Introduction
The Global lab-grown diamonds market is projected to reach approximately USD 29.3 billion by 2033, rising from a valuation of USD 14.2 billion in 2023. This growth is anticipated to occur at a compound annual growth rate (CAGR) of 7.5% during the forecast period from 2024 to 2033.
Lab-grown diamonds, also known as synthetic or cultured diamonds, are man-made gemstones produced through advanced technological processes such as High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD) that replicate the natural formation of diamonds. These diamonds possess the same physical, chemical, and optical properties as mined diamonds but are created in controlled laboratory environments, making them a sustainable and ethical alternative.
The lab-grown diamonds market refers to the global industry engaged in the production, distribution, and sale of these synthetic gemstones across various applications, primarily in jewelry, industrial tools, and electronics. In recent years, the market has experienced notable expansion, driven by increasing environmental awareness, shifting consumer preferences toward sustainable luxury, and advancements in diamond synthesis technologies that have significantly improved product quality and reduced production costs.
Moreover, the affordability of lab-grown diamonds typically 30% to 40% less expensive than their mined counterparts—is contributing to their rising adoption among millennials and Gen Z consumers. The demand is also bolstered by the growing presence of lab-grown diamonds in mainstream retail channels and high-end fashion brands, further legitimizing the product in the luxury goods segment. An additional growth opportunity lies in their potential use in semiconductors and thermal conductors, where synthetic diamonds offer superior hardness and heat dissipation properties. With increasing regulatory scrutiny on ethical sourcing and a broader industry push toward sustainability, lab-grown diamonds are positioned as a viable solution to the environmental and ethical concerns surrounding traditional diamond mining. Consequently, the market is expected to witness sustained growth over the forecast period, with Asia-Pacific and North America emerging as key regions of opportunity.

Regional Analysis
North America Leads Lab-Grown Diamonds Market with Largest Market Share of 36.4%
North America has emerged as the dominant region in the global lab-grown diamonds market, accounting for 36.4% of the total market share in 2024, with a market valuation of USD 5.17 billion. This leadership is primarily driven by the United States, which alone contributed approximately USD 7.1 billion to the regional market in 2024.
The region’s growth is propelled by increasing consumer preference for sustainable and ethically sourced diamonds, particularly among millennials and Gen Z demographics. Lab-grown diamonds have gained significant traction in the engagement ring segment, reflecting a broader shift towards environmentally conscious purchasing decisions.
However, the market faces challenges due to recent U.S. trade policies. The imposition of a 10% import tariff on diamonds has disrupted global trade dynamics, affecting major suppliers like India, which processes over 80% of the world’s diamonds. These tariffs have led to decreased demand and financial strain within the industry, with reports of significant job losses and reduced exports from key processing hubs such as Surat.
Industry leaders, including De Beers, have criticized these tariffs, highlighting their potential to harm U.S. consumers and the domestic jewelry sector without offering tangible benefits to American employment. This growth underscores the region’s resilience and the increasing consumer inclination towards sustainable luxury products.
