The lab grown diamond industry in India is experiencing explosive growth, with these modern gems now accounting for nearly 15% of India’s total diamond sales in 2025. Once seen as a niche alternative to mined stones, lab-created diamonds are quickly becoming mainstream—reshaping how consumers think about luxury, ethics, and affordability.
This shift isn’t just a passing trend. It’s a full-scale transformation driven by technology, changing buyer preferences, and strong government support. In this blog, you’ll discover what’s fueling this boom, who the major players are, the challenges ahead, and how you can make smarter buying decisions.
India’s journey into lab-grown diamonds began quietly in the early 2010s, when a handful of small labs started experimenting with diamond synthesis. At the time, the market was limited, and consumer awareness was low.
The turning point came in 2018, when policy changes made it easier to import raw materials and machinery required for production. This significantly lowered entry barriers for manufacturers.
According to Dr. Raj Patel from the Gem & Jewellery Export Promotion Council (GJEPC):
“Labs cut costs by 40% right away.”
This cost advantage allowed Indian producers to scale quickly and compete globally.
The growth of lab-grown diamonds is powered by two key technologies:
CVD (Chemical Vapor Deposition): Builds diamonds layer by layer using carbon-rich gases.
HPHT (High Pressure High Temperature): Mimics the natural conditions under which diamonds form deep within the Earth.
These processes produce diamonds that are chemically, physically, and optically identical to mined diamonds.
By 2026, India is expected to operate over 20 large-scale production facilities, with output increasing by an astonishing 300% between 2020 and 2025.
One of the biggest reasons behind the surge in popularity is pricing.
Lab-grown diamonds are typically 70–90% cheaper than their mined counterparts. This affordability opens the market to a much wider audience.
Additionally, unlike mined diamonds, lab-grown stones offer an unlimited supply, eliminating concerns about scarcity.
Key takeaways for buyers:
Get larger stones for the same budget
Ideal for engagement rings and wedding jewelry
Better value without compromising quality

In cities like Mumbai, lab-grown diamonds are increasingly featured in modern weddings, replacing traditional mined stones.

The Indian government has played a major role in accelerating growth.
Export incentives doubled in 2024, making Indian diamonds more competitive globally
Infrastructure support boosted manufacturing hubs
A prime example is Surat, which has emerged as the epicenter of lab-grown diamond production. The cluster has seen a 5x increase in jobs, creating thousands of employment opportunities.
Several companies are spearheading India’s dominance in this space.
IIa Technologies, for instance, established India’s largest lab-grown diamond facility in 2023. By 2025, the company produced over 1 million carats annually.
CEO Anita Rao stated:
“We’re just starting.”
This optimism reflects the massive untapped potential in both domestic and export markets.
The boom isn’t limited to large corporations.

Despite rapid growth, the industry faces a few significant challenges:
Fake or low-quality stones entering the market
Limited financing support from traditional banks
Rising consumer skepticism
In fact, 10% of returns in 2025 were due to quality concerns, highlighting the need for stricter standards.
To address these issues, industry bodies are taking action:
GJEPC is pushing for mandatory certification standards
Training programs aim to upskill 10,000+ workers in grading and production
Increased awareness campaigns for consumers
Pro tip for buyers:
Always purchase diamonds certified by trusted organizations like IGI (International Gemological Institute) or GIA (Gemological Institute of America).
The future looks incredibly promising.
The market is projected to reach $2 billion by 2030
