Buying A Diamond in Kansas City- Diamond Cut Grade

Sparkle, Brilliance, Fire, Scintillation - Words that should describe your diamond.

When purchasing a loose diamond for an engagement ring or other special piece of jewelry it is important to have an understanding of the qualities of diamonds that make them so valuable.

In the early 1950s the Gemological Institute of America (GIA) established a grading system for diamonds which was adopted by the international jewelery community.  This diamond grading system is based on four characteristics that every diamond exhibits. It is the combination of these characteristics that makes each diamond unique. These four characteristics are: Cut, Color, Clarity, and Carat weight. 

The GIA has an educational division for people interested in becoming Graduate Gemologist. A Graduate Gemologist is specially educated to be an expert in all aspect of diamonds. 

The GIA also has a division that grades diamonds in their laboratories in California and New York. When a diamond report is issued it tells about each aspect of the stone based on GIA standards. This report increases the value of the diamond and assures you of its quality.  

When shopping for a diamond cut is the most important of the 4 Cs.


There are two aspects in regards to cut.

1. The shape of the stone (round, princess cut, marquise, pear, radiant, etc.) you want.

2. How the stone is proportioned to give you the maximum amount of sparkle. The GIA Cut Scale ranges from Excellent to Poor on round diamonds only. 

The picture below illustrates what happens when a diamond is not cut properly and how the light disperses through the diamond.

At Richard Dolgin Private Jeweler we suggest that our customers purchase Ideal cut diamonds. Without maximum brilliance there is no real reason to buy a diamond. Ideal cut is what makes your friends say "Did you see her diamond?".

When you come to our diamond lab at Richard Dolgin Private Jeweler, we will explain in detail the characteristics of a well cut diamond and use our sources to find you the finest cut diamond available.
