On July 30, 2024, the global diamond industry was blindsided when U.S. President Donald Trump invoked Section 301 of the Trade Act to impose a 25% tariff on all Indian diamond imports, effective midnight August 1.

This seismic policy shift struck at the heart of an industry where India polishes 9 out of 10 diamonds traded globally. Within hours, trading floors from Mumbai to Antwerp descended into chaos as:

Spot prices for 0.30-1.00ct G-H/VS-SI rounds surged 8-12%

U.S. retailers canceled $120M+ in pending orders

De Beers’ stock plummeted 7.3% in after-hours trading The Financial Times called it "the most disruptive trade action since the 2008 financial crisis" for luxury goods.
