D2C lab-grown diamond jewellery brand Cosmos Diamonds is accelerating its retail expansion while strengthening its long-term growth strategy. The company aims to achieve Rs 55 crore in revenue in FY27 and Rs 100 crore in annual recurring revenue (ARR) by the end of 2027 as India’s lab-grown diamond jewellery market continues to gain momentum.
Founded by Sanjana Tripuramallu in 2021, Cosmos Diamonds focuses on transparent business practices, heritage-inspired jewellery collections, and a 100 percent buyback policy to differentiate itself in the fast-growing segment.
The company reported Rs 20 crore in revenue in FY26, more than doubling its Rs 9.77 crore revenue recorded in FY25. Additionally, it is currently operating at an ARR of nearly Rs 30 crore, reflecting strong business momentum.
Before launching the brand, Tripuramallu conducted extensive market research by interacting with more than 1,000 women to understand their jewellery purchasing preferences. The research revealed that Indian consumers preferred heritage-inspired jewellery over minimalist designs while also seeking stronger financial assurance after making a purchase.
Based on these insights, Cosmos Diamonds introduced traditional Indian-inspired jewellery collections backed by a contractual 100 percent buyback programme. The policy allows customers to choose either a cash refund or store credit, thereby addressing one of the biggest concerns associated with lab-grown diamonds by providing greater confidence in their long-term value.
Currently, Cosmos Diamonds operates flagship stores in Bengaluru and Vijayawada, where it has achieved an in-store conversion rate of 55 percent and a repeat customer rate of 40 percent.
Furthermore, the company plans to expand its retail footprint to five stores by the end of 2027 by opening new outlets in Hyderabad, Visakhapatnam, and Chennai.
Meanwhile, Cosmos Diamonds continues to pursue its growth strategy without raising external capital. The company stated that each new store must achieve sustainable profitability before further expansion, reinforcing its disciplined and bootstrapped business model.
