The global diamond market represents a critical segment of both the luxury goods industry and industrial manufacturing due to the material's unmatched hardness, durability, and optical properties. According to report-year data, the diamond market size was valued at USD 102.06 billion in 2025. The market increased to USD 106.76 billion in 2026 and is projected to reach USD 153.1 billion by 2034, reflecting consistent expansion driven by jewelry consumption and industrial applications. North America dominated the global diamond market with a 55% market share in 2025, supported by high disposable income and strong demand for wedding and luxury jewelry. The U.S. diamond market is projected to grow significantly, reaching USD 68.64 billion by 2032, largely due to rising global jewelry consumption.
Diamonds are among the hardest naturally occurring materials and are widely recognized as gemstones. Market growth is supported by increasing use in jewelry manufacturing, industrial cutting and drilling, construction, and research applications where extreme hardness, thermal conductivity, and optical dispersion are required. The unique properties of diamonds allow their use across both luxury and functional industries, supporting long-term market demand.
Impact of COVID-19 on the Diamond Market
The COVID-19 pandemic disrupted the diamond market globally due to mine closures, limited polishing and cutting operations, and supply chain interruptions. Key diamond-producing and consuming countries, including the U.S., India, China, and Russia, imposed lockdowns that affected mining, manufacturing, and jewelry retail operations. Although demand weakened during the pandemic period, the market gradually recovered and returned to pre-pandemic levels. China played a significant role in global recovery due to its rapid economic rebound and strong consumer demand.
Diamond Market Trends
A major trend shaping the market is the rising demand for innovative and customized jewelry designs, driven by changing consumer preferences. Consumers increasingly favor colorful and unique jewelry pieces, creating strong opportunities for both natural and synthetic diamond producers. The rapid growth of online jewelry platforms has further boosted consumption, as customers increasingly prefer digital purchasing channels for convenience and time savings. The growing acceptance of lab-grown diamonds has also expanded the consumer base, particularly among younger buyers.
Diamond Market Growth Factors
Growing Demand from the Jewelry Industry
Diamonds have long been associated with luxury, weddings, and special occasions. Their exceptional thermal conductivity, optical brilliance, and durability continue to drive demand from the jewelry sector. Rising disposable income, increased influence of fashion trends, and expanding bridal jewelry markets are key drivers. Lab-grown diamonds, which are physically and chemically identical to mined diamonds, are gaining popularity due to affordability and ethical considerations, further supporting market growth.
Expanding Industrial Applications
Diamonds play a vital role in industrial cutting, grinding, drilling, and polishing tools. Diamond-based cutting tools are widely used to machine hard materials such as tungsten carbide, granite, ceramics, and high-silicon aluminum. Rapid industrialization, infrastructure development, and increasing demand for precision tools are driving growth in industrial diamond consumption worldwide.
Market Restraints
The high price volatility of natural diamonds remains a key restraining factor. Rising costs from mining to retail, currency fluctuations, limited production, and international trade regulations have made natural diamonds less affordable for middle- and lower-income consumers. Polished diamonds remain significantly more expensive than rough stones, limiting broader adoption in certain applications and regions.
By Type
The market is segmented into natural and synthetic diamonds. The synthetic diamond segment dominated with a 96.97% share in 2026, driven by lower costs, wide availability, and extensive use in construction and industrial tools. Synthetic diamonds are also increasingly adopted in jewelry, particularly for weddings, influenced by Western cultural trends.
By Product
Based on product, the market is segmented into rough and polished diamonds. The rough diamond segment accounted for 76.63% of the market share in 2026, supported by its lower cost and widespread use in drilling equipment, cutting tools, and optical grinding wheels. Polished diamonds continue to gain traction in jewelry applications.
By Application
The jewelry segment dominated the market with a 94.79% share in 2026, driven by rising disposable income, brand expansion, and social media influence. The industrial segment benefits from increased mining, construction, and manufacturing activity, particularly in developing economies.
