The 4Cs Guide

When purchasing a diamond, understanding the 4Cs—Cut, Color, Clarity, and Carat Weight—is essential. These characteristics determine a diamond's quality, beauty, and value.


  • Carat weight measures a diamond's size, with one carat equal to 0.2 grams.
  • Larger diamonds are generally more valuable, but other factors like cut, color, and clarity also influence a diamond's worth.
  • It's essential to balance carat weight with the other 3Cs to find a diamond that fits your budget and preferences.


  • Diamond color is graded on a scale from D (colorless) to Z (light yellow or brown).
  • The less color a diamond has, the more valuable it is. However, some fancy-colored diamonds, like pink or blue, are highly prized for their intense hues.
  • It's essential to examine diamonds in controlled lighting conditions to accurately assess their color.


  • Clarity measures the presence of internal and external flaws, called inclusions and blemishes, respectively.
  • Clarity grades range from Flawless (no inclusions or blemishes visible under 10x magnification) to Included (inclusions and/or blemishes visible to the naked eye).
  • Diamonds with higher clarity grades are rarer and more valuable. However, most inclusions are microscopic and do not affect a diamond's beauty.


  • The cut of a diamond refers to its proportions, symmetry, and polish, rather than its shape.
  • A well-cut diamond reflects light internally and externally, resulting in brilliance, sparkle, and fire.
  • The cut grade ranges from Excellent to Poor, with Excellent being the highest quality.
  • It's important to note that diamond shapes, such as round, princess, cushion, emerald, and oval, are separate from the cut grade. The shape refers to the outward appearance of the diamond, while the cut grade evaluates the quality of its proportions, symmetry, and polish.
