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.

Global Diamond Market Showed Mixed Trends In March As The Middle East Conflict Escalates

How Scarcity In Large Stones and Geopolitical Shifting Are Redefining Luxury Value

Published

The global diamond industry continues to navigate a multifaceted landscape as the second quarter approaches. While geopolitical shifts and evolving supply chains have introduced new pressures, the market remains defined by a clear divergence in demand—favoring high-carat rarity and strategic retail consolidation.

The escalation of conflict in the Middle East during February 2026 has reverberated through major trading hubs. Iranian missile strikes created temporary disruptions in Israel and Dubai, traditionally the heartbeat of the rough diamond trade. In response, rough tender houses have demonstrated remarkable agility, relocating sales to maintain liquidity.

Despite these logistical hurdles, the industry’s infrastructure remains resilient, though Indian manufacturers continue to monitor access to rough supply closely as tender locations shift.

The RapNet Diamond Index (RAPI™) for March underscores a market divided by size and scarcity. While the “big stone” luxury segment remains robust, smaller goods are facing a period of price correction.

The March performance metrics reveal a period of strategic recalibration across the diamond market, characterized by a clear correlation between stone size and price volatility. Smaller categories faced the most pronounced headwinds, with 0.50-carat stones undergoing a significant 3.5% adjustment and 0.30-carat goods softening by 1.1%. Mid-range 1-carat diamonds continued a gradual correction with a 1.7% decline, reflecting a broader trend of cautious buying in the commercial segment.

In contrast, the high-end 3-carat category demonstrated remarkable resilience, slipping only 0.5% to remain relatively stable—a testament to the enduring appeal and scarcity of larger, investment-grade stones amidst shifting global dynamics.

Conversely, 2-carat stones and above are witnessing a supply-side squeeze. Long fancy shapes are experiencing heightened desirability, and New York wholesalers report a steady flow of retail orders for high-end, investment-grade diamonds.

At the source, De Beers is signaling a more exclusive approach to the market. Following its March sight—where prices for 5-carat rough and above reportedly increased—the miner announced a reduction in its sightholder base. For the contract period beginning July 1, the list will shrink by 20–25 clients, ensuring that supply is concentrated among the most strategically aligned partners.

In the retail sector, Signet Jewelers closed its fiscal year with a strong performance, reporting $6.81 billion in sales (a 1.6% year-on-year increase). This financial health is paired with a strategic rebranding: the integration of the James Allen platform into Blue Nile. This move signals a renewed commitment to the natural diamond sector, positioning Blue Nile as a premier destination for consumers seeking authentic, timeless luxury.

While the reduction of US tariffs on Indian goods to 10% provides some relief, the industry remains vigilant. As we move further into 2026, the focus for global players will undoubtedly remain on securing high-quality rough and catering to the unwavering demand for the market’s most significant, large-scale stones.
