Understanding the four Cs

Four characteristics decide how a diamond looks and what it costs.


  • Cut

    The one the eye notices first. Cut controls how light travels through a stone and returns as brilliance.

  • Color

    Graded from colorless down through faint warmth. Near-colorless grades face up white for far less.

  • Clarity

    Natural marks formed underground or during the lab grow process. What matters is whether you can see them, not whether they exist.

  • Carat

    Weight, not size. Buying just under a round number keeps the look and lowers the price.
