Combined, these demand factors and technological investments are boosting global market value, with substantial growth projected toward the end of the decade.
Lab-Grown Diamonds Boom: CVD on the Rise
The most dynamic area of the market is lab-grown diamonds. The CVD (chemical vapor deposition) segment is growing much faster than the traditional sector. Specialized estimates show that the global CVD diamond market reached USD 3,531.4 million in 2024 and could exceed USD 3,902.2 million in 2025 (CAGR ≈10.5%) globalgrowthinsights.com. This boom is driven by several factors:
- Traceability and sustainability: Lab diamonds are seen as more ecological and ethical alternatives. They don’t require extensive mining, reducing deforestation and carbon emissions. Modern processes allow easy certification of origin, increasing buyer confidence, especially among younger generations.
- Affordable pricing: The cost of producing CVD diamonds has dropped significantly in recent years. This price decline enhances their appeal, allowing for larger or higher-quality gems at the same budget.
- Near-identical quality: Chemically and visually, CVD diamonds are virtually identical to natural ones. They offer the same hardness and brilliance with less environmental impact. This combination of high quality and ethical value is shifting market preferences.
Interest in lab-grown diamonds is growing for both jewelry and technology. This segment is expected to maintain double-digit growth, far surpassing the natural stone market. Its expansion is also reflected in rapid adoption in electronics: today, over 45% of CVD consumption is used in high-performance components like semiconductors and thermal dissipators. At the same time, lab-grown diamond jewelry is positioning itself as an ethical, modern option complementing the traditional segment.
North America and Asia: Global Market Leaders
The geographic distribution of the diamond market shows clear global leaders. North America dominates the natural diamond segment, holding about 55.3% of the global market in 2024. This is due to the high purchasing power of U.S. and Canadian consumers and the popularity of luxury jewelry in the region. Meanwhile, Asia-Pacific (especially China and India) leads in synthetic diamonds production and consumption, fueled by rapid industrial growth and adoption of new tech applications. This geographic duality reflects a diverse global market: North America reinforces the luxury status of natural diamonds, while Asia drives lab-grown development through innovation and mass demand.
Applications and Use Diversification
Diamonds remain versatile across multiple industries:
- Natural diamonds: Still the luxury standard in fine jewelry (rings, necklaces, high-end watches). Their unmatched hardness also makes them indispensable in industrial applications: saws, diamond-tipped drills, cutting disks, and abrasives for precision machining. In short, mined diamonds serve both ornamental and high-performance tool functions.
- CVD and HPHT diamonds: Rapidly expanding in high-tech sectors. Now increasingly used in the electronics and semiconductor industries (e.g., thermal dissipator sheets in power devices) and precision optics. They’re also utilized in specialized cutting tools, medical equipment, and advanced research projects. In jewelry, their lower cost and ethical value make them appealing to a broad audience. Altogether, application diversification (from computer circuits to quantum sensors) boosts commercial interest in lab-grown diamonds alongside natural ones.
Challenges and Opportunities for the Sector
- Key opportunities:
