Diamond Education
Understanding Diamond Quality
Every GIA certified diamond is graded on the 4Cs: Cut, Color, Clarity, and Carat. Our experts will help you understand how these factors affect a diamond's beauty and value, so you can make an informed choice.
Cut
The most important factor for brilliance. A well-cut diamond sparkles magnificently.
Color
Graded D to Z. Near-colorless diamonds (G-H) offer excellent value.
Clarity
Most inclusions are invisible to the naked eye. VS and SI grades offer great value.
Carat
Diamond weight. Larger isn't always better—cut quality matters more.
