Ok, ok it's not that you're lazy. It's just that shopping for diamonds can be...well, a bit overwhelming. But buying a diamond is an investment and when it comes to making a big purchase, the more information you have the better.
The Gemological Institute of America (GIA) created The 4 Cs, a 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 GIA-established metrics:
- Carat (or carats/ carat weight)
Keep reading to learn what each of the Cs mean (in as few words as possible).
Interestingly enough, this metric measures the absence of color since "chemically pure and structurally perfect diamond has no hue." Read more about about the GIA's D-to-Z color-grading system here.
The closer a diamond is to true purity, the more valuable it is. Clarity in this context 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, heart-shaped, 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.
