Cut

Commonly not emphasized in evaluating the quality of many diamonds is its unique cut. The cut directly correlates to the amount of light that enters the diamond and is refracted back to the eye. This allows for optimal brilliance and visual dominance.
Below are examples of how cut can affect your diamonds appearance. Shown are the Ideal Cut and Inferior Cuts. A third kind of cut is thePremium Cut. A Premium Cut diamond demonstrates subtle variations from the Ideal Cut. Although dimensional differences affect a diamond's reflection of light, a Premium Cut still achieves a harmonious balance between its proportions and the display of brilliance.
