Hearts On Fire has developed a diamond cut which is based on a modern round brilliant diamond cut with 58 facets. The philosophy behind their diamond manufacturing is simple: cut is the most important aspect in determining the beauty of a diamond. Working off of this philosophy, Hearts On Fire has gone to unprecedented lengths to ensure that each and every diamond they sell is cut to extreme standards of perfection.
Each Hearts On Fire diamond is cut and analyzed at 100x magnification using digital imaging technology and micro-precision templates which allow their cutters to achieve a level of precise polish and symmetry which far exceeds the industry standard. Along with this, Hearts On Fire has developed unique “vibration free” cutting wheels (powered by Rolls Royce engines) which further aid in their ability to achieve facets which are precisely polished and aligned.
