The 4 Cs of Diamonds


Diamond professionals use the grading system developed by GIA in the 1950s, which established the use of four important factors to describe and classify diamonds: Clarity, Color, Cut, and Carat Weight.

Diamond Clarity inclusion san diego diamond

Clarity

Clarity grades are based on the number, size, relief, and positions of inclusions that can be seen under 10x magnification. Inclusions can be dark or light.

Cut

Precise workmanship is required to cut a diamond so its proportions, symmetry, and polish maximize brightness, scintillation, and fire.

Carat

Carat vs. Karat One Carat is equal to 0.20 grams. Only one in 1,000 diamonds weighs more than a carat.Karat is a unit of measure used to describe how much pure gold there is in an alloy.
