The Ideal Cut When a round brilliant diamond has been cut to "Ideal" proportions by a master cutter, it is a splendor to behold. The Ideal Cut Diamond describes a round brilliant diamond that has been cut to exact and mathematically proven proportions. Its symmetry, with 58 exactly placed facets, produces the ultimate in luster and beauty. When a diamond is cut to the ideal proportions, all of the light entering from any direction is totally reflected through the top and is dispersed into a display of sparkling flashes and rainbow colors. |
The Premium 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. |

|
Light entering the diamond reflects internally from facet to facet and is reflected back through the top ONLY, creating maximum brilliance.
|
When a diamond is cut too deep, light leaks out of the bottom, brilliance is lost and the center of the diamond will appear to be dark.
|
When a diamond is cut too shallow, light leaks out of the bottom, brilliance is lost and the diamond appears watery, glassy and dark.
