Jewelbox

Jewelbox is a direct-to-consumer brand specializing in certified lab-grown diamond jewelry. Founded in May 2022 by siblings Vidita Kochar Jain and Nipun Kochar, the Kolkata-based company operates on a 'phygital' model, integrating online sales with physical retail stores. The company was started after Vidita's personal experience with a lab-grown diamond engagement ring sparked the idea to create a brand focused on accessible and sustainable luxury.

The founders, both qualified Chartered Accountants, ventured into entrepreneurship without a family background in the jewelry industry. Nipun Kochar previously co-founded an AdTech startup, Planmyad, before shifting his focus to the lab-grown diamond market. Vidita Kochar Jain holds an MBA from the Indian School of Business and gained corporate experience at Swiggy before launching Jewelbox with her brother. Their lack of traditional jewelry experience allowed them to approach the market with a consumer-focused mindset, emphasizing trust and transparency.

Jewelbox offers a wide range of jewelry, including rings, bracelets, earrings, and pendants, made with diamonds that are chemically, physically, and optically identical to mined diamonds. These lab-created diamonds are priced significantly lower than their natural counterparts, making diamond jewelry accessible to a broader market. All diamonds are certified by recognized gemological labs like IGI and GIA, and the jewelry is hallmarked to ensure quality and authenticity. The business model includes an 80% buyback policy and 100% exchange benefits. The company has a robust in-house design team that launches hundreds of new designs monthly and offers customization services, delivering bespoke pieces in approximately three weeks.

The startup has shown significant growth, reporting a revenue of ₹14.3 Cr for the fiscal year ending March 2024, a substantial increase from the previous year. Jewelbox has successfully raised capital to fuel its expansion, including a pre-Series A round of $3.2 million in April 2025. The company operates eight stores across cities like Delhi, Bengaluru, and Chennai and plans to expand its retail footprint to 30 stores. It also serves international customers through direct shipping.
