Diamond Market Forecasts to 2030 – Global Analysis By Type (Natural Diamonds and Synthetic Diamonds), Product (Rough Diamonds and Polished Diamonds), Cut, Color, Application and By Geography

According to Stratistics MRC, the Global Diamond Market is accounted for $43.11 billion in 2024 and is expected to reach $58.77 billion by 2030 growing at a CAGR of 5.3% during the forecast period. Diamond is a crystalline carbon that is renowned for its remarkable thermal conductivity, hardness, and brilliance. It develops over millions to billions of years deep within the Earth's mantle under conditions of intense heat and pressure. Because of its unmatched hardness, diamond is frequently used in industrial processes like drilling, grinding, and cutting. Moreover, diamonds have many industrial applications, but they are also prized as gemstones that represent commitment and luxury in jewellery. For both industrial and commercial applications, synthetic diamonds made using chemical vapor deposition (CVD) and high-pressure high-temperature (HPHT) techniques have become more and more popular.

According to the Kimberley Process Certification Scheme (KPCS) emphasizes collecting and publishing data relating to actual mining and international trade in diamonds. Member countries are required to officially submit statistics that can be verified through audit. In 2006, the KPCS monitored $35.7 billion in rough diamond exports, representing more than 480 million carats.

Market Dynamics:

Driver:

Growing interest in bridal and luxury jewellery

Diamonds are a popular choice for wedding bands, engagement rings, and statement jewelry pieces because they have long been connected to love, commitment, and luxury. The demand for upscale jewelry has increased due to the growing wealth of the middle class, especially in developing nations like China and India. Additionally, to meet the growing demand from consumers, international luxury brands like Cartier, Tiffany & Co., and Harry Winston are constantly launching unique diamond collections. Diamonds are a status and prestige symbol, and aspirational purchases are further fueled by social media influence and celebrity endorsements.

Restraint:

High price and economic unpredictability

Due to their high price, diamonds are considered luxury goods that are susceptible to changes in the economy. Diamond sales are impacted by a decline in discretionary spending during economic downturns, especially in non-essential markets like luxury jewelry. Purchasing power is further impacted by market volatility, inflation, and currency depreciation in important consumer regions such as the United States, China, and India. Furthermore, because middle-class consumers view diamonds as a luxury, they frequently choose lab-grown diamonds or other gemstones, which restricts the growth of natural diamond sales.

Opportunity:

Growth of the lab-grown diamond industry

The market for diamonds in general has a significant growth opportunity due to the lab-grown diamond industry's rapid expansion. These diamonds offer a sustainable and affordable substitute for diamonds that are mined, owing to cutting-edge processes like Chemical Vapor Deposition (CVD) and High-Pressure High-Temperature (HPHT). Moreover, demand for lab-grown diamonds is rising as a result of growing consumer awareness of ethical sourcing and environmental impact, particularly among Gen Z and millennials. As technology continues to improve production efficiency, major jewelry brands are now including lab-grown diamonds in their collections, making them more widely available and reasonably priced.

Threat:

Growing rivalry from lab-grown diamonds

The conventional diamond market is now seriously threatened by lab-grown diamonds. Improvements in Chemical Vapor Deposition (CVD) and High-Pressure High-Temperature (HPHT) technologies have made lab-grown diamonds more sustainable, less expensive, and almost identical to natural diamonds. Lab-grown diamonds are becoming more and more popular among younger consumers, particularly millennials and Gen Z, because of their ethical and environmental benefits. Additionally, natural diamond prices and sales are under pressure as a result of the increasing use of these diamonds in fashion accessories, fine jewelry, and engagement rings.

Covid-19 Impact:

The COVID-19 pandemic significantly affected the diamond market by interfering with international supply chains, mining activities, and retail sales. Demand fell precipitously as a result of the temporary closure of mines, manufacturing facilities, and jewellery stores brought on by lockdowns and travel restrictions, especially in the luxury jewellery market. The cancellation of social gatherings and weddings further decreased diamond purchases by consumers. But as brands embraced virtual consultations and e-commerce platforms, the market showed a shift toward digital retailing, with online diamond sales rising. Furthermore, the pandemic's economic unpredictability fuelled interest in diamonds as a substitute asset for traditional investments.

The Natural Diamonds segment is expected to be the largest during the forecast period

The Natural Diamonds segment is expected to account for the largest market share during the forecast period due to their rarity, historical significance, and luxury appeal, natural diamonds account for the majority of global sales. They are valued for their brilliance, uniqueness, and investment potential, and they dominate the jewelry industry, particularly for engagement rings and high-end collections, because consumers continue to associate them with exclusivity and status. Moreover, the industry is driven by leading mining companies such as De Beers, Alrosa, and Rio Tinto, which ensure a steady supply through responsible sourcing initiatives.

The Polished Diamonds segment is expected to have the highest CAGR during the forecast period

Over the forecast period, the Polished Diamonds segment is predicted to witness the highest growth rate. Growing consumer demand for fine jewellery and rising disposable incomes in emerging economies are expected to fuel significant growth in this market's polished diamond segment. Additionally, the jewellery industry has a strong demand for polished diamonds, which have undergone cutting and finishing procedures to improve their brilliance and visual appeal. In nations like China and India, the growing middle class and the rising demand for diamond jewellery serve to further support this demand.

Region with largest share:

During the forecast period, the North America region is expected to hold the largest market share. The main factors influencing this dominance are high disposable incomes and a deep cultural connection to diamond jewelry, especially in the US, which accounts for more than half of the world's diamond demand. The region's dominant position is further reinforced by its customer preference for luxury goods and its well-established retail infrastructure. Furthermore, the use of synthetic diamonds for industrial purposes such as mining services, construction, and machinery manufacturing has increased significantly in North America, which has helped to account for its sizeable market share.

Region with highest CAGR:

Over the forecast period, the Asia-Pacific region is anticipated to exhibit the highest CAGR. The growing demand for diamond jewellery in developing nations like China and India, where rising disposable incomes and changing consumer preferences fuel increased market activity, is the main driver of this growth. Moreover, the region's substantial manufacturing capabilities, especially in China and India, support its position in the markets for lab-grown and natural diamonds. These factors all combine to make the Asia-Pacific region a key global driver of the diamond industry's growth.
