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.

De Beers Group Sets Out Portfolio and Organisational Actions to Support Long-Term Value Creation
Company outlines strategic cost optimisation, portfolio streamlining and operational changes to strengthen resilience while positioning for long-term growth in the natural diamond industry.
De Beers Group is advancing delivery of its business streamlining by setting out a number of planned portfolio and organisational changes to ensure an efficient cost base that strengthens resilience in the near-term while enhancing future competitiveness and retaining optionality as industry conditions improve.
Since 2024, De Beers has been streamlining its business in line with its Origins strategy to reduce costs, divest non-core assets and prioritise investment in activities that create the most value. Significant progress has been made, with more than $100 million of annual overhead costs removed from the business, the sale or closure of a number of non-core assets and significant capital and cost reconfigurations to asset expansion projects.
Simultaneously, De Beers has reinvested in natural diamond category marketing to support the industry’s efforts to grow natural diamond demand, launching new large-scale campaigns and collaborating with key stakeholders across the value chain to foster industry-wide investment. Global consumer demand for natural diamond jewellery returned to growth in 2025, while natural diamond sales increased across US independent jewellers in 2025 and into Q1 2026, led by higher value diamonds and those promoted by De Beers’ Desert Diamonds marketing campaign.
On the supply side, global rough diamond production is now decreasing, with several producers closing mines during 2026. Whilst the increasing rarity of diamonds and the emerging signs of improvement in consumer demand are likely to support longer-term value creation, rough diamond trading conditions are expected to remain challenging in the near-term due to cyclical and industry-specific factors.
Consistent with recent actions to improve business resilience, De Beers intends to pause production at the Venetia mine in South Africa for two years to reduce costs while also rephasing capital expenditure on its underground project. This will involve critical infrastructure investment to enhance the capacity and efficiency of the mine, with the intention to support future production growth as business and industry conditions improve.
De Beers is engaging with stakeholders in accordance with relevant requirements and the company’s values as it moves through this process, and will both support impacted employees and continue to invest in its community and Social and Labour Plan commitments.
This proposed action at Venetia Mine follows the decision earlier this year to pause the Tuzo Phase 3 expansion project at the Gahcho Kué Mine in Canada.
In parallel, De Beers plans to reconfigure its global operating model to refocus and prioritise resources on the core operational businesses and reduce its central corporate cost base.
Al Cook, CEO of De Beers Group, said:
“In line with our commitment to focus and streamline our business, we are making a number of changes to De Beers to ensure greater business resilience in the near-term, while supporting long-term value creation. We recognise the protracted challenging conditions as the diamond industry evolves, though we are encouraged by signs of consumer demand growth in the US and beyond, particularly in higher quality diamonds.
Global rough diamond supply is falling, bringing more support to the market. The changes we are making to our business are focused on underpinning our efficiency now and into the future, favourably positioning De Beers in its leadership role.”
De Beers Group will maintain current production levels through its other operations, and previous production guidance remains unchanged.
