Diamond Market Size & Trends

The global diamond market size was estimated at USD 41.49 billion in 2024, growing at a CAGR of 3.3% from 2025 to 2030. The industry's growth is mainly attributed to the rising demand for jewelry, especially in emerging economies such as China and India. The industry's value chain involves downstream, upstream, and midstream processes. The upstream process involves exploring, producing, and sorting rough diamonds. The midstream process involves cutting and polishing rough diamonds to produce the finished product. The downstream process involves jewelry design and setting from the polished diamond and its consequent retail sales.

Diamond Market Size, By Type, 2020 - 2030 (USD Billion)

As of 2024, Asia Pacific emerged as the second-largest market for diamonds after North America. The strong demand from millennials in the region mainly contributes to the growth of the diamond jewelry industry. This indicates a large potential for the market to expand further. Considering the growing potential for diamond jewelry in the region, existing industry players are making attempts to further invest and expand their target audience.

Drivers, Opportunities & Restraints

The key driver in the market is the growing consumer demand for ethical and sustainable products. As awareness around environmental impact and labor practices in mining increases, consumers increasingly favor lab-grown diamonds and responsibly sourced natural diamonds. The rise of millennials and Gen Z as major buying segments has further accelerated this shift, as these groups prioritize sustainability and ethical sourcing. For instance, companies like Brilliant Earth have capitalized on this trend by offering a wide range of conflict-free, ethically sourced diamonds, contributing to market expansion for lab-grown and responsibly sourced natural diamonds.

Despite the positive growth outlook, the market faces significant restraints due to the volatility of rough diamond prices and fluctuations in global economic conditions. Economic uncertainties, such as inflation and geopolitical tensions, directly impact diamond demand, particularly in high-end luxury segments. Moreover, the rise of synthetic diamonds, which are more affordable, is putting downward pressure on the pricing of natural diamonds, creating a price sensitivity that hinders the growth potential of traditional diamond producers.

The increasing trend of digitization and e-commerce presents a significant opportunity for the market. Online platforms and virtual try-on technologies have made purchasing diamonds more accessible and appealing, particularly to younger, tech-savvy consumers. Brands like Blue Nile and James Allen have expanded their reach by offering a seamless online shopping experience with virtual consultations and advanced 3D ring design tools. In addition, the rise of customization in diamond jewelry, where consumers can design their own pieces, provides a lucrative opportunity for both natural and lab-grown diamond producers to tap into a growing demand for personalized luxury products.

Price Trend Analysis

Diamond prices have remained volatile into 2024, influenced by factors like inflation, currency fluctuations, and shifting consumer preferences. After a rebound in 2023, diamond prices rose in the year's first half, driven by strong demand, but softened in the latter half due to economic uncertainties. In 2024, the market stabilizes but remains sensitive to global economic conditions, the rise of synthetic diamonds, and changing buying patterns. Manufacturers face pressure to adapt to these trends, with companies like Henan Huanghe Whirlwind and Sino-Crystal expanding into jewelry to capitalize on the growing demand for affordable and sustainable options.

Type Insights

They are rare and primarily used for jewelry applications. Finding and processing them involves complex processes, which makes them costly in the jewelry industry. Despite the challenges imposed by cheaper lab-grown jewelry counterparts, the allure of natural diamonds still exists and is predicted to remain in strong demand over the coming years.

The synthetic diamond segment is projected to grow at the fastest compound annual growth rate (CAGR) in the coming years, driven by advancements in production techniques like High-Pressure, High-Temperature (HPHT), and Chemical Vapor Deposition (CVD). These diamonds, primarily used for industrial applications such as cutting, drilling, and abrasives, have seen increasing adoption in the jewelry market due to significant reductions in production costs. Acceptance of synthetic diamonds in jewelry applications among millennials is gaining prominence in many countries. In addition, synthetic diamonds generally cost 30% to 40 % less than mined diamonds, which gives them a competitive edge over natural diamonds.

Application Insights

The growing middle-class population, coupled with the increasing spending power of millennials and Gen Z, are key factors contributing to the growth of this segment. As per De Beers Group, millennials represent almost 60% of the U.S. jewelry market, while millennials in China drive 80% of the total national demand for jewelry. Millennials tend to spend extra on travel experiences rather than luxury items. Thus, manufacturers and retailers are now actively considering the idea of attaching a story in their marketing campaigns that includes the lifecycle of a diamond from the mine to consumers.

Diamond Market Share, By Application, 2024 (%)

Lab-grown or synthetic products have considerably higher penetration in the industrial application segment. Industrial diamonds are mainly used as abrasives. Hence, their demand from sectors such as construction, metal machining, and exploration drilling has continuously increased over the past few decades. In construction, they are used in applications such as wire sawing, hand sawing, and core drilling.

Regional Insights

North America diamond market held over 51% revenue share of the global market. Ascending product demand for industrial applications is a key factor contributing to synthetic diamond penetration in this region. Under industrial application, the major sectors include machinery manufacturing, construction, and mining services (drilling and exploration for natural gas, oil, and minerals). Buildings, highways, stone cutting, and repair applications accounted for a majority of the consumption of synthetic diamonds for industrial purposes.
