Synthetic Diamond Market Analysis by Mordor Intelligence

The Synthetic Diamond Market size is estimated at USD 25.49 billion in 2025, and is expected to reach USD 33.48 billion by 2030, at a CAGR of 7.91% during the forecast period (2025-2030). Escalating demand from telecommunications, electric vehicles, aerospace, and high-precision manufacturing is accelerating revenue streams, while persistent sustainability mandates are steering customers away from mined stones toward engineered alternatives. Asia Pacific, already supplying most diamond wafers and super-abrasive tools, benefits from generous state incentives and surging electronics exports. Competition is intensifying because technology-focused entrants are scaling Chemical Vapor Deposition (CVD) capacity that can achieve device-grade purity, posing a direct challenge to the incumbent High Pressure High Temperature (HPHT) model. Meanwhile, luxury brands in the Gulf Cooperation Council are leveraging fancy-color lab-grown stones to satisfy environmentally conscious consumers, widening the addressable base beyond traditional bridal jewelry. Regulatory uncertainty and uneven certification standards remain the chief headwinds, especially as retail price corrections undermine perceived resale value among end users, but the performance-driven high-tech arena continues to shield margins.

Key Report Takeaways

  • By product type, rough stones led with 66% of the synthetic diamond market share in 2024, while polished diamonds are set to post a 9.84% CAGR through 2030. 
  • By manufacturing process, HPHT accounted for 60% of the synthetic diamond market size in 2024; CVD is projected to expand at 11.1% CAGR between 2025-2030. 
  • By geography, Asia Pacific commanded 56% revenue share of the synthetic diamond market in 2024 and is forecast to advance at an 8.35% CAGR to 2030.

Segment Analysis

By Product Type: Rough Stones Dominate, Polished Gems Accelerate

Rough stones captured 66% of the synthetic diamond market share in 2024, owing to heavy uptake in construction, oil-and-gas drilling, and precision cutting tools, all of which leverage unmatched hardness and thermal conductivity. The U.S. Geological Survey recorded domestic output of 160 million carats valued at USD 53 million, a 5% rise on the prior year.

Polished stones, though smaller in tonnage, are the fastest-expanding category at a projected 9.84% CAGR. Wider consumer acceptance, heightened design flexibility, and advances in plasma post-processing that enhance color saturation are boosting volumes across mid-tier jewelry chains. The Gemological Institute of America notes that CVD submissions now exceed HPHT samples, with fancy colors and 3-carat-plus stones up sharply year over year. Over the forecast horizon, polished gems are expected to secure incremental shelf space in omnichannel retail, even as wholesale prices stabilize.

By Manufacturing Process: HPHT Scale Meets CVD Purity

HPHT retained 60% of the synthetic diamond market size in 2024, benefiting from established presses, predictable cycle times, and suitability for industrial grades where minute inclusions are tolerable. The method’s high throughput keeps unit costs attractive for drill-bit matrices and wire-drawing dies. However, HPHT competes less effectively in electronics and photonics, where defect densities are critical. 

CVD is on track for an 11.1% CAGR to 2030. Low-pressure reactors produce layers with nitrogen concentrations below 5 ppb, unlocking electron mobility regimes needed for power devices operating above 10 kV. GIA documented a 75.33-carat single-crystal CVD stone at the 2024 JCK Las Vegas show, underscoring scale improvements. The 2024 collaboration between Element Six and Orbray targets wafer-scale substrates for advanced AI accelerators, illustrating how the process is migrating up the value chain.

Geography Analysis

Asia Pacific anchored 56% of global revenue in 2024 and continues to post the fastest regional growth at an 8.35% CAGR through 2030. Production clusters in Henan, Shandong, and Gujarat host vertically integrated operations that span seed synthesis to finished jewelry. China’s dominance in lab reactors provides cost advantages, while India’s abolition of a 5% import duty on diamond seeds attracts overseas joint ventures. 

North America remains pivotal for high-performance applications, particularly in quantum sensing and wide-band-gap power electronics. Adamas One Corp’s South Carolina facility, which currently runs 12 reactors producing 3,000 rough carats monthly, emphasizes IP-protected growth protocols to secure aerospace and medical contracts.

Europe maintains a stable but innovation-oriented stance. German toolmakers and French photonics startups incorporate diamond inserts to meet automotive lightweighting mandates. The United Kingdom’s academic ecosystem, notably the National Quantum Computing Centre, advances Nitrogen-Vacancy (NV) defect engineering for secure communications. Outside Europe, the Middle East positions Dubai as a trading and production hub.

Competitive Landscape

Global competition is moderately fragmented as established conglomerates defend industrial niches while growth-stage firms attack high-margin electronics. Element Six, a De Beers Group subsidiary, leverages decades of process optimization to ship super-abrasives and optical-grade plates. Technology disruptors are capitalizing on the superior thermal and electrical properties of the material. Diamond Foundry’s wafer-based EV inverter achieves sixfold volumetric shrinkage over benchmark silicon carbide units yet delivers higher power density, signaling potential for drivetrain re-architecture.
