Jwaneng 28.88 Diamond Sale Marks Start of De Beers, Sotheby’s Collaboration
Collaboration Centers on Joint Marketing and Storytelling, Both Companies Co-create a Branded Narrative – “Earth To Art”
The sale of the Jwaneng 28.88 diamond later this month marks the start of a collaboration between De Beers and Sotheby’s.
This isn’t a simple transaction; it’s a narrative takeover. Under the banner “Earth to Art,” the two giants are co-creating a branded experience that tracks the journey of a stone from the deep-time pressure of the Botswana crust to the white-glove stage of the auction house.
The face of this revolution is the Jwaneng 28.88. A flawless, D-color, unmounted miracle, this diamond was carved from a massive 114.83-carat rough pulled from the legendary Jwaneng mine—the “Prince of Mines.”
It doesn’t just sparkle; it demands attention. This isn’t just carbon—it’s a curated relic of the earth’s core, reimagined for the modern collector.
The Sale Details
The Jwaneng 28.88 will headline the Magnificent Jewels & Jadeite sale in Hong Kong. It is accompanied by a curated selection of other Jwaneng-sourced treasures, including a solitaire ring and a pair of diamond earrings that redefine “standard” brilliance.
- Auction Date: 23 April.Location: Sotheby’s Hong Kong
- Estimate: HKD 17M – HKD 22M ($2.2M – $2.8M USD)
While the specific legal ink of the deal remains under wraps, the intent is clear: De Beers and Sotheby’s are no longer just seller and platform. They are storytellers. By merging De Beers’ unrivaled access to the source with Sotheby’s cultural authority, “Earth to Art” ensures that a diamond is never just a stone again. It is a legacy you can hold.

DE BEERS GROUP Introduces Desert Diamonds Icons
Supported by the Diamond Industry’s Largest Marketing Budget In 15 Years, Desert Diamonds Icons Will Launch Ahead Of The End Of Year Holiday Season and Build On The Desert Diamonds Campaign’s Success In Driving Natural Diamond Desire
At the annual JCK Las Vegas Show – the largest jewellery event in the global calendar – De Beers Group today set out its view on the way forward for the natural diamond sector, calling on the trade to work together to capitalise on the early success of the Desert diamonds ‘beacon’ campaign with the introduction of Desert diamonds Icons.
The Desert diamonds beacon campaign launched in late 2025 and has already succeeded in shaping consumer demand for both natural diamonds in general and coloured diamonds in particular, with natural diamond sales at US independents increasing 4% in Q4 2025 and 9% in Q1 2026, while those in the K to Z colour range have seen even stronger growth, up 15% in Q4 2025 and 19% in Q1 2026.
Following the launch of Desert diamonds Bridal earlier this year, Desert diamonds Icons will focus on bringing a sense of newness and individuality to four iconic jewellery design classics – stud earrings, the eternity band, the tennis bracelet and the halo pendant – which between them comprise 70% of diamond jewellery acquisitions. Launching in September, the campaign will include training and marketing support for all retailers.
During a keynote presentation, De Beers Group executives stated that while demand has performed well for larger natural diamonds and this has supported stable retail sales value for natural diamond jewellery, it is critical for industry participants to work together on the campaign to drive demand across the natural diamond category as a whole.
With the campaign benefitting from the diamond industry’s biggest natural diamond marketing budget in 15 years, Desert diamonds is expected to deliver enhanced retail impact in 2026, based on a range of positive data points from its initial run. Growth in natural diamond desirability, online searches for natural diamonds, and increased coloured natural diamond sales across independent jewellers all highlight that the momentum behind the campaign is building. Noting that the 2026 campaign run will also benefit from a geo-targeting approach that directs consumers to specific retailers carrying Desert diamonds, De Beers executives encouraged the entire trade to support the fast-growing trend by stocking Desert diamonds Icons products and by signing up to Promoboxx to access marketing materials and participate in geo-targeting.

The presentation also included a summary of key consumer and industry insights published today in The Diamond Report, highlighting how commercial dynamics are evolving at pace for US jewellery retailers as the synthetic lab-grown diamond sector matures while consumer interest in natural diamonds grows.
Speaking at the presentation, Al Cook, CEO of De Beers Group, said:

“Consumer desire for natural diamonds is strong – but we need to work together as an industry in support of Desert diamonds to unlock the full value of the opportunity. The results from the campaign’s initial run demonstrate how it is already stimulating demand, and with Desert diamonds Icons we are doubling down at a critical moment.”
“The jewellery retail landscape is evolving at pace. With the sustained falls in price of synthetic lab-grown diamonds, and large falls in demand for larger synthetic lab-grown diamonds, there may be challenges ahead for retailers who focus on synthetic lab-grown diamonds.”
“However, with challenge comes opportunity, and the growing success of the Desert diamonds campaign is evident. As we head into the campaign’s second year, with the industry supported by the largest category marketing budget in 15 years, the natural way forward is clear to see.”
De Beers Group also reported in its presentation how collaboration continues deliver progress in other areas, with GIA’s purchase of an equity share in Tracr supporting the platform’s path to independence and providing the potential for it to scale faster across the sector.
Meanwhile, the Natural Diamond Council has put in place a compelling new strategy on the back of its growing budget, as more diamond producing countries and trade bodies have provided funding, and will introduce a new natural diamond trust mark to support consumer confidence through visible differentiation between natural diamonds and synthetic lab-grown diamonds.
