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.

Fancy Colour Diamond prices soar 205% since 2005 amid growing luxury demand, Says NDC
Prices for fancy colour diamonds have surged by an impressive 205% since 2005, according to a new report by the Natural Diamond Council (NDC), in collaboration with Choron Group and the Fancy Color Research Foundation (FCRF).

These exceptionally rare gems—known for their vivid hues of pink, blue, yellow, green, and red—now rank among the most sought-after and resilient assets in the natural diamond market.
Representing just 0.01% of all natural diamonds mined, fancy colour diamonds have captured growing interest from collectors, luxury jewellery houses, and investors. Data from the FCRF shows that pink diamonds have skyrocketed in value by nearly 394% over the past two decades, while blue diamonds have risen by over 240%, and yellow diamonds by almost 50%. Overall, fancy colour diamonds have posted a compound annual growth rate (CAGR) of 5.7%.
Once considered a niche category, these vibrant stones now feature prominently in high-profile auctions and luxury jewellery collections. Recent standout sales include the 10.03-carat Mediterranean Blue diamond, which fetched $21.4 million at Sotheby’s Geneva—more than $2.1 million per carat—and the historic 10.38-carat Marie-Thérèse Pink, sold at Christie’s New York for nearly $14 million.
Auction houses are increasingly showcasing a broader selection of fancy colour diamonds, driven by both aesthetic allure and their perceived long-term investment value, especially in today’s uncertain economic climate.
Supply remains extremely limited, with fancy colour diamonds mined in only a few regions globally—such as Canada, Botswana, South Africa, Sierra Leone, and the now-closed Argyle mine in Australia—adding to their exclusivity.
As luxury consumers place greater emphasis on rarity, provenance, and artistry, fancy colour diamonds are expected to maintain their prominence. With upcoming events like Paris Haute Couture Week, these extraordinary gems are poised to continue leading trends in high jewellery, elite auctions, and alternative investments.

ALROSA’s Severalmaz ramps up output as Karpinsky-2 diamond pipe enters development
Russian diamond giant ALROSA has begun full-scale development of the Karpinsky-2 kimberlite pipe at the M.V. Lomonosov diamond field in the Arkhangelsk region, marking a major step forward for its local subsidiary, Severalmaz. Karpinsky-2 becomes the third active pipe at the site, alongside the existing Arkhangelsk and Karpinsky-1 operations.

Karpinsky-2 holds more than 40 million tonnes of diamond-bearing ore and was first evaluated in 2018 through pilot mining operations, which confirmed its commercial viability. Preparatory work for full development began earlier this year, and the project officially moved into the design phase during a recent visit by ALROSA CEO Pavel Marinychev.
Marinychev, who personally launched the design stage, also assessed Severalmaz’s performance for 2025 during his visit. In the first five months of the year, the company surpassed its ore extraction targets and improved operational efficiency, resulting in a 9.4% increase in ore processing. These gains translated into the production of more than 1.2 million carats of rough diamonds.
The CEO also reviewed progress on a new water recycling system at the Lomonosov processing plant and emphasized the importance of completing a gym facility for workers at the shift village by year-end, highlighting the company’s focus on both sustainability and employee well-being.
“I am sure that the work of the Severalmaz team will drive the enterprise’s continued growth. We remain committed to providing safe working conditions and contributing to the development of the Arkhangelsk region,” Marinychev stated.
ALROSA, which produces about 30% of the world’s diamonds and 90% of Russia’s output, reported production of 33 million carats in 2024. The company’s proven reserves exceed 1 billion carats, solidifying its position as the global leader in diamond mining.
