The Gemological Institute of America, GIA, is the world’s foremost authority on diamonds. In the 1940s, GIA established the “4Cs” and the International Diamond Grading System™ – to this day, the worldwide standard for evaluating diamond quality.
We would be happy to educate you in person on the “4Cs” when you visit our store. In the meantime you can get started by watching this video to prepare you to select your perfect diamond.
Hope to see you soon to answer your questions!
