Ratings and Reviews
In the market for a diamond?
GIA is for sure the global authority in grading diamonds. This is a great resource tool to use if you're in the market to get yourself or loved one a beautiful diamond!
Nice app, please update for iOS 11. Thanks so much for making this!
Excellent explanation of diamond grades!
I saw this at the Atlanta Jewelry Show this weekend and thought it to be the best tool I have ever seen to show a customer what different characteristics of a diamond are considered in the grading of that diamond. Thank you, GIA!
