About Us: The New Era of Diamond Excellence
Welcome to DiamGold Academy, the world’s premier destination for diamond education and professional mastery.
Born from a strategic amalgamation of three industry titans—the Corlia Roberts Institute of Diamonds, CXD Diamonds, and the original DiamGold expertise—we have united under the DiamGold.org banner to create a singular, powerhouse institution.
By combining our heritage, specialized technical resources, and global networks, we offer an unparalleled educational experience that bridges the gap between raw potential and market-leading expertise.
Our Heritage, Your Advantage
The strength of DiamGold Academy lies in the legendary foundations of our founding partners:
- The Corlia Roberts Institute of Diamonds: Bringing decades of world-class pedagogy and a reputation for nurturing the industry’s most successful diamond graders and entrepreneurs.
- CXD Diamonds: Providing deep-rooted technical precision, market-ready valuation strategies, and a frontline understanding of the global diamond trade.
- DiamGold: Contributing the innovative vision and rough diamond mastery that defines our modern curriculum.
Why This Amalgamation Matters
In a rapidly evolving global market, “good enough” knowledge is a liability. By joining forces, we have consolidated our assets to provide students with:
- Combined Expertise: Access to a faculty of master graders, gemologists, and market analysts who have shaped the industry for over 30 years.
- Expanded Resources: More rough specimens, more advanced technology, and a broader curriculum that covers everything from mine-to-market.
- Global Networking: A unified alumni network that spans continents, providing our graduates with immediate professional credibility and connections.
Our Mission
“To empower the next generation of diamond professionals with the precision of science and the intuition of the master craftsman.”
At DiamGold Academy, we don’t just teach you how to look at a diamond; we teach you how to see its future. Whether you are a newcomer seeking a career or a seasoned professional refining your edge, our integrated school provides the most comprehensive certification in Rough Diamond Grading, Evaluation, and Polished Valuation available today.
Leading the Industry into the Future
