International Gemmological Institute (India) Ltd Q3FY26 – Diamonds, Drama, and ₹1,298 Crore Profits Sparkle Brighter Than Any Solitaire
1. At a Glance
If bling had a balance sheet, it would look exactly like International Gemmological Institute (India) Ltd (IGIL). With a market cap of ₹14,484 crore, this newly listed diamond certification giant has become the gold standard (well, diamond standard) for authenticity in both natural and lab-grown jewels. The stock trades at ₹335, down from its 52-week high of ₹642 — apparently, even gems need polishing in the market.
In Q3FY26, the company dazzled with ₹3,037 million in revenue, ₹1,763 million EBITDA, and ₹1,298 million PAT, showing a 21% YoY revenue surge and maintaining its “our margins shine brighter than your ex’s engagement ring” consistency. At a jaw-dropping ROE of 54.4% and ROCE of 68%, IGIL seems to have cracked the formula for turning carats into crores.
But wait — this isn’t your usual jewellery maker story. IGIL doesn’t make diamonds; it judges them. Yes, it’s that classy auditor everyone fears — the one who tells a billionaire’s fiancée her diamond’s worth less than her handbag.
2. Introduction – The Jewel Inspector General
Welcome to the world where sparkle meets science, and emotions get certified by microscope-toting gemologists. International Gemmological Institute (India) Ltd, or IGIL for the serious ones, is the world’s largest independent certification authority for diamonds, gemstones, and jewellery.
Born in Belgium and now headquartered in India’s sparkle capital (Surat and Mumbai), IGIL is that global teacher who grades every diamond’s report card — cut, color, clarity, and carat. If your stone doesn’t pass IGI’s test, it’s just glorified glass.
After its blockbuster ₹4,225 crore IPO in December 2024, the company became the most fashionable nerd in the market — a blend of data, grading, and glamour. With operations across 10 countries, 31 labs, and 18 gemology schools, IGIL practically runs the Harvard of diamond science.
And the numbers? Even better than its polishing skills. FY24 saw revenue of ₹1,174 crore and net profit of ₹511 crore, translating to a whopping 59% operating margin. In an era where most companies brag about single-digit OPM, IGIL operates like a monopoly in sparkle validation.
3. Business Model – WTF Do They Even Do?
Let’s decode this glittery business. IGIL doesn’t sell jewellery. It sells trust. And that trust costs crores.
The company provides certification and accreditation for diamonds — both natural and lab-grown — along with coloured stones and jewellery pieces. It’s like the CA firm of the gem world, but instead of auditing accounts, it audits brilliance.
Its major services include:
Diamond grading: Determining the 4Cs (cut, color, clarity, carat) for both mined and lab-grown diamonds.
Gemstone verification: Evaluating rubies, sapphires, emeralds, and more for authenticity and quality.
Jewellery assessment: Checking craftsmanship, symmetry, and stone mounting quality — basically, rating jewellery like food critics rate biryani.
Education: Through 18 IGI Schools of Gemology in six countries, the company trains the next generation of sparkle detectives.
And the fun fact? IGIL earns ~59% of its revenue from lab-grown diamonds, 19% from natural diamonds, and 20% from jewellery and colored stones. Education and events make up the rest — because why not add a seminar on how to spot fakes at parties?
Their upcoming 214,000 sq ft Surat facility promises to make even Reliance’s diamond building look underdressed.

💎 Commentary: IGIL’s earnings are so consistent they could give HDFC Bank’s accounting team FOMO. The company’s QoQ growth may look tame, but margins above 58% are a flex most
