India’s diamond industry reached a turning point in FY26 as lab-grown diamond export volumes hit 18.84 million carats, surpassing natural stone exports of 16.00 million carats for the first time. This shift highlights growing consumer interest in affordable synthetic options, putting significant pressure on the pricing and long-term outlook for traditional natural diamond manufacturers.
India’s diamond sector is undergoing a major structural transformation. For the first time, the volume of lab-grown diamonds (LGDs) exported from India has exceeded that of natural polished diamonds. In the fiscal year ending 2026, India exported 18.84 million carats of lab-grown stones, compared to 16.00 million carats of natural diamonds. This crossover in export volumes marks a departure from the traditional dominance of mined diamonds and reflects how quickly consumer choices are changing.
The decline in the value of natural diamond exports adds to the industry's challenges. Export values for natural diamonds fell to $12.16 billion in FY26, a significant drop from the $24 billion peak seen in FY22. While credit rating agency ICRA projects a modest growth of 6-8% for the broader diamond export sector in FY27, the outlook remains negative due to persistent pricing volatility and intense competition from cheaper synthetic alternatives. The price for lab-grown diamonds has also seen a sharp correction, dropping to approximately $71 per carat in early 2026, which makes them highly attractive to cost-conscious buyers.
Regulatory Focus on Market Integrity
To manage this transition and protect consumer trust, regulatory action has tightened. In January 2026, the Bureau of Indian Standards (BIS) implemented the IS 19469:2025 standard. This regulation is designed to clearly differentiate between natural and lab-grown stones, ensuring transparency for buyers. As the market fills with both product types, the ability of retailers to clearly label and explain the difference between the two has become essential for maintaining brand reputation and avoiding deceptive trade practices.
Challenges for Small and Medium Units
The dual pressure of falling export values and the need for new technology to process lab-grown diamonds is creating financial stress for many small and medium-sized units. These businesses, which are concentrated in manufacturing hubs like Surat and Mumbai, are finding it difficult to maintain profit margins. The rise of LGDs means that traditional diamond cutters and polishers must adapt their business models or risk falling behind. Many smaller firms are struggling with excess inventory and the financial strain caused by volatile global demand in key markets like the United States and China.
Looking ahead, the recovery of the diamond sector will depend on several factors. Investors and industry participants will likely monitor the stability of LGD pricing and whether the growth in synthetic diamonds translates into a permanent shift in consumer spending habits. The critical monitorable for the industry will be the ability of manufacturers to manage debt and operational costs in a market where the historical pricing power of natural diamonds is facing its toughest test in years.
