Rough Diamond Evaluation In-Person Course
In two days, you’ll learn to read diamonds the way geologists read stone — not as products, but as three-billion-year-old stories waiting to be told.
One wrong judgment on color or a missed inclusion can be the difference between a massive profit and a devastating loss. Whether you are an investor, a jeweler, or an aspiring dealer, you cannot afford to play a guessing game.
At Corlia Roberts Diamond Education, we take the mystery out of the rough. We don’t just teach theory; we give you the ‘eyes’ of an expert so you can walk into any deal knowing exactly what the stone is worth.
Designed for beginners and professionals alike, this intensive hands-on program takes you through the entire diamond value chain—from the geological formation of diamonds to evaluating and pricing diamond parcels in real-world scenarios.
Each session is packed with expert knowledge, practical exercises with real rough diamonds, and personalized guidance—so you can master rough diamond evaluation through direct experience. Plus, gain lifetime access to our Digital Campus and earn an internationally recognized certificate.
