Cut

A diamond that is masterfully cut displays maximum brilliance and fire.  Cut and proportion are extremely important because they have the greatest influence on the sparkle and overall value of a stone.  A diamond that is well cut reflects light from one facet to another and disperses it back through the top of the stone.
