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.
