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.

The Great Indian Diamonds: A Closer Look At India’s Most Iconic Diamonds
De Beers Highlights India’s Historic Role In Shaping The Global Diamond Legacy Through A Curated Archive Of Iconic Gems
De Beers’ A Diamond is Forever marks Diamond Month with the release of “The Great Indian Diamond Archive”, a deep dive into 12 of the world’s legendary diamonds, all of which trace their origins back to India.
For centuries, diamonds have drawn attention for their brilliance and rarity, often associated with wealth, power, and prestige. What is less widely known, however, is that the story of diamonds began in India. Some of the most famous diamonds in the world, including the Koh-i-Noor, trace their origins back to the country.
At a time when much of the world was unfamiliar with diamonds, India had already established itself as a centre for diamond mining. The Golconda region was one of the earliest and most significant sources, producing several historic gems. Many of these diamonds were found along the Krishna River and eventually travelled across continents through trade, becoming part of royal treasuries.
Historical records suggest that diamond mining in India dates back to the 4th century BCE, making it one of the oldest known traditions in the world. Over time, these diamonds became associated with different rulers, empires, and geographies, each adding a new layer to their identity.

Diamonds such as the Koh-i-Noor, Hope Diamond, Regent, and Daria-i-Noor continue to be among the most talked about and valuable gems globally. Today, some are housed in museums, while others remain part of private or royal collections. Several of these diamonds have also been re-cut over time, changing both their appearance and identity.
Bringing these stories together, The Great Indian Diamond Index presents 12 of the most prominent diamonds associated with India. Developed as part of De Beers’ initiative, the index brings them into one place for the first time.
Rather than looking at these diamonds only as precious objects, the index traces their full journey—from their natural origins to their historical and cultural significance. It combines physical attributes with context to offer a more complete view of their legacy.
The list has been compiled using a structured research framework developed specifically as The Great Indian Diamond Index.
