Tariffs Mark the Latest Blow for Already Struggling Diamond Sector
(CNBC, May 27, 2025)
The imposition of a 10% import duty on polished diamonds entering the U.S. — the largest global market — adds pressure to an already struggling diamond sector. The luxury market faces challenges from economic downturns and a post-pandemic demand slump, especially in China. Lab-grown diamonds (LGD), chemically identical but sold at 80% discounts, are rapidly gaining market share, with over half of U.S. engagement rings featuring LGDs last year. Pandora, the largest jewelry brand by volume, ceased selling mined diamonds in 2021, signaling a major industry shift. Despite plunging prices for natural diamonds (down nearly 60% since March 2022), some analysts believe the market may soon stabilize as consumers begin to distinguish between natural and lab-grown stones. De Beers is focusing on natural diamonds, closing its LGD brand Lightbox amid these challenges.
Industry Focuses on Las Vegas Shows Amid Uncertainty
(Rapaport, May 29, 2025, based on April data)
The diamond industry is focused on the upcoming Las Vegas shows while cautiously awaiting market developments. A U.S. court ruled that former President Trump lacked authority to impose tariffs, adding to market uncertainty. Indian trade remains slow due to weak overseas and domestic demand for polished diamonds. Long fancy shapes such as Oval, Marquise, and Emerald cuts outperform rounds, with high-quality stones scarce and commanding premiums. De Beers forecasts Indian diamond demand to double over the next five years. Botswana’s president advocates for local polishing of all rough diamonds. Swiss watch exports surged 18% year-over-year in April amid pre-tariff shipment spikes to the U.S. Colored stones dominated a $48 million Christie’s auction in Hong Kong. Market activity is steady but cautious, with dealers preparing for JCK Las Vegas and hoping for tariff solutions.
