Why It Matters

The infusion accelerates Ethera’s push into physical retail, positioning it to capture growing consumer demand for sustainable lab‑grown diamonds in India. It also signals BlueStone’s confidence in the premium lab‑grown segment, potentially reshaping the Indian jewellery market.

Key Takeaways

• Ethera raised Rs 25 crore from BlueStone.
• Funding doubles BlueStone’s stake, enabling retail expansion.
• Five stores now in Bengaluru and Delhi, more launching soon.
• Plans to boost design, tech, and brand for omnichannel growth.
• Launches 200+ new designs monthly using IGI‑certified diamonds.

Pulse Analysis

India’s lab‑grown diamond market is gaining momentum as consumers seek ethically sourced luxury at lower price points. Sustainability concerns, coupled with advances in high‑pressure high‑temperature (HPHT) and chemical vapor deposition (CVD) technologies, have driven a double‑digit annual growth rate for synthetic gemstones. Retailers are capitalising on this trend by integrating online convenience with tactile in‑store experiences, a model that resonates with a younger, digitally native demographic.

Ethera’s latest funding round underscores the strategic importance of an omnichannel approach. By leveraging BlueStone’s capital, Ethera plans to expand its brick‑and‑mortar footprint beyond Bengaluru and New Delhi, targeting tier‑1 and tier‑2 cities where affluent shoppers still value physical interaction with high‑value jewellery. The infusion will also enhance its design pipeline and technology stack, enabling rapid rollout of over 200 new collections each month while maintaining IGI certification and BIS‑hallmarked gold standards.

The partnership signals a broader shift in the Indian jewellery ecosystem, where traditional gold‑centric players are increasingly eyeing synthetic alternatives. BlueStone’s deeper stake suggests confidence that lab‑grown diamonds can deliver higher margins and faster inventory turnover compared with mined stones. As more startups adopt similar funding models, the competitive landscape is set to evolve, prompting legacy jewellers to either acquire innovative brands or develop their own sustainable lines to stay relevant in a market that values both authenticity and environmental responsibility.
