A Passion & Our Calling

A love affair of six generations

As his great-great-great-grandfather did, Mike Asscher continues in the House of Royal Asscher's trusted tradition of designing the finest diamond cuts ever. The calling for craftsmanship results in beautiful diamonds - the object of our desire and passion at Royal Asscher.

“At the heart of all we do is a legacy of love for diamonds”

The ROYAL ASSCHER® Cut

Almost 100 years after the Asscher Cut was first originated byJoseph Asscher, his great-grand nephews Edward and Joop revised the design, adding 16 additional facets to make it the reminiscent of the Cullinan II diamond of the Imperial State Crown.

The result is a ravishing 74 facet perfectly square diamond, absorbing the light from each angle. The Royal Asscher Cut catches the eye with the brilliance of a round cut and mesmerizes it with the rainbow effect of an emerald cut.

The Royal Asscher Cut’s unique aesthetic inspired our tradition of 74 facets in each of our patented diamond cuts.

The ROYAL ASSCHER® Brilliant

Our Royal Asscher Brilliant takes the most enduringly popular classic diamond cut and gives it extra head-turning sparkle.

By adding facets on the outside of the diamond, the Royal Asscher Brilliant removes some of the darker elements seen in a traditional round diamond. The effect is a crisp, clear and different diamond, a fresh generation of beauty for this timeless, beloved shape.

Finding your diamond

Sometime in 1854, guided by a stone's voice, Joseph Asscher crafted a diamond so stunning and singular, a work of timeless beauty worthy of the billions of years it took to be created. That moment sealed the Asschers’ destiny, as six generations later, the gift of hearing a diamond’s whisper remains a sixth sense of the family. Discovering your Royal Asscher diamond is a breathtaking moment defined by a stone’s voice that only you can hear. Since 1854, it’s been our privilege and pleasure to make the introduction between your diamond and you.

The 4Cs & what you don’t see

Go beyond the 4Cs, develop your eye for shape and details, and always remember, the right diamond, the one that's yours, it will speak to you. So choose your diamond with your heart for that's where its whisper is heard.”

- Advice of the Asscher family


A diamond takes billions of years to form, and across this vast amount of time, each diamond develops its identity and perfect natural beauty.



Every diamond is unique, with its own personality, characteristics, and energy. Each diamond is as individual as a fingerprint and as different from another as two snowflakes.


The 4Cs - Color, Cut, Clarity, & Carat are measurements used in defining a diamond's value. But beyond the 4Cs is another measure essential in ascertaining a diamond's true beauty - the stirring felt in your heart when you meet it. But until that moment arrives, discover the more conventional aspects of a diamond that make the difference.

Legendary Diamonds

“Our family entered the diamond cutting trade out of necessity. And from necessity bloomed passion, transforming a skill into a calling heard and answered by six generations of Asschers since our first cut in 1854. Like Michelangelo, who saw the angel in the marble and carved until he set him free, we Asscher’s can’t help but see the ultimate beauty residing in every rough diamond, and our hands cut and polish to set that beauty free. Our calling is why, I believe, a legend grew around the Asscher name, bringing the most incredible diamonds and equally incredible diamond lovers to us with the same request - to reveal the infinite beauty hidden within the stone.”

- Edward AsscherThe greatest diamonds in the world have been shaped by Asscher hands. We invite you to discover some of these remarkable stories.
