The Four C's Of Diamonds  and Much More

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

DIAMOND GRADING CHART

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

​

After learning more, if you need to see diamonds in person, visit your local jewelry store. Get a better sense of what you personally value in a diamond. Note the color, cut, and clarity that best fit your needs. While you're there, compare the prices with what you find at Nishal Gems. We're confident you will be pleased with what you find.
