The International Gemmological Institute (India) Limited (IGI) reported a robust financial performance for the fourth quarter ending December 31, 2025, marked by a 21 per cent increase in operational revenue to Rs 319.70 crore. This growth was mirrored by a 26 per cent rise in EBITDA, which reached Rs 191.30 crore. The positive momentum was visible across all primary business segments, including natural diamonds, lab-grown diamonds, jewellery and gemstones, with certification revenue specifically seeing a 23 per cent year-on-year boost.
For the full year ending December 2025, the company maintained its upward trajectory, recording a 17 per cent growth in annual revenue and a 23 per cent increase in EBITDA. Profitability margins also showed significant improvement; the EBITDA margin rose to 59.9 per cent from 56.9 per cent the previous year, while the Profit After Tax (PAT) margin climbed to 43.3 per cent. Total consolidated PAT for the twelve months reached Rs 531.60 crore, representing a 24 per cent increase compared to the 2024 calendar year.
Strategic advancements contributed heavily to these results, as IGI expanded its market share in natural diamond certification and capitalised on the rising global demand for lab-grown diamond (LGD) jewellery. The LGD sector benefited from stabilised wholesale prices over the last four quarters, encouraging broader consumer adoption. Moving into the next year, the institute remains focused on leveraging its cross-segment presence and grading expertise to sustain its market position and enhance customer experience.
