US Jewellery Industry faces $117 Billion threat amid proposed diamond tariffs
The World Diamond Council (WDC), representing the global natural diamond value chain, has raised concerns over proposed U.S. tariffs that could place the $117 billion American jewellery industry at significant risk. In a formal appeal, the WDC urged the U.S. Administration to exempt natural diamonds (HS Codes 7102.10 and 7102.31) from the ongoing tariff review and include them in Annex II, citing their critical role in the nation’s economic and manufacturing sectors.
Natural diamonds, though not produced in the U.S., are essential to the health of the domestic jewellery market — a sector supporting over 200,000 American jobs and generating over $91.5 billion in annual sales. The combined impact of jewellery manufacturing and exports adds another $25.5 billion to the economy each year.
The WDC warns that tariffs on natural diamonds would effectively act as a consumption tax, raising prices on popular items like engagement rings and anniversary jewellery, placing additional financial strain on American families. Retailers are already experiencing inventory concerns, with inflationary pressures beginning to impact consumer prices.

“A tariff would destabilize the supply chain, weaken U.S. manufacturing competitiveness, and increase costs for consumers,” said Feriel Zerouki, President of the World Diamond Council. “We support the U.S. Government’s goal of fair trade, but urge an exemption for natural diamonds to protect jobs, competitiveness, and consumer access.”
The United States is the world’s largest consumer of natural diamond jewellery. The WDC emphasized that continued access to these goods is vital to preserving the innovation, craftsmanship, and entrepreneurship that define the American jewellery industry.
WDC members are actively engaging with U.S. officials, calling for a collaborative resolution that supports fair trade without undermining one of America’s most valuable consumer markets.
