Lab-grown diamond jewellery startup Ethera has raised Rs 25 crore in fresh funding from jewellery retailer BlueStone, which has increased its strategic investment in the brand.

The capital infusion is expected to support Ethera’s next phase of expansion, with a focus on strengthening its physical retail presence and scaling omnichannel operations. The company currently operates exclusive brand outlets in Bengaluru and New Delhi and plans to expand into additional metro markets.

Founded as a design-forward lab-grown diamond jewellery brand, Ethera offers contemporary collections featuring IGI-certified lab-grown diamonds set in BIS-hallmarked gold. The company introduces new designs on a regular basis, targeting digitally aware and value-conscious consumers seeking certified and sustainably positioned alternatives.

The latest investment underlines growing retailer and investor confidence in India’s emerging lab-grown diamond jewellery segment. For BlueStone, the funding aligns with its broader strategy of expanding exposure to high-growth categories within the organised jewellery retail space.

Industry observers note that strategic partnerships between established retailers and specialised lab-grown brands could accelerate category adoption, drive standardisation, and strengthen supply chain efficiencies across the value chain.

The development reflects sustained momentum in the lab-grown diamond segment as brands scale store networks while balancing online and offline distribution channels.
