Diamonds and colored gemstones are the jewelry industry’s heart and passion. If you want to work in this glamorous and fashionable world, you need to know them like you know your own name. GIA’s Graduate Gemologist Diploma Program provides you with the essential skills of any jewelry professional – how to grade and identify diamonds and colored gemstones.

You’ll learn proven techniques from the creators of the International Diamond Grading System. You’ll discover exactly how to determine a diamond’s quality and value. Once you know what to look for, and what to look out for, you can buy and sell diamonds with the insight of an experienced professional. With your grading and identification skills, you can walk into any gem dealer’s office on any continent and make profitable buying and selling decisions.

But diamonds are just the beautiful beginning. The jewelry industry is also about colored gemstones. In the colored stones and gem identification portion of this program, you take a wonderful journey into the mines, down supply chains, and onto the market. You learn how to look at a stone and judge its color, quality, and value. Practice that in class then employ it in the gem district of Bangkok, a tradeshow floor in Basel, or wherever your career and dream take you.
