IGI reports a 17 % increase in revenue for 2024; 29 % growth in profit
The International Gemological Institute (IGI), a leading grading company in the lab-grown diamond market, has reported record financial performance for the calendar year (CY) 2024. The company achieved a 17% increase in revenue and a remarkable 29% growth in profit, driven largely by its dominant 65% share of the global lab-grown diamond grading market.
- Revenue: $120.8 million (INR 10.53 billion), marking a 17% increase compared to the previous year.
- Profit After Tax: $49 million (INR 4.27 billion), reflecting a substantial 29% year-over-year growth.
- Market Share: IGI continues to dominate the lab-grown diamond grading market with a 65% global share.
IGI’s strong financial performance has been supported by its market leadership and strategic business decisions. The company went public in December 2023 with an initial public offering (IPO) that valued IGI at $3.5 billion. This marked a significant valuation jump from its $570 million acquisition price when Blackstone, the world’s largest alternative asset manager, took ownership in May 2023.
Eashwar Iyer, IGI’s Global Chief Financial Officer (CFO), emphasized the company’s operational strength and strategic execution, attributing the record revenue and profit growth to IGI’s ability to capitalize on market opportunities and strengthen its competitive position.
IGI’s robust financial performance underscores the expanding demand for lab-grown diamonds and the growing importance of reliable certification in the industry. The company’s continued leadership in this segment reinforces its credibility and positions it for sustained growth in the future.
IGI’s record-breaking financial results in 2024 highlight its dominant market position, successful strategic initiatives, and ability to drive profitability. With a strong financial foundation and continued expansion, IGI remains at the forefront of the lab-grown diamond grading industry, setting benchmarks for excellence and growth.

Motorsport Meets High Jewellery: Hannah St John Turns Heads with ‘La Velocita’ Diamond Necklace at F1 Event
A 25-carat, 1,800-diamond Masterpiece Inspired by Formula 1 circuits Takes Centre Stage at the Glamour on the Grid ahead of the Australian Grand Prix
At the glamorous lead-up to the Australian Grand Prix, Hannah St John, partner of Liam Lawson, made a striking statement at the Glamour on the Grid event with a one-of-a-kind diamond necklace that seamlessly blended motorsport and haute jewellery.
Titled “La Velocit” (The Speed), the necklace was crafted by Australian atelier Martin Rogers Jewellery. The extraordinary piece features approximately 1,800 diamonds totalling 25 carats, intricately arranged to trace the outlines of iconic Formula 1 circuits from the global racing calendar.



A true testament to craftsmanship, the necklace required an estimated 250–300 hours of meticulous handwork, including weeks dedicated solely to precision diamond setting. Valued at around AUD $500,000 (approximately $350,000 USD), the piece stands as a bold fusion of speed, design, and luxury artistry.
Blurring the lines between engineering inspiration and fine jewellery, “La Velocità” captured attention across the paddock, proving that Formula 1’s influence extends far beyond the track.
