Blueprinting, 3-Dimentional symmetry, Zero Tolerance cutting result in a diamond of unmatched sparkle and beauty. However, these elements are only the final platform upon which the ultimate beauty of a RAND diamond is acheived.
The making of the fine musical instrument utilizes the finest components and technological skills. But only when tuned by the maestros ear to perfection does any musical instrument truly become a masterpiece. Without this final human adjustment the true expression of the instrument is lost. This too is equally true perfecting the expression of a RAND diamond.
After a RAND diamond has met every measurable specification it is given to one of a select group of master diamond cutters. These master cutters then fine tune each individual RAND diamond by eye just as a maestro would fine tune a Stradivarius by ear. Interestingly, just as with a musical instrument, this fine fine tuning process can only be done by a human being utilizing their skill and senses, something that no machine can define or measure.
Your eye can see the result.
