The Reality of The Diamond Industry; All You Need To Know
Over the past 18 months, we have significantly enhanced this report, incorporating new data and insights that reflect the evolving landscape of the diamond industry

The Natural Diamond Council recently released the second edition of the Diamond Facts Report, continuing its mission to dispel myths and protect consumers from misinformation about the diamond industry. This report serves as a comprehensive guide, offering accurate and transparent information to help consumers make informed choices, backed by updated data. By addressing key questions and providing insights, the report reinforces NDC’s commitment to educating and empowering buyers while supporting the integrity of the natural diamond industry.
Highlights from the NEW Diamond Facts Report:
● Positive impact of natural diamonds with new examples from producing countries
The natural diamond industry supports 10 million livelihoods globally. NDC member companies contribute to communities through local employment, sourcing, and investments in health, education, and infrastructure, aiming to share the mine’s success and prepare communities for post-closure stability.
● Environmental stewardship
The majority of our manufacturing partners in India are adopting renewable energy and implementing sustainable practices throughout their operations. Efforts include using solar and wind energy, achieving Net Zero goals, reforestation projects, and investments in biodiversity and water management to create lasting environmental benefits.
● Diamond verification
The Natural Diamond Council started the ASSURE Program in 2019 to test how well Diamond Verification Instruments work. The results, including details on accuracy, false positive rates, and referral rates, are available in the ASSURE Directory.
● Updated information on pricing and production
Laboratory-grown diamond prices have dropped significantly, with a 1.5-carat stone declining 83% since 2015. Natural diamonds, with prices influenced by rarity, have shown a long-term annual growth rate of 3% since 1970 and a 2% yearly increase in rough diamond prices since 2007, despite market fluctuations
● Disclosure and diamond terminology
Legal definitions and advertising guidelines are in place to protect consumers and ensure they can clearly distinguish between natural and laboratory-grown diamonds.
● Traceability and responsible sourcing of natural diamonds
The diamond industry is heavily regulated under the Kimberley Process, established by the United Nations and the World Trade Organization, ensuring all rough diamond trade is conflict-free. A strong system of checks and balances, including audits of major industry players, upholds the importance of ethical sourcing.
● Responsible mine closure
It takes, on an average, 10 years to open a mine. Having a closure plan is a prerequisite to opening a mine, in addition to social and environmental impact assessments which are audited, approved, and monitored by governments and local communities.
David Kellie, CEO of Natural Diamond Council said, “Natural diamonds are Earth’s real treasures, exceptionally rare, responsibly sourced in a way that supports livelihoods and contributes to conservation efforts around the world. This new edition of Diamond Facts sets out to address the most common myths about the diamond industry, covering everything from synthetic diamonds to natural stones mined from deep underground.
We also encourage you to explore our other reports in this series, including Diamonds of Canada. We will regularly be issuing reports in partnership with leading experts, data organisations and diamond industry representatives.”
Richa Singh, Managing Director, NDC India and Middle East said, “Diamonds have long been symbols of enduring value and connection, carrying a legacy that extends beyond their inherent beauty. This latest edition of Diamond Facts reflects our commitment to providing transparent, data-driven insights and highlighting the positive social and economic contributions of the diamond industry in producing countries. Showcasing India’s role as a global leader in diamond manufacturing, the report empowers consumers and retailers to make informed choices.”.
NDC is committed to sharing education and transparency throughout the natural diamond industry. Along with the Diamonds of Canada report, these studies will serve as additional assets to complement NDC’s Education Program giving retailers and consumers the information they need right at their fingertips.

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.
With The Soirée Collection, Zen Diamond redefines contemporary glamour — infusing timeless gold with modern edge and impeccable craftsmanship.

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.
