The Diamond Dudes: De Beers Cuts, Tightening Supply and the Battle for the Consumer

In Episode 4 of The Diamond Dudes, Rob Bates, Edahn Golan, and Avi Krawitz unpack major developments in the diamond industry, from De Beers' latest sight price adjustments and significant cuts to its Sightholder list to what those changes reveal about the company's long-term strategy.

The conversation explores the implications of global diamond production falling below 100 million carats for the first time, the evolving competitive dynamics between natural and lab-grown diamonds, shifting retail economics, and how jewelers can position both products in an increasingly polarized market.

Along the way, the Dudes debate the future of the De Beers brand, examine changing consumer buying behavior, discuss why old mine-cut diamonds are suddenly surging in popularity, and look ahead to the trends and challenges likely to define the diamond industry for the rest of the year.
