Cut, Color, and Clarity
When it comes down to value, the cut of the diamond is the most important aspect of it. Among the different cuts, the highest quality is affinity, which imparts perfect symmetry to the stone. This ensures that the diamond produces the maximum amount of brilliance and fire, which will directly affect how much it costs.

These flaws are unique to each diamond, and can also help appraise it. When it comes to color, colorless diamonds are the most valuable, since they allow the most light to pass through, creating maximum brilliance and fire.
