U.S. to Enforce New Diamond Import Rules Requiring Mining Country Disclosure
Starting in April 2025, U.S. importers must declare diamond mining origins to prevent Russian diamonds from entering the market.
In a move to strengthen sanctions on Russian goods, the U.S. Customs and Border Protection (CBP) will introduce stricter regulations for diamond imports beginning in April 2025. Under the new rules, importers will be required to provide additional data on diamond shipments, including the declaration of the Country of Mining. This will help ensure compliance with Executive Order 14114 and prevent Russian-mined diamonds from being imported through third-party countries.
A key part of the update is the introduction of a self-certification requirement. Importers will need to verify that their diamonds do not originate from Russia, submitting this confirmation through the Document Image System (DIS) using the new CBP167 code. This replaces the previous generic label, streamlining the process while tightening scrutiny of diamond sources.
The decision is part of broader international efforts to stop Russian diamonds from entering global markets, especially after the country’s invasion of Ukraine. With these changes, the U.S. government aims to close loopholes that have allowed Russian diamonds to be processed and sold under other country labels.
CBP has been working closely with industry stakeholders and has updated its ACE Cargo Release Implementation Guide to assist with the transition. Importers are encouraged to review the new guidelines and join biweekly trade support calls to stay informed and address any questions.
The new rules will come into effect in April 2025, with the mandatory self-certification document requirement beginning in January 2025. Importers are advised to prepare in advance to avoid potential delays or enforcement actions.

Natural Diamond Council: Average Engagement Ring Price Surpasses $7,000 in 2025
Round Cuts Dominate Sales as Larger Carat Stones, Gen Z Buyers and Self-Purchases Drive US Natural Diamond Demand
The average price of an engagement ring in the US rose 9% in 2025 to $7,364, according to the latest trend report released by the Natural Diamond Council (NDC).
Round diamonds continued to dominate the engagement-ring category, accounting for 62% of units sold, followed by oval shapes at 14%. The average center stone size stood at 1.16 carats, with SI1 clarity emerging as the most common grade. Overall, diamond engagement rings — including loose stones and semi-mounts — represented 38% of natural-diamond jewellery sales by volume during the year.
The report, based on data compiled by Tenoris from more than 4 million jewellery transactions across 2,500 US specialty retailers, highlighted evolving consumer preferences in cut, carat weight and design. Celebrity engagement trends also influenced demand, with styles such as marquise and elongated cushion cuts gaining visibility.
Beyond engagement rings, tennis bracelets, wedding bands and pendants recorded the strongest growth in units sold. Bracelets led in pricing, rising 15% year-on-year to an average of $3,600. The average price of rings increased 11% to $2,537, while necklaces climbed 40% to $2,366. Earrings rose 17% to $2,068, and pendants advanced 17% to $1,126.
In terms of stone size, sales of 1.50–1.59 carat diamonds grew 15%, and 2–2.24 carat stones increased 10%. Although the 1–1.04 carat category maintained the largest market share, it experienced a 7% decline in sales volume.
Looking ahead, the NDC projects that Gen Z consumers will remain the fastest-growing segment of diamond buyers in 2026, with younger shoppers increasingly driving self-purchase trends. The council also noted growing momentum in men’s diamond jewellery, supported by rising visibility and shifting cultural attitudes toward diamond ownership.
