DIAMOND EDUCATION

Buying a diamond does not have to be an uncomfortable experience. The IDR Education Guide is designed to give you the tools and information you need to properly evaluate diamond quality and value with confidence.

There are a variety of factors which affect the price of a diamond. Focus on those factors most important to you, and choose a diamond that satisfies your individual standards.

Every diamond certified by the IDR undergoes a thorough, independent evaluation. Here you will learn how IDR diamond grades are established, and how those grades affect the diamond's price. Each of the main C's (Carat Weight, Cut, Color, Clarity) is accompanied by a diamond chart illustrating the differences between grades.
