If you work in the jewelry crafts, particularly fine jewelry, you probably already know that the Gemological Institute of America (GIA) is the creator of the famous 4Cs (Color, Cut, Clarity and Carat weight), as well as the International Diamond Grading System™.
They have a ton of great info on their website about educating your customers about the 4Cs, which will help close your sales. Check out their iPad app, downloadable for free on iTunes.
Plus don't forget that GIA offers many fine classes and programs in this field. If you don't have the time to learn in one of their brick-and-mortar classrooms, they also have some great distance learning classes.
