It is currently estimated that only 2% of diamonds are cut into this shape, thus making the Asscher a highly desired cut. Elizabeth Taylor brought it back into fashion in 1968 when she was presented with a 33 carat Asscher cut diamond ring by her then-husband, Richard Burton.

History of The Asscher Cut Diamond

In 1864, Joseph Isaac Asscher founded the I.J. Asscher diamond company in Holland, a factory that at one point would house over 500 diamond polishers and become one of the largest diamond companies in the world. The distinctive Asscher cut was born in 1902, created by Joseph’s grandson, who was named after him. Joseph took inspiration from the emerald cut but came up with a square proportion and added modifications for more brilliance. He made larger step facets, a higher crown, and a smaller table, resulting in an elegant new diamond shape.

A dynasty of diamantaires, the Asscher's were responsible for cutting some of the largest historical diamonds, such as the Cullinan for King Edward VII. The family held the patent of their mysterious cut for almost 50 years up until World War II, a dark period where the company almost went extinct. The now Royal Asscher Diamond Company still has its headquarters in Amsterdam's original Tolstraat 127 main tower, where the fifth and sixth generations of the family run the company today.

Attributes of The Asscher Cut Diamond

A square with cut-off corners, the Asscher cut must not be confused with the elongated more rectangular emerald cut. Both diamond shapes have a vintage, old classical spirit but the Asscher carries more weight in its pavilion making it more expensive than other diamond shapes, still not as expensive as round brilliant cuts.

Asscher cut diamonds present the spectacular “hall of mirrors” effect, sometimes also described as a “bottomless pool” look. Asscher cuts also display a windmill-like pattern formed by the pavilion when looked at from the top.

The 4Cs of Asscher Cut Diamonds

The 4 Cs are the standard way to determine a diamond's quality. The 4 Cs are Color, Clarity, Cut, and Carat.

Ideal Color Grades for Asscher Cut Diamonds

It's easier to perceive color in an Asscher cut diamond than in other shapes because of its large flat table and parallel facets. Go for a G or higher color grade if your engagement ring will be made in white gold or platinum. Yellow or rose gold will mask color better for lower grades such as H, I, and J.

Why Clarity Matters in Asscher Cuts

As it happens with color, internal flaws and inclusions are much easier to spot in Asscher cuts. You might want to go for a VS2 or higher. However, if inclusions are not at the center of the stone, an SI1 or SI2 grade Asscher cut diamond could still look relatively clear to the naked eye.


Choose a Very Good cut grade for your Asscher-cut diamond for maximum brilliance. Additionally, you should look for Excellent polish and Excellent symmetry grades. 

The perfect shape for an Asscher cut diamond is closer to a square or a 1.00 ratio. Most people find the range 1.00 - 1.05 to be ideal.

Asscher-cut diamond length to width ratios


Asscher-cut diamonds tend to look smaller than other diamond shapes that are the same carat weight, so keep this in mind while shopping for your diamond. This is because much of the Asscher-cut diamond's weight rests beneath the stone's girdle, and carat is simply a measure of how much the diamond weighs.
