About the Company
International Gemological Institute Limited (NSE:IGIL; BSE Code: 544311) is a gemstone certification and jewellery authentication company headquartered in India. The company operates across three principal certification segments: natural diamonds, lab-grown diamonds, and coloured stone gemstones. IGIL provides independent third-party verification of stone origin, the four Cs (cut, colour, clarity, and carat), and increasingly traceability and provenance. The company operates through India-based operations and international subsidiaries spanning the United States, Belgium, Netherlands, and Italy. In early 2026, IGIL acquired American Gemological Laboratories (AGL), a US-based leader in gemstone certification, to expand its coloured stone capabilities and global footprint. The company reported a transition from calendar-year to financial-year reporting (ending March) during its recent earnings disclosures.
Announcement in Detail
IGIL's earnings call transcript for the quarter ended 30 June 2026 disclosed consolidated revenue from operations of INR 3,708 million, representing 23% year-on-year growth. Certification revenue specifically stood at INR 3,708 million, also growing 23% on a year-on-year basis. The company reported 3.56 million reports issued during the quarter, a 17% increase compared to 3.03 million in the same period of the prior year. Average selling price per report improved by 5% year-on-year to INR 1,010, with AGL consolidation contributing 3% of this gain and the base business contributing 2% through pricing stability. Management noted that pricing remained stable during the quarter.
Segment performance showed LGD certifications expanded 25% year-on-year, LGD jewellery grew 44%, and gemstones and other certifications surged over 200% largely on account of AGL's consolidation from the acquisition completed earlier in 2026. Excluding the AGL consolidation, the base business delivered 20% revenue growth for the quarter. EBITDA on a consolidated basis reached INR 2,238 million, reflecting 29% growth compared to the prior year, with AGL contributing an incremental 2% to EBITDA growth. EBITDA margins expanded 270 basis points to 60.4% for the quarter. Management attributed the sequential margin decline from Q4 FY26 to seasonality, noting that Q4 was characteristically stronger and the current quarter's margin performance represents a more sustainable run rate.
Profit After Tax on a consolidated basis reached INR 1,657 million, growing 31% year-on-year, with PAT margins at 44.7%, an improvement of 260 basis points. The company remains debt-free. Natural diamond loose stones grew 6% year-on-year while natural diamond jewellery expanded 2%, reflecting ongoing efforts to gain market share through new customer acquisitions and increased wallet share with existing clients. India standalone revenue reached INR 2,862 million, growing 22% year-on-year, with certification revenue of INR 2,792 million growing 22% supported by volume growth of 21%. India EBITDA was INR 1,970 million, up 15% year-on-year with margins at 68.8%.
Impact on Investors
The earnings call disclosures indicate accelerating revenue momentum driven by volume growth and pricing stability. Investors will note that the company has successfully integrated AGL into its consolidated results, with the acquisition contributing 3% to consolidated revenue growth and 2% to EBITDA growth during the quarter. The filing shows EBITDA margin expansion of 270 basis points on a consolidated basis, though management cautioned that the prior quarter benefited from seasonal strength. The disclosed sustainable EBITDA margin range and operating leverage expectations as volumes scale suggest the company is tracking towards full-year FY27 guidance, though specific margin guidance has not been quantified in the transcript.
Shareholders will observe that natural diamond segment growth of 6% in loose stones and 2% in jewellery remains below the company's overall growth trajectory, reflecting the segment's lower growth profile despite management's strategic prioritization. Management has articulated confidence in full-year natural diamond performance, citing ongoing customer acquisition and wallet expansion initiatives leveraging India-based strengths. The company's capital expenditure step-up and increased rental payouts on expanded office spaces support volume and business scale-up, though debt-free status remains intact. Investors tracking cash generation will need to monitor cash flow disclosures in subsequent quarterly filings to assess capex impact on free cash flow, as the earnings call transcript does not disclose cash flow metrics.
Sector and Market Context
The independent gemstone certification sector serves a foundational role in diamond and jewellery commerce by establishing standardized, objective assessment of stone quality and enabling efficient price discovery across the value chain. Lab-grown diamonds represent a structural growth driver for certification demand. According to industry data cited by the company, the rise of lab-grown diamonds has expanded rather than contracted the addressable market for certification, as increased market participants place greater emphasis on trust and commercial confidence to transact. Consumer preferences globally have evolved toward transparency, authenticity, contemporary design, and self-expression, trends that reinforce the value of independent third-party certification across both natural and lab-grown segments.
The gemstone certification sector benefits from ongoing consumer awareness campaigns, brand building investments, and geographic expansion into new markets. IGIL's geographic diversification through subsidiaries in Belgium, Netherlands, Italy, and the United States positions the company to serve global trade flows and consumer demand across regions. The company's strategic investments in artificial intelligence and machine learning to enhance service quality and turnaround times represent operational capabilities increasingly expected in the sector. Within India specifically, domestic market leverage and commission payouts to support geographic expansion reflect the company's strategy to deepen consumer awareness and retailer engagement within the primary market while developing international subsidiaries.
