After a 9% sales jump at US independents, De Beers expands its Desert Diamonds campaign with an Icons line covering 70% of acquisitions. The push intensifies the industry's fight against lab-grown stones.
De Beers used the JCK Las Vegas show to report that its Desert Diamonds campaign is working. Natural diamond sales at US independent jewellers rose 9% in the first quarter of 2026, following a 4% gain in the fourth quarter of 2025. Coloured diamonds in the K to Z range did even better: up 19% in Q1. Now the company is adding a new product line called Desert Diamonds Icons, launching in September, that targets the four jewellery categories accounting for 70% of all diamond acquisitions: stud earrings, eternity bands, tennis bracelets and halo pendants.
The campaign first hit the market in late 2025, focused on coloured natural diamonds. De Beers said online searches for natural diamonds have risen, and the marketing budget is the largest the industry has seen in 15 years. The new Icons line will come with training and marketing support for retailers, plus geo-targeted digital ads that push shoppers toward specific stores carrying the branded inventory.
The critical moment Cook refers to is the collapse in prices for synthetic lab-grown diamonds. Demand for larger lab-grown stones has fallen sharply, and Cook warned that retailers who focus on synthetics face challenges. The broader Desert Diamonds push is De Beers' answer: a coordinated industry-wide marketing effort to reassert the natural diamond's premium positioning.
De Beers also noted that GIA recently took an equity stake in Tracr, the diamond traceability platform, which could help it scale faster. The Natural Diamond Council is rolling out a new trust mark designed to help consumers distinguish natural diamonds from lab-grown stones.
The Desert Diamonds Icons launch in September. The next data point to watch will be Q3 sales at independent US jewellers – those numbers will show whether the campaign's initial lift can hold.
