Lab Grown Diamonds Market Size, Share, Trends, Industry Analysis, and Forecast (2025 – 2031)

Lab Grown Diamonds Market Size

The global lab grown diamondsmarket size was valued at $28.56 billion in 2025 and is projected to reach $53.99 billion by 2031, growing at a CAGR of 11.2% during the forecast period.

Lab Grown Diamonds Market Overview

Lab-grown diamonds are created in controlled laboratory environments using advanced technologies that replicate the natural processes by which diamonds form deep within the Earth. These diamonds are chemically and physically identical to mined diamonds but are produced much more quickly and sustainably, typically taking weeks rather than billions of years. The growing demand for lab-grown diamonds is largely driven by increasing consumer awareness of ethical and environmental issues associated with traditional diamond mining, as well as significant advancements in production technologies such as Chemical Vapor Deposition (CVD) and High-Pressure High-Temperature (HPHT) methods.

Companies can benefit from this trend by capitalizing on the rising consumer preference for sustainable and affordable alternatives to natural diamonds. For instance, Goldiam International, a key player in the lab-grown diamond market, reported revenue of approximately Rs 554.29 crore in the last fiscal year, with a significant portion attributed to their lab-grown diamond jewelry offerings. Additionally, the Indian government’s Production-Linked Incentive (PLI) scheme is fostering growth in this sector, further enhancing the competitive landscape.

Lab Grown Diamonds Market Dynamics

The lab grown diamondsmarket is expected to witness significant growth in the future due to the increasing consumer demand for sustainable and ethically sourced jewelry, technological advancements in production methods, and affordability of lab-grown diamonds, typically 30-40% less expensive than mined diamonds. However, the consumer perception issues regarding the value and authenticity of lab-grown diamonds compared to natural diamonds, ongoing competition from the traditional natural diamond market promoting its uniqueness and heritage, and price erosion due to increased production capabilities and market entry of new players are restraining the growth of the market.

Furthermore, growing interest in personalized and customizable jewelry options using lab-grown diamonds, increasing demand for lab-grown diamonds in industrial applications beyond jewelry, and potential for expansion in emerging markets with rising disposable incomes, such as India and China are the key trends propelling the lab grown diamondsmarket.

Increasing Consumer Demand for Sustainable and Ethically Sourced Jewelry is Driving the Lab Grown Diamonds Market

The increasing consumer demand for sustainable and ethically sourced jewelry is significantly impacting the lab grown diamondsmarket, by driving both innovation and market expansion. This surge is reflected in the actions of major jewelry brands;

• For instance, Tiffany & Co. launched a new collection featuring lab-grown diamonds, signaling a strong endorsement of this trend.
• Additionally, Pandora announced in 2023 that it would stop using mined diamonds altogether, focusing exclusively on lab-grown options to meet rising consumer demand for ethical products.
• Similarly, Prada introduced its first collection featuring lab-grown diamonds in March 2024 as part of its commitment to sustainability, showcasing innovative designs and materials, including certified recycled gold.
• Furthermore, Kendra Scott debuted its Lab Grown Diamond Collection on March 25, 2024, offering fine jewelry styles at more accessible price points, which aligns with consumer preferences for ethical sourcing and affordability.

The acceptance of lab-grown diamonds is also evident in the retail sector;

• Macy's and Blue Nile have expanded their offerings to include lab-grown diamonds due to heightened customer demand.

Approximately 70% of Millennials and Gen Z consumers prefer lab-grown diamonds for their ethical and environmental benefits, as these diamonds generate 85% less carbon emissions compared to mined counterparts. This shift towards sustainability is not just a trend but a transformative movement within the jewelry industry, positioning lab-grown diamonds as a mainstream choice for modern consumers seeking luxury without compromising their values.

By Size, the 2-4 Carat Segment is projected to be the Largest Segment in the Lab Grown Diamonds Market

2-4 carat is the largest segment in the lab grown diamondsmarket, driven by rising consumer preferences for larger, ethically sourced stones, particularly among Millennials and Gen Z. This demographic is increasingly prioritizing sustainability and affordability, with lab-grown diamonds typically priced 30-40% lower than their mined counterparts.

Companies are actively responding to this trend;

• For instance, Brilliant Earth launched a new collection of 2-4 carat lab-grown diamond engagement rings in January 2024, emphasizing ethical sourcing and customizable options.
• Additionally, James Allen introduced a line of lab-grown diamonds in the same carat range in March 2024, catering to consumers looking for high-quality yet affordable options.
• Government initiatives also support this growth; in 2023, the Indian government announced a promotional scheme aimed at enhancing the production of lab-grown diamonds, which is expected to increase availability and drive down prices further.

As consumer awareness regarding the environmental impact of mined diamonds continues to rise, coupled with advancements in production technology that have reduced costs by up to 40%, the 2-4 carat segment is well-positioned for robust growth in the coming years.

By Geography, North AmericaHolds the Largest Share in the Market Revenue

North America holds the largest share of the lab grown diamondsmarket, driven by a significant shift towards sustainability and ethical sourcing among consumers. This growth is largely fueled by consumer preferences, particularly among Millennials and Gen Z, with around 70% of these demographics favoring lab-grown diamonds due to their ethical implications and lower environmental impact, generating 85% less carbon emissions than mined diamonds.
