Boodles takes Argyle's brand, once over 90% of pink supply
Rio Tinto put no price on the transfer. Boodles also acquired the last remaining Argyle pink-diamond inventory, a suite of trademarks, the website and the digital marketing assets; the mine stopped producing on 3 November 2020.

What changed
Ownership moved. Rio Tinto transferred the Argyle Pink Diamonds brand to Boodles on 1 October 2026. Boodles acquired the last remaining Argyle pink-diamond inventory and a suite of trademarks, plus the website and digital marketing assets. No price was published.
What it means
- If you trade Argyle pinks: The last certified inventory now sits with one British retailer.
- If you value a pink: No consideration was published, so this sets no price benchmark.
- What this is not: A reopening. Production ended on 3 November 2020 and the mine stays closed.

No price in the release.
Nothing was disclosed. Rio Tinto's release names no consideration for the brand, the trademarks or the inventory. It gives no carat weight and no stone count for what transferred.
The inventory is finite. Boodles acquired the last remaining Argyle pink-diamond inventory. Production at the mine ended on 3 November 2020, so no further Argyle rough exists to replace it.

Notes on this table
Every row is Rio Tinto's own wording in its release of 1 October 2026, read as raw bytes and grepped before printing. The Price row is an absence in the document, not a redaction inferred here: the release names no consideration, no earn-out, no inventory carat weight and no stone count. Rapaport's report of the same transfer carries no figure either. Carat Capital computes nothing in this table, because there is no number in the document to divide.
The buyer is a retailer.
Not a miner. Boodles is a family-owned British jeweller. Patrick Coppens, Rio Tinto Diamonds general manager of sales and marketing, calls it “a family-owned company with 228 years' experience”.
Stewardship was the test. Coppens names an owner who understands the brand's history as the priority in the choice. Boodles managing director Jody Wainwright puts the stones' role in the firm's designs at more than 40 years.
What Rio Tinto keeps.
The site stays. Rio Tinto says it remains committed to closing and rehabilitating the Argyle site, recognising the Traditional Owners' connection to Country. The release attaches no date and no budget to that work.
The unit had shrunk. Carat Capital put Rio Tinto's diamond unit revenue at $118 million on 29 July 2026 as Diavik wound down. This transfer removes the last Argyle marketing asset from that unit.
What to watch
- Rio Tinto's next quarterly operations reviewWhether the diamond segment still carries an Argyle line now the brand has gone. Rio Tinto's own calendar page returned no dated entry when read on 2 October 2026.
- Boodles' next collection announcementWhether Boodles prices Argyle goods publicly or holds them as private-client stock.
- The Argyle closure planWhether a rehabilitation date or budget is published now the brand sits outside the group.
The story so far

What would change this call
A price appearing later. The whole reading here rests on an absence: Rio Tinto published no consideration, so nothing in this transfer prices an Argyle pink. If a figure surfaces in Rio Tinto's accounts or in a Boodles filing, the deal becomes a datum the trade can use to value the remaining certified inventory, and the desk's view that this sets no benchmark fails. The second reading that would change the call is a published carat weight for the inventory: the brand without the stones is a trademark, and the brand with a large certified parcel is a trading position.
Why an Argyle brand is separable from a mine
Argyle Pink Diamonds was a marketing programme as much as a geological fact. Rio Tinto ran an annual invitation-only tender of the mine's best pink, red and violet stones, certified each one against the Argyle name, and built a register of buyers around that certification. The register, the trademarks, the lot-numbering convention and the certificates are assets that survive the orebody, which is why they could be sold six years after production stopped. What a buyer acquires is the right to certify and market under the name, plus whatever certified stones remain in the vault. What it cannot acquire is new supply: the mine's pit is being closed and rehabilitated, and no other deposit produces the same colour at the same scale, which is the sense in which Rio Tinto's own release calls Argyle the world's first and only source of pink diamonds producing more than 90 per cent of world supply. The practical consequence is that the brand's value is now a function of a fixed, shrinking inventory and of how slowly its owner chooses to release it.
Method
Two documents were fetched with a browser identity and saved as raw bytes before any figure was written: Rio Tinto's own media release, 200, 152,664 bytes, and Rapaport News' report of the same transfer, 200, 461,824 bytes, JSON-LD datePublished 2026-10-01T10:42:04+00:00. Exact-string grep counts in the saved Rio Tinto file: '228 years' one hit, '90 per cent' one hit, '3 November 2020' one hit, '1 October 2026' two hits, '40 years' one hit. A search of the same file for a dollar, pound or consideration figure returned only navigation strings such as share-price links, no transaction figure; that absence is why the Price cell reads None rather than a number. The Coppens quotation is seven words and was read in the release's own body. An SEC exhibit surfaced by search under the file name ex15d24mr_argylepink was fetched with an identifying user agent, 200, 23,813 bytes, and opened: it is an unrelated Argyle Pink Diamonds and West Australian Ballet announcement, not this transfer, and it is therefore not cited. Separately, one Carat Capital beat desk filed this item with a $150 million price attached. The exact string '$150 million' returns zero hits in the Rio Tinto release and three in Pandora's Vietnam report published the same morning, which is where that figure belongs; it is recorded here because the figure never reached print. The archive was checked by opening every hit rather than counting: Boodles returns zero articles; Argyle returns three, all opened, dated 21 July 2026 (Diavik's final 33,000 carats), 26 July 2026 (Diavik's last ore) and 29 July 2026 (Rio's diamond unit at $118 million). The nearest is the last of those: same entity, Rio Tinto, but its period is the first half of 2026's unit revenue, where this item's period is a brand transfer completed on 1 October 2026. Different period and different event, so the verdict is ADVANCED, not a repeat, and the brand sale itself has never been covered here.
