International Gemological Institute Limited (IGI) reported 21% year-on-year growth in both revenue and EBITDA for the quarter ended March 2026, supported by growth across its natural diamond, laboratory-grown diamond and laboratory-grown diamond jewellery segments.

The company reported consolidated revenue from operations of Rs 3,686 million for the Jan-Mar 2026 quarter, compared to Rs 3,048 million in the corresponding period last year. EBITDA for the quarter stood at Rs 2,360 million against Rs 1,958 million a year earlier. Profit after tax (PAT) rose 28% year-on-year to Rs 1,796 million.

IGI stated that it has transitioned its financial reporting structure from a calendar year to a financial year ending March. As a result, the current reporting period includes a 15-month period ending March 31, 2026. For the 15-month period from Jan 2025 to Mar 2026, the company recorded revenue of Rs 15,976 million, up 18% year-on-year.

Tehmasp Printer, Managing Director and CEO of IGI, said, “During the quarter, we completed the acquisition of AGL, marking an important strategic milestone in IGI’s growth journey. The acquisition strengthens our global footprint, enhances our capabilities within the high-potential colored stone certification segment, and further diversifies our service portfolio beyond diamonds. The company sees strong synergistic potential through operational integration, complementary client relationships, cross-selling opportunities, and deeper engagement across the value chain.”

Printer also said, "IGI is continuing to integrate AI and machine learning into operations to improve service quality, turnaround times and operational efficiencies." According to the company, rising disposable incomes, increasing consumer demand for certified jewellery and the growing adoption of laboratory-grown diamonds are contributing to changes in the global jewellery and diamond market. IGI noted that demand for certified diamonds, gemstones and jewellery is expanding beyond traditional markets, increasing the need for transparency and authentication services. IGI currently operates 36 laboratories and 21 Schools of Gemology across 10 countries.
