Vision and Sustainability at the Core

The expansion reflects the founding vision of Vallabhbhai Lakhani, whose motto “Har ghar hira, har ghar Kira” encapsulates the dream of making diamonds accessible, sustainable, and globally trusted. Today, that vision has translated into a fully integrated company that manages every stage of the value chain—from diamond growing to cutting, polishing, and jewelry production—while employing over 10,000 artisans. Kira’s one-million-square-foot Surat facility is also notable for its sustainability efforts, powered by 75 MW of solar energy with plans to double that to 150 MW in the near future.

Global Reach and Trusted Partnerships

Kira serves more than 4,700 partners worldwide, including leading retail chains, jewelry designers, and manufacturers. With offices in Mumbai, Surat, Hong Kong, and New York, the company has become a reliable supplier of certified diamonds to some of the world’s biggest markets. Its U.S. operation, in particular, boasts the largest lab-grown diamond inventory in the country, with over 250,000 stones, including 150,000 available for next-day delivery.

Leadership Speaks on the Achievement

Rajesh Lakhani, Founding Partner of Kira Diam LLP, emphasized the importance of this milestone, stating, “Reaching 4,000 reactors is more than just a capacity target—it is a statement of India’s leadership in the global lab-grown diamond industry.” Similarly, Mehul Vaghani, CEO of Kira Jewels, highlighted the company’s approach: “This expansion is not just about growth, it’s about trust, responsibility, and ensuring the brilliance of lab-grown diamonds can be enjoyed worldwide.”

Future Outlook and Market Trends

With consumer demand for larger and more specialized lab-grown stones rising rapidly, Kira is positioning itself to meet evolving preferences. Current trends suggest strong momentum for elongated fancy shapes in the 3 to 6 carat range, reflecting shifting buyer desires in both retail and wholesale segments. By staying ahead of market shifts and investing heavily in sustainable energy and certified processes, the company continues to set new benchmarks for quality and scale.

Kira’s latest expansion reaffirms India’s pivotal role in the global diamond sector, combining heritage craftsmanship with modern technology. It signals that the future of the diamond market will not only be shaped by natural stones but also by sustainable, ethically produced lab-grown alternatives. This development underscores how innovation, tradition, and consumer trust can come together to redefine an industry.
