Ok, ok it's not that you're lazy. It's just that shopping for diamonds can be...daunting. Here's a quick guide to what you should know before you get head out to shop. When you meet with Dana and Rad, they can answer any questions you have, but in the meantime...

The Gemological Institute of America (GIA) created this globally-recognized grading system to determine a gem's quality and define its value on the market. Appraisals of diamonds and diamond jewelry will always factor in these four metrics: 

  • Color
  • Clarity
  • Cut
  • Carat (or carats/ carat weight) 

Keep reading to learn what each of the Cs mean (in as few words as possible).


GIA Color Scale

Interestingly enough, this metric measures the absence of color since "chemically pure and structurally perfect diamond has no hue." Learn about the GIA's D-to-Z color-grading system.


The closer a diamond is to true purity, the more valuable it is. Clarity  means the absence of internal inclusions and external blemishes. The GIA  clarity scale has 6 categories and 11 grades.


Arguably the most important of the Cs, you could have a stone with great clarity and great color, but a bad cut can make your diamond appear dull and lifeless. While cut is often confused with a gem's shape (i.e. round, oval, princess, cushion, asscher, and so on), the technical definition of "cut" is actually regarding how well a stone's "facets interact with light." That is, do the polish and proportion of the facets unleash light to appear bright, fiery, and scintillating.

Carats (carat weight)

This is the weight of your gem with 1 metric "carat" = 200 milligrams.
