De Beers Launches Biggest Campaign in 10 Years to Defend Natural Diamonds From Lab-Grown Rivals

Summary
October 2025 brought De Beers' "Desert Diamonds" campaign—its largest in a decade—alongside a jewelry-line rebrand and a new Paris flagship aimed at restoring the premium of mined stones.
Lab-grown diamonds, chemically identical to natural ones and sold at much lower prices, have won over younger buyers in the U.S. and East Asia, undermining De Beers' long-held pricing and cultural advantage.
The push revives a playbook De Beers used for decades: "A Diamond Is Forever" and salary benchmarks of two months in the U.S. and three in Japan helped turn engagement rings into a perceived tradition.
Japan shows both the power and limits of that model: diamond rings went from rare in the late 1960s to making Japan the No. 2 market by the late 1990s, but the three-month rule is now seen by many younger couples as dated.
Can De Beers’ new campaign restore the ‘magic’ of natural diamonds when lab-grown alternatives are identical and cheaper?
If the tradition of diamond engagement rings was invented, what will modern couples now choose to symbolize commitment?

Overview
De Beers launched the 'Desert Diamonds' campaign in 2025, marking its first major marketing push in over a decade and its largest investment in more than ten years. The campaign aimed to unite the diamond industry by celebrating the natural origins and unique warm tones of diamonds, reigniting consumer interest in natural stones. It brought together over 60 designers to create collections inspired by desert colors, especially for engagement and bridal jewelry. This industry-wide collaboration highlighted individuality and authenticity, positioning natural diamonds as rare and meaningful in a market increasingly challenged by lab-grown alternatives.
