What is the Most Valuable Cut of Diamond?

The most valuable diamond cut is generally considered to be the round brilliant cut. This cut is designed to maximize a diamond’s sparkle by having 58 facets, carefully positioned to reflect light. Its popularity and the amount of rough diamond material required to create this cut also contribute to its higher price. Other valuable cuts include the princess and cushion cuts, though the round brilliant remains the most sought after for its brilliance.
