The Peerless Diamond is a sparkling celebration of diamond brilliance and artistic excellence. The proof of the diamond’s superiority is contained in the two independent gemological reports that accompany every Peerless Diamond. When it comes to the ‘ideal’ diamond – the Peerless Diamond is simply – peerless.

What Is An Ideal-Cut Diamond?

In 1919, Marcel Tolkowsky, a Belgium-born gemologist and mathematician, was preparing his doctoral thesis. His subject was the calculation of the precise proportions of a diamond’s cut in order to absolutely maximize the diamonds’ brilliance and dispersion of light. He realized a cut and polished diamond is really a series of prisms and mirrors, and the way light is reflected within the diamond determines its beauty. If a diamond is cut too deep or too shallow, too much light escapes through its bottom and sides, resulting in lost fire, sparkle and brilliance from the top. After extensive study and calculations, Tolkowsky had his answer. It is from his work that the ideal-cut grade was born. “Ideal” is not just an adjective… it has become the industry standard for the set of proportions, ratios, and angles known as the American Ideal-Cut.

What Makes The PEERLESS diamond the ideal ideal-cut diamond?

The proof of this diamond’s superiority is contained in the two independent gemological reports that accompany every PEERLESS diamond. The first is from the American Gem Society (AGS). Their Diamond Quality document is a fastidiously-prepared report card of the PEERLESS diamond’s 4Cs. You will see that the Cut Grade shows three zeros (highest grade possible) in three primary areas from the AGS Laboratory: light performance, proportion factors and finish (polish and symmetry). “Triple-zero” diamonds like the PEERLESS diamond are very uncommon. The second gemological report is provided by GemEx. It measures your diamond’s return of light and provides you with three critical measurements of the PEERLESS diamond’s performance: how well it performs in return of white light — what is called “brilliance,” its return of color light — called “fire” — and its scintillation, called “sparkle.” The three grades the PEERLESS diamond has achieved all fall within the “Very High” range. The GemEx report confirms what the eye can clearly see… the PEERLESS diamond truly lives up to its name and is the ideal ideal-cut diamond.
