Careful analysis by IGA Labs professionals

Analysis & Grading

by the 4C's standards 

Jewelry professionals use a systematic way to evaluate and discuss diamond's various internal characteristics. Otherwise, there would be no way to compare one diamond to another. And there would be no way to evaluate and discuss the qualities of an individual diamond. Diamond professionals use the grading system which established the use of four important factors to describe and classify diamonds: Clarity, Color, Cut, and Carat Weight.
