India’s Lab-Grown Diamond Exports Reach Record High in 2025
India Strengthens Its Global Leadership in Lab-Grown Diamonds
India’s lab-grown diamond (LGD) industry has achieved a significant milestone in 2025, with exports reaching a record high. This achievement reinforces India’s position as the world’s leading producer and exporter of lab-created diamonds.
Driven by rising global demand, technological innovation, and the increasing acceptance of sustainable luxury, India’s LGD sector continues to play a pivotal role in shaping the future of the international jewellery market.
Technology and Sustainability at the Core

The surge in exports reflects the growing adoption of advanced technologies such as CVD and HPHT, which enable the production of high-quality, precision-grown diamonds that match natural diamonds in brilliance and clarity.
Manufacturers are increasingly prioritizing sustainability and traceability, adopting energy-efficient, carbon-neutral processes that align with global environmental standards. This shift toward ethical production is helping India meet the expectations of a new generation of conscious consumers and international luxury brands.
Evolving Consumer Preferences Fuel Growth

Consumer perception of lab-grown diamonds has undergone a transformation. Millennial and Gen Z buyers are driving this change, valuing affordability, sustainability, and innovation over traditional notions of rarity.
Global jewellery retailers have responded by launching dedicated lab-grown diamond collections, leading to steady demand growth in markets across the United States, Europe, and the Middle East. This momentum has boosted India’s exports of both loose LGDs and finished jewellery, expanding the country’s footprint in the premium jewellery segment.
Future Outlook: Sustainable Growth Ahead

Industry forecasts indicate that India’s lab-grown diamond exports will continue to grow at an annual rate of 15–20% over the next few years. With its blend of cutting-edge technology, skilled craftsmanship, and global partnerships, India is poised to remain at the forefront of this evolving sector.
As the global jewellery industry embraces sustainability and transparency, India’s lab-grown diamond sector stands as a symbol of innovation, responsibility, and craftsmanship—a true bridge between tradition and technology, defining the future of ethical luxury.

The Role Of Hallmarking and Transparency In Strengthening Consumer Confidence
By Suresh Krishnan, Vice President – Sales, PNG Jewellers
In India, jewellery is equally an emotional purchase and a significant financial transaction. As consumers become more informed and digitally empowered, trust is increasingly becoming a decisive factor alongside design, price and brand reputation. Hallmarking has played an important role in creating that trust by giving consumers third-party assurance of precious-metal purity.

India’s hallmarking ecosystem has expanded significantly. BIS data shows that hallmarking registrations increased from 34,647 to 1,37,315 between April 2021 and March 2022 *1, while more than 8.72 crore gold and silver articles were hallmarked during that year. The introduction of the six-digit Hallmark Unique Identification (HUID) in 2021 has further strengthened traceability. Consumers can verify a gold article’s HUID through the BIS CARE app, adding an independent layer of assurance at the point of purchase.
For an organised retailer, this becomes particularly relevant as jewellery discovery increasingly moves online. A customer may discover a product on social media, compare it on an e-commerce platform and complete the transaction digitally. In such a journey, hallmarking helps bridge the trust gap created by the absence of physical touch and feel. When purity is independently verifiable, consumers can make online purchases with greater confidence.
The opportunity is also expanding beyond gold. BIS has brought both gold and silver under its hallmarking framework. In FY2024-25, more than 32 lakh silver jewellery articles*2 were hallmarked. The revised IS 2112:2025 introduced HUID-based hallmarking for silver on a voluntary basis from September 2025, creating greater traceability and consumer assurance in a category that is increasingly relevant to younger and value-conscious buyers.
This evolution matters commercially. KPMG’s India CX Report 2025*3 found that 27% of fine-jewellery customers are more confident in authenticity, quality and value when they trust a brand, while 9% said they would explore another brand if jewellery appeared overpriced for its quality. These findings underline why trust is not simply a compliance issue; it directly influences consideration and willingness to pay.
Contributing to the larger goal of organised and transparent trade, hallmarking has now been integrated as part of the broader customer experience across stores, CRM and e-commerce. As India’s jewellery market becomes increasingly omnichannel, the brands that communicate purity, pricing and policies clearly will be better positioned to convert digital discovery into purchase and, more importantly, build relationships that extend beyond a single transaction. The future of jewellery retail will therefore be defined not only by what consumers see, but by how confidently they can verify what they are buying and hallmarking takes care of that concern efficiently.
