This article highlights the International Gemmological Institute’s robust financial results for Q4 and full-year 2025, marked by significant revenue and profit growth across all its core business segments.
The International Gemmological Institute (IGI) reported strong financial performance for the fourth quarter ended December 31, 2025, with operating revenue increasing by 21 percent to reach ₹319.70 crore. This growth was accompanied by a 26 percent increase in EBITDA, which reached ₹191.30 crore. Positive momentum was observed across all key business segments, including natural diamonds, lab-grown diamonds, jewelry, and gemstones, with certification revenue seeing a particularly strong year-on-year growth of 23 percent.
For the full year ending 2025, the company maintained its upward trajectory, recording a 17 percent increase in annual revenue and a 23 percent increase in EBITDA. Profitability margins also improved significantly; the EBITDA margin increased from 56.9 percent in the previous year to 59.9 percent, while the post-tax profit (PAT) margin reached 43.3 percent. The total consolidated PAT for the twelve months reached ₹531.60 crore, representing a 24 percent 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 capitalized on the growing global demand for lab-grown diamond (LGD) jewelry. The LGD segment benefited from stable wholesale prices over the past four quarters, encouraging broader consumer adoption. Entering the next year, the institution is focusing on leveraging its cross-segment presence and grading expertise to maintain its market position and enhance customer experience.
