Diamond industry operated amid uncertainty due to tariff negotiations between the U.S. and India
Diamond prices rose sharply at the beginning of April in response to announcements of new U.S. import tariffs, and then stabilized later in the month when the U.S. delayed the tariffs by 90 days.
The RapNet Diamond Index (RAPI™) for 1-carat goods edged up 0.7% during the month. The index for 0.30-carat diamonds continued to strengthen, rising 2.8% in April and 13.2% since the beginning of the year. The 0.50-carat RAPI increased 0.6%, while 3-carat stones saw a minor decline of 0.3%. VVS collection goods of 0.30 carats performed well due to increased Indian demand and a slight improvement in China.
The industry operated amid unprecedented uncertainty due to the continuing tariff negotiations between the U.S. and India, respectively the world’s largest diamond-consuming and -manufacturing countries. Trading slowed in centers outside the U.S. However, business within the U.S. was steady and prices rose, reflecting part of the expected tariff costs. The market is closely monitoring end-consumer reactions.
U.S. inventories are elevated, as American traders purchased goods before the tariffs’ anticipated start date, and global trading centers — especially Indian exporters — shipped popular goods to the U.S. Diamond imports to the U.S. are now experiencing a slowdown. Elongated fancy shapes saw strong demand in April, both internationally and in the U.S.
Diamond and jewelry retailers are finishing preparations for Mother’s Day on May 11, one of the key U.S. sales holidays. A survey by the National Retail Federation (NRF) projected that consumer spending on jewelry would be slightly lower than last year.
The rough market was quieter than in March, which was a particularly active period. Anglo American predicts that its customers will remain cautious about buying rough amid the ongoing macroeconomic uncertainty and the impact of U.S. tariffs. De Beers’ sales slid 44% year on year in the first quarter to $520 million as slow demand and a buildup of polished inventory led the midstream to restock more slowly.

Natural Diamond Council India Leads the Celebration of the First-Ever World Diamond Day
World Diamond Day celebrates the Personal Stories Behind Ntural Diamonds from Heirlooms to Modern Milestones
Jewellery has always held a deeply personal place in people’s hearts, and natural diamonds remain its most powerful expression. Every natural diamond carries within it a story of love, milestones, heritage and personal triumphs. On the first-ever World Diamond Day, these stories took centre stage, as people across the country came together to celebrate the meaning and emotion behind every diamond.
Launched by the Natural Diamond Council (NDC), World Diamond Day on April 8, 2026, was introduced as a global movement to recognise and celebrate the joy, passion, and community that natural diamonds inspire. Beyond their brilliance, diamonds represent memories, legacy, and the craftsmanship of a passionate industry that brings these stories to life.
As a champion of the natural diamond industry, NDC led this collective celebration, encouraging people from across the industry, from artisans and manufacturers to retailers and consumers, to share their authentic stories. The movement came alive on social media, with participants sharing personal moments using #WorldDiamondDay and #NaturalDiamonds, turning the day into a vibrant, global narrative.
In India, the celebration reflected a compelling blend of heritage and modern aspiration, as leading diamantaires and manufacturers spotlighted the journey of a diamond from its natural origin to a finished masterpiece. The reach of World Diamond Day was supported by the active participation of the Gem and Jewellery Export Promotion Council (GJEPC India), All India Gem and Jewellery Domestic Council (GJC) and the Bharat Diamond Bourse, who joined the movement to celebrate natural diamonds. This collective spirit was also embraced by leading industry partners, including Venus Jewel, SRK Exports, HK Exports, KP Sanghvi, Dharmanandan Diamonds, Finestar Jewellery and Diamonds, Shivam Jewels and A.S. Motiwala. Additionally, the movement was championed by prominent thought leaders such as Richa Goyal Sikri, Archana Thani, Nitya Arora and Arundhati De Sheth, all of whom played a significant role in bringing authentic stories and personal perspectives from across the industry to the global stage.
Richa Singh, Managing Director, Natural Diamond Council, said,
“World Diamond Day is a platform for people to share what their diamonds truly mean to them. At a time when consumers, especially younger audiences, are looking for more meaningful ways to celebrate, this initiative offers a reason to pause and honour those moments. Natural diamonds are the perfect custodians of our memories. This day is also a reminder of why we do what we do, to bring joy, emotion, and meaning into people’s lives.”
World Diamond Day has established itself as more than just a moment; it is a reminder of the joy behind every diamond, the passion of the industry, and the stories that connect us all. A natural diamond is not just a product, but a timeless heirloom, one that carries memories across generations and continues to shine with meaning.
Worn. Given. Passed down. Never forgotten.
Today, the story of natural diamonds belongs to everyone.
