Witness the Sparkle: A Timeless Diamond's Journey from Earth to Auction

The Debut of an Extraordinary Gem: 'The Jwaneng 28.88'

In a significant announcement this March, De Beers, in collaboration with the esteemed auction house Sotheby's, presented 'The Jwaneng 28.88' – an unparalleled natural diamond. This magnificent stone is scheduled to make its auction debut on April 23, 2026, as a highlight of Sotheby's prestigious Luxury Sales event in Hong Kong.

A Masterpiece from the Kalahari: Origin and Unrivaled Purity

Hailing from the legendary Jwaneng Mine in Botswana, a region whose name fittingly translates to 'a place of small stones' in Setswana, this diamond possesses an internal flawlessness and D-color grading. Weighing an impressive 28.88 carats, 'The Jwaneng 28.88' is valued with an estimated price between 2.2 and 2.8 million USD, truly embodying a rare combination of age and impeccable origin.

Celebrating an Enduring Legacy: 'A Diamond Is Forever'

The unveiling of this exquisite gem perfectly aligns with the release of De Beers' monumental publication, 'A Diamond Is Forever – The Making of a Cultural Icon,' produced by Assouline. This literary work delves into the history and profound influence of the slogan 'A Diamond Is Forever,' originally conceived in 1947 by American copywriter Mary Frances Gerety. As De Beers prepares to commemorate a century of narrative excellence in 2026, this moment paves the way for the 80th anniversary of this iconic phrase in 2027, solidifying its revered position in the collective consciousness across generations.
