Our certified gemologists use special care in examining each individual diamond, whether it is colorless or fancy color—from the smallest size to the largest most valuable diamond.

Every diamond is evaluated for key characteristics that provide our clients with the most accurate diamond grading possible.

Analysis & Grading

by the 4C's standarts 

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.
