.
Why Argyle Pink Diamonds Are So Rare
Located in the remote East Kimberley region of Western Australia, the Argyle Diamond Mine became one of the world’s most important sources of naturally coloured diamonds. During its operating life, the mine produced more than 90% of the global supply of pink diamonds, establishing an extraordinary reputation among jewellery houses, collectors and gemstone specialists.
Despite the scale of its overall diamond production, pink diamonds represented only a tiny proportion of the mine’s output. Their distinctive colours, ranging from delicate pink and purplish pink to deeper, more saturated shades, made them particularly desirable within the high-jewellery market.
Argyle also developed its own colour grading system to distinguish the subtle variations between individual stones. Combined with documentation and authentication processes, this helped establish a recognisable identity for diamonds originating from the Australian mine.
Production officially ended on 3 November 2020, closing a remarkable chapter in Australian mining history. Although natural pink diamonds can originate from other deposits, the Argyle source is now permanently finite, giving its remaining stones a particular significance within the world of rare gemstones.
A Relationship That Began in 1998
Boodles’ connection with Argyle pink diamonds stretches back considerably further than the latest acquisition. The Wainwright family purchased its first Argyle pink diamond in 1998, beginning a relationship that would influence the jeweller’s collections and even aspects of its visual identity.
According to the official Argyle Pink Diamonds website, it was an Argyle stone that inspired Boodles President Nicholas Wainwright to introduce the distinctive shade of pink that has since become closely associated with the jewellery house.
Over the following decades, the gemstones became an important part of Boodles’ creative expression, appearing in collections including Raindance, Play of Light and Be Boodles. Their delicate colouring and individuality provided a natural complement to the brand’s contemporary approach to fine jewellery design.
That longstanding relationship helps explain the significance of the acquisition. Rather than introducing a new gemstone category to its portfolio, Boodles is taking responsibility for a diamond brand with which it already shares a substantial history.
The Future of Argyle Pink Diamonds
With the mine closed and Rio Tinto’s final remaining inventory now transferred, attention turns to how Boodles will introduce the acquired diamonds into future collections.
The jeweller has indicated that it intends to release the stones gradually over approximately ten years, rather than bringing the entire inventory to market immediately. This approach would allow the gemstones to feature in carefully developed jewellery designs across several collections, with the exact timing dependent on Boodles’ creative plans.
The company has already confirmed that Argyle pink diamonds will take centre stage in a new high-jewellery collection in 2027. While detailed designs have yet to be revealed, the collection will bring together British craftsmanship and the distinctive Australian provenance of the stones.
Boodles Managing Director Jody Wainwright described the importance of the new responsibility:
“We are incredibly proud and honoured to be entrusted with the future of the Argyle Pink Diamonds™ brand.”

For collectors and admirers of fine jewellery, the forthcoming collection will offer an opportunity to see how Boodles interprets the Argyle legacy through its own design language. The acquisition also gives the jeweller greater influence over how the brand’s story is presented to future generations.
The Importance of Provenance in High Jewellery
The Argyle name carries a significance that extends beyond colour and rarity. Its association with a specific Australian mine gives the diamonds a distinct geographical identity, supported by grading, documentation and authentication systems developed during the mine’s operating life.
Within the high-jewellery market, such provenance can play an important role in distinguishing individual gemstones. Understanding a diamond’s origin, characteristics and documented history provides additional context for a purchase, particularly when dealing with rare coloured stones.
The transition to Boodles also raises questions about the future management of the Argyle Pink Diamonds identity and its established relationships with other jewellery businesses. Existing brand licensing arrangements continue under their previous terms until their scheduled expiry, while Boodles considers its longer-term approach.
Preserving the credibility of the Argyle name will therefore be an important element of the jeweller’s new responsibilities. The company must balance the creative possibilities offered by the remaining stones with the heritage and established reputation that made them desirable in the first place.
A Significant Moment for British Fine Jewellery
The acquisition arrives at an important time for Boodles, following the opening of its new townhouse flagship at 23 Old Bond Street in London. The expanded Mayfair destination brings together high jewellery, private hospitality and British craftsmanship, creating a prominent setting in which to showcase some of the jeweller’s most exceptional creations.
The townhouse already celebrates the company’s longstanding connection with rare pink diamonds through its Argyle Lounge and the 23 Old Bond Street high-jewellery suite. The acquisition provides a further dimension to that relationship, allowing Boodles to connect its contemporary collections with the history of the Argyle brand.
For a business that began in Liverpool more than 228 years ago, taking ownership of such a significant gemstone legacy represents a notable development. It also reinforces the role that established family-owned jewellery houses continue to play in shaping the future of luxury craftsmanship.
The Love Lux Life View
Few gemstones possess quite the same combination of distinctive colour, documented provenance and historical significance as Argyle pink diamonds. Their appeal extends beyond their appearance, reflecting the extraordinary circumstances of their formation and the finite nature of a source that can no longer produce new stones.
For Boodles, acquiring the Argyle Pink Diamonds brand represents an opportunity to preserve that heritage while introducing the gemstones to a new generation of jewellery collectors. The company’s longstanding relationship with Argyle provides a compelling foundation, particularly as the remaining inventory begins to appear in future designs.
The forthcoming 2027 high-jewellery collection will be an important indication of how Boodles intends to approach its new role. More than simply presenting another collection of rare diamonds, it offers the British jeweller an opportunity to shape the next chapter of a remarkable Australian legacy.
