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.

Pandora Adds Carbon Footprint Labelling For LGDs
New Level Of Transparency Empowers Consumers To Compare Climate Impact Of Their Diamond Jewellery
For decades, diamonds have been graded by the traditional 4Cs: Cut, Colour, Clarity and Carat. Now Pandora is adding the 5th C, declaring the carbon footprint of every Pandora Lab-Grown Diamond as part of the product information on pandora.net alongside the traditional four grading criteria.
The carbon footprint covers all emissions from the diamond crafting process: from producing the raw materials used to grow the diamond all the way until it is cut and polished, ready to leave the diamond facility.
As an example, a one carat Pandora Lab-Grown Diamond has 12.58 kg of CO2e emissions. This is around 90% lower than a mined diamond of the same size.
By adding carbon footprint to the diamond conversation, Pandora gives customers an extra point of comparison and essential insight into the climate impact of their desired diamond jewellery.
CARBON FOOTPRINT COMPARABLE TO A PAIR OF JEANS
Lab-grown diamonds are chemically, optically, thermally and physically identical to mined diamonds.
Pandora stopped using mined diamonds in 2021 and is now only using lab-grown diamonds made with 100% renewable electricity and set in jewellery crafted from 100% recycled silver and gold.This significantly reduces the carbon footprint of the Pandora Lab-Grown Diamonds collection. For example, a 14k gold Pandora Infinite ring with a 1 carat lab-grown diamond has a comparable carbon footprint to a pair of jeans.
PANDORA TO SHARE FINDINGS
The carbon footprints of Pandora’s lab-grown diamonds have been calculated by external life-cycle assessment experts and published in a study verified by auditing firm EY. The study uses best practice methodology and is available on pandoragroup.com.
Adding a 5th C is a response to increasing consumer expectations to sustainability, and Pandora will share its methodology and findings with other jewellery makers to inspire greater transparency across the sector.
Pandora Lab-Grown Diamonds are currently available in the US, UK, Canada, Australia, New Zealand and Denmark with more countries to be added soon.
