It goes without saying that the hallmark of any brand is consistency and complete control of manufacturing. It became obvious during Hearts On Fire’s research that traditional cutting methods were producing inadequate results.
Why had no one noticed? The high-frequency polishing left lines on the surface of the diamond during the faceting process – lines that were invisible at 10x power magnification, but obvious at 100x power magnification. The culprit was identified as vibration, transferred from traditional diamond wheels to the tools that hold the diamond during the process…effectively impairing the surface.
Optical physics dictates that the more highly polished a surface, the more light is absorbed, refracted, reflected etc. In other words, surface aberration obstructs and impedes light. However, identifying the cause was one thing, finding the solution was a daunting task...
First, you can’t fix what you can’t see. Recognizing the limitations of the hand-held loupe that has been used by diamond cutters for centuries, Hearts On Fire (in partnership with Eurostar) would instead incorporate high definition cameras and monitors with on screen templates into the diamond cutting process. This combination, together with laser measuring devices, would render hand held loupes and protractors obsolete. This technological breakthrough would give diamond cutters the ability to view the facet at 100x power magnification, and therefore the ability to improve every aspect of the process by which we measure cut - proportion, symmetry and polish.
To this end, Hearts On Fire and its partners would commit an incredible amount of resources. Combinations of natural and composite materials would be tried and tested to construct the benches. Aviation quality bearings would become the mainstay in the motors that drive the wheels which of course would be micro balanced and leveled. Recalibration of tools became a monthly ritual to make sure that they maintained zero tolerance. This technology couldn’t be bought…it had to be invented. Everything would have to be manufactured on site in our own engineering dept. The resulting vibration free environment would be more akin to a NASA space center than a diamond cutting facility.
