The global CVD Lab-grown Diamonds Market was valued at USD 13.18 billion in 2024 and is expected to grow from USD 14.07 billion in 2025 to USD 25.58 billion by 2034, at a CAGR of 6.9% during 2025–2034, according to Polaris Market Research. CVD lab-grown diamonds are synthetic diamonds produced through a controlled process that replicates the natural diamond formation environment. Growing interest in sustainability is driving demand for CVD diamonds as an eco-friendly alternative to mined diamonds, reducing the environmental degradation and ethical concerns associated with traditional mining. They are gaining traction in both the jewelry and industrial sectors.

How Chemical Vapor Deposition Works

In the chemical vapor deposition method described in the report, diamond seed crystals are placed in a chamber with heated carbon-containing gas, allowing carbon to deposit layer by layer over several weeks. The resulting stones are chemically and physically identical to natural diamonds and are indistinguishable without specialized tools. ABD Diamonds, an India-based company established in 2017, specializes in CVD and HPHT diamonds produced using chemical vapor deposition, and offers diamond jewelry, loose diamonds and industrial diamonds.

Changing Preferences Favor Ethical Sourcing

Younger consumers in particular are shifting away from mined diamonds because of concerns about environmental impact and labor practices. Modern buyers prioritize ethical sourcing, affordability and customization, and CVD diamonds offer a sustainable, cost-effective alternative without compromising on quality, clarity or brilliance. As brand perception and consumer trust strengthen, acceptance in luxury and mainstream markets continues to grow. In April 2024, Brilliant Earth collaborated with Dr. Jane Goodall and the Jane Goodall Institute, with a USD 100,000 donation and a recycled gold collection, highlighting the industry's shift toward ethical sourcing and responsible practices in fine jewelry.

Colorless Stones Dominate by Color

The colorless segment dominated the market in 2024 because of high demand in the jewelry and industrial sectors. Consumers seeking an alternative to natural diamonds prefer colorless CVD diamonds for their optical purity, brilliance and near-identical appearance to mined stones. Jewelers and luxury brands increasingly incorporate colorless CVD diamonds into high-end collections, and advances in CVD technology have improved the production efficiency of high-quality stones.

North America Leads the Regional Landscape

North America dominated the revenue share in 2024, driven by strong consumer demand, technological advancements and a well-established jewelry industry. High awareness of sustainable and ethically sourced products supports adoption. In 2024, US domestic production of industrial diamond bort, grit and powder reached 160 million carats valued at USD 53 million, a 5% increase from 2023, with synthetic diamonds accounting for 99% of consumption. Major jewelry brands in the US and Canada have actively promoted CVD diamonds, and the region hosts leading manufacturers and research institutions focused on the technology.

Competitive Landscape and Key Players

Global leaders and regional players compete through innovation, strategic alliances and geographic expansion, using mergers and acquisitions, partnerships with jewelry brands and new diamond-growing technologies. Regional companies address localized demand with cost-effective, customized solutions in emerging markets. In December 2024, Limelight Diamonds opened its first retail store in Chennai and announced plans for seven more stores by year-end to meet rising demand for lab-grown diamond jewelry. Key players include:

• ABD Diamonds
• Anjali Diamonds Pvt Ltd
• BHANDERI LAB GROWN DIAMONDS
• De Beers plc
• Delaware Diamond Knives, Inc.
• Hebei Plasma Diamond Technology Co., Ltd.
• IIa Technologies
• Ritani
• Shanghai Zhengshi Technology
• SP3 Technologies LLP
• VIBRANIUM LAB

Conclusion

The CVD Lab-grown Diamonds Market is projected to reach USD 25.58 billion by 2034 at a 6.9% CAGR. The maturity of chemical vapor deposition, the priority placed on ethical sourcing, the appeal of colorless CVD diamonds, the strength of the jewelry sector and the leadership of North America together outline where value is being created.
