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.

- 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.

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.

Lost Florentine Diamond Resurfaces in Canada After a Century, Tracing Its Glittering Origins to India’s Golconda Mines
Once a royal treasure of the Medici and Habsburg dynasties, the 137.27-carat gemstone reemerges in a Montreal vault, reaffirming India’s Golconda as the cradle of the world’s most storied diamonds.
The legendary Florentine Diamond — a 137.27-carat light yellow gemstone believed to have originated from India’s famed Golconda mines — has been rediscovered in a Canadian bank vault, ending over a hundred years of intrigue surrounding its disappearance.
According to recent reports, the diamond—once among Europe’s most celebrated royal jewels—was located in a vault in Montreal, safeguarded for decades by descendants of the Austrian imperial Habsburg family. The gemstone vanished after the fall of the Austro-Hungarian Empire in 1918, following Emperor Charles I’s exile, sparking decades of speculation over its fate — whether it was stolen, lost, or secretly sold.



Historians now confirm that Empress Zita, widow of Charles I, discreetly transferred the diamond to Canada during World War II for safekeeping. Its authenticity was recently verified by a European jewellery house that historically served the Habsburg court, confirming the gem’s provenance and preservation.
Renowned for its pale yellow hue and unique double-rose cut with 126 facets, the Florentine Diamond boasts a storied history — from its origins in India’s Golconda mines, to the Medici treasury in Florence, and later as part of the Austrian Crown Jewels in Vienna.
Its rediscovery has reignited global fascination with India’s gem legacy, which gave birth to other iconic diamonds like the Koh-i-Noor, Hope, and Nassak. Experts say the find underscores the importance of provenance and gem heritage in an increasingly globalised jewellery market.
The Habsburg family has announced plans to publicly exhibit the diamond in Canada next year, with potential displays in Europe to follow.
After more than a century of obscurity, the reemergence of the Florentine Diamond not only restores a lost royal masterpiece but also revives India’s enduring connection to the world’s most illustrious jewels.
