Mumbai: India’s lab-grown diamond jewellery segment is finding a stronger foothold in the US, with Goldiam International securing a Rs 60-crore export order from international clients in the market. The order is slated for execution by December 31, 2026, and comes shortly after the company announced a Rs 50-crore export order in August.
The US remains a significant market for lab-grown diamonds, particularly in bridal jewellery. Data from BriteCo cited in the report shows that lab-grown stones accounted for 51% of newly appraised engagement-ring centre stones in the first half of 2026, compared with 47% in 2025.
The category is also extending beyond engagement rings, with consumers increasingly considering lab-grown diamonds for earrings, pendants, bracelets and other jewellery.
For Indian companies, the opportunity is evolving from supplying polished stones to manufacturing finished lab-grown diamond jewellery for overseas consumers.
Goldiam’s latest order reflects this shift, combining India’s manufacturing capabilities with growing acceptance of the category in the US. The model could open further avenues for Indian jewellery manufacturers supplying international brands and retailers.
India is also investing in the technology required to support the sector. The government’s five-year R&D initiative for lab-grown diamonds aims to develop domestic capabilities for producing LGD seeds and manufacturing equipment.
As part of this push, the India Centre for Lab Grown Diamond (InCent-LGD) at IIT Madras was established with an approved outlay of Rs 242.96 crore over five years.
With overseas orders increasing and domestic technological capabilities being developed, India is positioning itself not just as a producer of lab-grown diamonds, but as a potential global hub for LGD jewellery manufacturing.
