India’s lab-grown diamond market makes the cut as investor interest surges in 2025

Actor Shilpa Shetty-backed Limelight, which is in talks to raise its second round of capital this year, joins the growing list of other small brands such as Onya, Giva, Jewelbox, Lucira Jewellery and Aukera, among others, who have snagged monies in recent months. Limelight has appointed Ambit Capital to raise about $20 million to fund its expansion plans, two people familiar with the matter said.

Confirming the fundraise, the six-year-old company’s co-founder Pooja Madhavan said the funds will be used towards store expansion and brand building as it looks to touch 100 stores over the next year. “We are in final talks with growth PE funds and reputed family offices (for the fundraise)," she told Mint.

Other similar fundraises include Onya’s ₹5.5 crore in a pre-seed round led by Zeropearl VC last week, Aukera’s $15 million raise led by Peak XV Partners and Aditya Birla Ventures-backed Giva raised ₹530 crore in an internal round led by Premji Invest, Epiq Capital and Edelweiss Discovery Fund, as it looks to scale up its lab-grown diamond offerings.

Nine pure-play lab grown diamond startups collectively raised a record $26.4 million in 2025, compared with $4.7 million across eight startups last year, data from market intelligence provider Tracxn showed.

The development comes as India’s lab-grown diamond jewellery market, valued at about $300-350 million in 2024, expects to grow at a CAGR of 15% over the next decade, as per consultancy firm Redseer’s estimates. As the market evolves, several prominent jewellery brands will gradually pivot from exclusively natural/mined diamonds in favour of lab-grown alternatives, alongside high-end jewellers incorporating the lab-growns into their select collections, which will drive sales volumes and act as an affordable entry point for consumers.

This segment has particularly picked pace in the last five years, with millennials and gen Z leading this shift, driven by better value, trendier designs from new-age brands, and growing comfort with lab-grown diamonds as a certified, high-quality product. This category has also widened beyond occasional fashion to gifting, dailywear, and increasingly bridal, reflecting sustained consumer confidence and a willingness to treat them as a mainstream jewellery option, Rohan Agarwal, partner at Redseer told Mint in an emailed statement.

He further added that new-age brands have steadily gained market share in the mid-ticket gifting and daily wear segment with many trying to push into premium ranges. While the competitive landscape is still evolving, incumbents have already started responding by launching LGD lines of their own, although the extent to which they can challenge remains to be seen.

Major Indian brands that are considering a foray into this category include Malabar Gold & Diamonds, Senco Gold, which has launched the sub-brand Sennes and Tata’s Trent, which launched its brand Pome in Westside stores.

Devangshu Dutta, founder and chief executive officer at Delhi-based consulting firm Third Eyesight, echoed the sentiment. He explained that new-age lab grown diamond players are forcing traditional jewellers to introduce LGD options or risk losing younger customers. “Not just precious jewellery brands, even those that started as fashion jewellery are expanding their range with LGD designs."

“Down the road, there is potentially scope for consolidation as investors tend to prefer a handful of scaled platforms with strong brand recall and robust economics. So, as the category matures, there may be strategic acquisitions by large jewellery houses and corporates, as well as mergers among funded startups," he added.

Those startups that can combine in-house manufacturing, design capabilities and data-driven retail expansion would be at an advantage, Dutta said. “Key future growth areas for LGD startups include omnichannel retail presence within India, with offline stores especially in demand-dense locations such as the metros and Tier 1 cities, export markets both with potential cost advantages and brand expansion, and extending into fashion jewellery, everyday wear, coloured lab grown stones and even luxury collaborations that position lab grown as aspirational rather than merely budget friendly."

Limelight’s Madhavan added that factors, including pricing stability, overall market growth, and changing consumer preferences have contributed to the promising outlook for this sector. With LGD prices stabilizing with an increase of 25% in the last year and mined diamonds declining by 3%, this has further built confidence in the sector, she said.

“LGDs cost less (to an extent) and are not tied to legacy mining constraints, brands are able to experiment more with design, carat sizes, cuts, shapes, which adds to the growth story," she said, adding that the market is at an inflection point with LGD far outpacing the traditional diamond jewelry market that is growing at low single-digits.
