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.

Zen Diamond Unveils the Soirée Collection: Where Modern Gold Meets Italian Artistry

Zen Diamond, the internationally acclaimed fine jewellery brand, introduces The Soirée Collection — a bold and elegant line of contemporary gold jewellery that blends modern design with the finesse of Italian craftsmanship. Each piece in the collection is thoughtfully designed to elevate evening wear, offering a seamless balance of sophistication and standout style.
Crafted in polished gold and accentuated with exquisite detailing, The Soirée Collection brings together sculptural forms, refined silhouettes, and signature touches that celebrate quiet luxury. From intimate dinners to formal galas, the pieces are designed to make a lasting impression.
A standout piece is the coiled gold bracelet, gracefully encircling the wrist with fluid form and diamond-accented ends, shaped in marquise and round motifs. Inside, Zen’s hidden signature diamond adds a discreet mark of excellence.






The wind chime-inspired necklace features a cascade of layered gold bars anchored by a diamond-set central bar and a sapphire clasp, marrying movement and colour in harmonious rhythm.
Another highlight, a sculptural necklace with a twin-arc design, is crafted in warm gold and finished with a diamond-studded bar at the center, embodying strength and elegance.
Sculptural rings in the collection embrace open-ended forms — one featuring a diamond-set square and arrow motif for a bold contrast, while another showcases closely set pavé diamonds at either end, creating a radiant and modern silhouette.
Completing the collection are refined earrings shaped in an elongated marquise form, enhanced by a rhythmic pattern of alternating diamonds along the inner curve. An iris-inspired stud adds a poetic finish, reflecting Zen Diamond’s commitment to detail and artistry.

AfDB approves $304 million loan to Botswana

The African Development Bank (AfDB) has approved a $304 million loan to support Botswana’s efforts to stabilise its public finances and implement key economic and governance reforms amid falling diamond revenues.
It marks a critical intervention in the country’s ongoing struggle with fiscal instability, primarily driven by a sharp decline in diamond revenues. This analysis examines the context, intent, and expected impact of the loan, as well as the broader economic challenges facing Botswana.
The loan aims to help Botswana navigate a widening fiscal deficit—expected to hit 6.7% of GDP this year—after the economy shrank by 1.7% in 2024, largely due to subdued global demand for diamonds, which account for around 80% of the country’s exports.
The $304 million loan is structured as a one-year general budget support operation for the 2025/26 fiscal year, under the Governance and Economic Resilience Support Programme (GERSP). The program is designed to address two main objectives:
Strengthening fiscal sustainability and transparency: Measures include boosting domestic revenue collection, curbing illicit financial flows, and enhancing the efficiency and accountability of public spending.
Stimulating inclusive economic growth: The program supports micro, small, and medium enterprises (MSMEs), with a particular focus on businesses owned by women and youth, to foster job creation and reduce inequality.

Surat diamond manufacturers implement summer shutdowns on lower demand

Diamond manufacturers in Surat, India’s diamond polishing hub, have begun implementing summer shutdowns for the first time in years as demand for natural stones remains persistently weak and the threat of steep U.S. tariffs looms over the industry.
Traditionally, factories in Surat—home to nearly 4,000 diamond units—take their main annual break during Diwali, remaining operational through the summer months. However, the ongoing downturn has prompted many units to extend Diwali closures and introduce unpaid summer breaks, a move not seen in previous years.
Around 10% of Surat’s diamond factories have declared a summer holiday of at least 15 days, with some major units planning to stay shut until June 6, according to industry sources and local media reports. The closures have triggered an exodus of thousands of migrant workers, many of whom are returning to their hometowns in Saurashtra and North Gujarat as operations wind down.
