At Royal Asscher Diamonds, innovation has been at the heart of our heritage since 1854. For more than six generations, our family name has been synonymous with diamond craftsmanship, precision, and the relentless pursuit of brilliance. This legacy is not only preserved but continually redefined through our patented diamond cuts, rare innovations in the world of fine jewelry that set us apart from other diamond houses.

Why Royal Asscher Patents Its Diamond Cuts

Every patented Royal Asscher diamond cut is the result of years, often generations of dedicated research, artistry, and refinement. Patenting goes beyond legal protection; it is a recognition of the intellectual, technical, and artistic value we embed in every facet. By securing patents, we preserve the exclusivity of our designs and ensure that when you choose a Royal Asscher diamond, you are investing in a jewel of unmatched brilliance and authenticity, one that cannot be replicated by any other jeweler.

Every patented Royal Asscher diamond tells a story of innovation, craftsmanship, and legacy.

The Royal Asscher Cut: A World’s First

Our signature, the Royal Asscher Cut, is the ultimate expression of this philosophy. Building upon the pioneering Original Asscher Cut of 1902, the world’s first patented diamond cut, we elevated its design by adding 16 additional facets for a total of 74. This architectural precision creates our hallmark “hall-of-light” effect: an optical performance that transforms every ray into breathtaking, mirrored brilliance.

A Collection Beyond the Iconic Square

Our patented diamond cuts extend beyond the iconic Royal Asscher cut.

• The Royal Asscher Cushion Cut blends vintage romance with modern brilliance, its 74 facets engineered to reduce light leakage and unleash extraordinary fire.

• The Royal Asscher Brilliant Cut reimagines the world’s most beloved diamond shape — the classic round. By adding precisely positioned facets, our master cutters have amplified light performance to a level rarely seen in round diamonds. This meticulous design intensifies fire and brilliance, creating a diamond that radiates exceptional sparkle with every movement. Its crisp beauty and vivid luminosity are unmistakable, ensuring that a Royal Asscher Brilliant Cut doesn’t just catch the light, it captures the gaze, leaving a lasting impression of elegance and radiance.

Perfecting Oval and Pear Shapes

Our Royal Asscher Oval Cut and Royal Asscher Pear Cut diamonds are meticulously designed to eliminate the bow-tie effect, delivering balanced brilliance from every angle. The Royal Asscher Pear Cut features a uniquely crafted pavilion-side culet, intensifying fire and luminosity from top to crown.

Redefining the Emerald Cut

The most recent addition, the Royal Asscher Emerald Cut, exemplifies our relentless pursuit of perfection. Traditionally admired for symmetry but known to sacrifice brilliance, the emerald cut has been reimagined by our master cutters. Through advanced pavilion redesign and precise angle adjustments, we achieved remarkable light performance without compromising its timeless elegance. This breakthrough required months of technical modeling, trial cutting, and expert craftsmanship, reflecting the artistry of six generations.

Innovation and Heritage at Royal Asscher

Every new cut begins with a question: How can we push the boundaries of light? How do we elevate beauty while preserving structural integrity?

Our process fuses advanced 3D modeling and light-ray simulation with the intuition honed over six generations. The result is a diamond that does more than sparkle, it resonates, it inspires, it speaks to the soul.

Patenting our innovations is about more than protection; it preserves the integrity of what makes a Royal Asscher diamond unique. When you choose a patented Royal Asscher diamond, you are not simply choosing a jewel. You are choosing a legacy of artistry, ingenuity, and excellence, cut into every facet.
