International Gemmological Institute (India) Ltd – The Diamond Grader IPO That Sparkles with 68% ROCE
1. At a Glance
From Antwerp to Andheri, IGI has become the gold standard (well, diamond standard) for grading everything shiny. With 59% of revenue from lab-grown diamonds, 54% ROE, and an IPO that fetched ₹4,225 Cr in Dec’24, IGI India is the CA who certifies diamonds instead of balance sheets. Only catch? The stock trades at 13x book value, proving that even valuation multiples can glitter.
2. Introduction
Remember when every Indian mom told you, “Beta, diamonds are forever”? IGI decided to make that literal—by grading, certifying, and stamping their existence into Excel sheets.
Born in Belgium, IGI grew into a 31-branch empire across 10 countries with schools of gemology sprinkled across six more. In India, they’ve embedded themselves in Surat and Mumbai like gold chains in a wedding guest list.
Their services? Certifying natural diamonds, blessing lab-grown ones (aka diamonds made in microwave 2.0), grading jewelry craftsmanship, and teaching gemology to the next generation of diamond nerds. Client list includes 7,500+ wholesalers, jewelers, and retailers—from mom-and-pop Surat cutters to international luxury brands.
And investors? They got a taste of sparkle when IGI IPO’d in Dec 2024, raising ₹4,225 Cr. The market response? Almost as enthusiastic as a Bigg Boss eviction episode.
3. Business Model – WTF Do They Even Do?
Think of IGI as the CBSE board examiner of diamonds.
Diamond Grading (4Cs): Cut, clarity, color, carat. One mistake and you’ll be explaining why “slightly yellow” is actually “warm champagne.”
Lab-Grown Diamonds (59% revenue): The Tesla of diamonds—made in labs, cheaper, cleaner, and the biggest revenue engine for IGI.
Jewelry & Colored Stones (20%): Emeralds, rubies, sapphires. Basically, everything you see in a Karan Johar film set.
Education (1%): IGI runs 18 gemology schools. Low revenue, but great PR—keeps the pipeline of diamond geeks flowing.
Upcoming? A 214,000 sq. ft. Surat lab—because if you want to rule the world’s diamond polishing capital, you better have lab space bigger than an IPL stadium lounge.

Commentary: Revenue steady, margins fatter than a Diwali gift box. PAT growth is sparkling, though sequential dip shows certification cycles aren’t linear.
