Revolutionizing Luxury: Rupesh Jain to launch Lab-Grown Diamond Collection Brand
Rupesh Jain, the founder of Candere by Kalyan Jewellers, is making a return to the jewellery industry with a new venture focused on lab-grown diamonds (LGDs). After successfully scaling Candere, an online jewellery brand he founded in 2013, Jain sold the company to Kalyan Jewellers in a phased acquisition, with the final stake transfer completed in 2024. Now, he is betting on LGDs as the next big shift in the luxury jewellery market, launching his new brand this April during Akshaya Tritiya.
Lab-grown diamonds have been gaining global traction, and in India, the category is still in its early stages but is witnessing significant momentum. Companies like Giva, Avira Diamonds, and Fiona Diamonds have entered the space. Last month, Priyanka Gill, seasoned entrepreneur and co-founder of Good Glamm Group, announced the launch of her lab-grown diamond venture, Coluxe.
Comparing the prices of LGDs with natural diamonds, Jain explained, “A natural diamond priced at Rs 100, an equivalent LGD costs just Rs 20-25, making high-quality solitaires accessible to a much larger consumer base.”
Highlighting the massive opportunity in the LGD segment, driven by Gen Z and millennial consumers, Jain said that he aims to position the new venture as a premium yet accessible brand. “We aim to offer product quality comparable to global luxury houses like Cartier and Tiffany, but at a more competitive price,” he commented.
The company will follow an online-first model before expanding into offline retail. The startup is currently bootstrapped, with Jain focusing on assembling a strong team, including senior hires for merchandising and a tech agency to drive digital expansion. Internationally, the demand for LGDs is already established, and Jain believes India is well-positioned to become a major supplier and brand builder in this space, thanks to government support, manufacturing ecosystem, and government backing.

Richemont and Signet Jewelers Could Join Global Diamond Consortium In Bid For De Beers
Richemont, Signet Would Connect The Consortium To Key Global Growth Vectors Spanning Luxury High Jewelry and Mass-Market Retail.
The Global Diamond Consortium (GDC)
Richemont and Signet Jewelers are reported to be in talks about joining the Global Diamond Consortium (GDC), the preferred bidder for De Beers according to a Bloomberg News report.
​GDC was selected in July 2026 as one of Anglo American’s preferred bidders for De Beers as part of Anglo American’s ongoing corporate restructuring.
​The potential inclusion of Richemont—owner of luxury Maisons including Cartier and Van Cleef & Arpels—and Signet Jewelers—the world’s largest retailer of diamond jewelry, operating brands such as Kay Jewelers, Zales, and Jared—would connect the consortium to key global growth vectors spanning luxury high jewelry and mass-market retail.
​Strengthening the Natural Diamond Ecosystem: Participation by major luxury brands and global retail leaders reinforces commitment across the entire value chain—from responsible mining and manufacturing to consumer engagement.
​Balanced Governance Structure: Discussions center on potential minority equity positions that would support long-term category growth while maintaining appropriate separation between ownership and commercial strategy.
​Broad Stakeholder Participation: The consortium continues to advance talks with host governments, including discussions with the Government of Botswana regarding a potential increase in its equity share in De Beers from 15% to approximately 25%, alongside participation from private investors and southern African host nations.
​​Discussions between GDC, Richemont, Signet, and participating government stakeholders remain ongoing. Terms of any potential participation, including the size of equity interests, have not been finalized and remain subject to regulatory approvals and definitive documentation.
