Asscher Cut Diamond Shape
The Essential 7C's
Every diamond has its own story, and every lady her own style.
At this point it should be noted that the shape of a diamond
can also be referred to as its “cut”, like a round or princess cut.
However, this should not be confused with the more commonly used term of
diamond cut, which describes how well the diamond has been polished
from the raw material (see section on diamond cut).
At Seventy Seven Diamonds we cater to the detailed wishes of
every customer and want to ensure that they are well-informed about
every diamond shape available. Our selection of beautiful shapes is

1. The Basics
Also referred to as: SQUARE EMERALD CUT
|Brightest step cut, "hall of mirrors" effect.
||50 or 58 (Royal Asscher has 74)
||1.00 - 1.05
||Art-deco era, early 20th Century
||Clarity VS1/VS2 and higher is optimal.
The Asscher cut is a unique shape with prismatic brilliance
and a rectangular-faceted pavilion in the same style as the emerald cut.
The standard number of main facets on an Asscher cut is usually 58 and
the typical ratio for the more popular square-shaped Asscher cuts is
1.00 to 1.05.
The width of the cut corners may vary. With its deep pavilion,
faceted culet, high crown and small table, the Asscher cut allows for
tremendous lustre and creates a fascinating optical illusion known as
the “Hall of Mirrors” effect.
The Asscher cut is referred to as a Square Emerald cut on a
laboratory certificate, such as GIA or AGS. Although confusion reigns
about what the differences are between an Asscher cut and a Square
Emerald cut, they are in fact the same thing. However, there also exists
a much rarer Royal Asscher cut, which is a patented version of the
original Asscher cut with wide cut corners and 74 facets (instead of
58), and is classified as an octagonal step cut by the GIA.
3. Expert Advice
"To fully appreciate the Asscher design, it is advisable
to select a diamond of higher clarity (VS2 and above for GIA and VS1 and
above for EGL, to ensure it is completely eye clean).
A table and depth percentage between 60 – 73.5% and 51 - 77% respectively is also recommended."
4. History & Background
Named after its creator Joseph Asscher, owner of the
Amsterdam-based diamond company of the same name, the Asscher cut was
developed in the early 20th century at the birth of the stylish and
popular Art Deco movement. Joseph Asscher rose to fame several years
later when he was commissioned by King Edward VII to cut the famous
3,106-carat Cullinan diamond for the English crown jewels. In 1980 Her
Majesty Queen Juliana of Holland granted the Asscher Diamond Company a
royal title in recognition of the role the Asscher family and company
had held in the diamond industry. This cut’s popularity peaked in the
late 1920s but remained a somewhat rare commodity for the remainder of
the century, available only in antique shops and specialised Art Deco
jewellers. At the onset of the new millennium, following considerable
research and development, the Asscher cut was redesigned with new
specifications and additional facets for a more brilliant shine, and has
since regained its popularity.
