|Unique Features||Facets||L/W Ratio||Origin||Expert Tip|

Asscher cut diamonds come from the “Step cut” family.
Meaning the pavilion (lower half of the diamond) has straight lined facets as opposed to the brilliants having multiple facets.
Asscher cut was created as an alternative to the traditional Emerald cut. You’re now able to have the beauty of the Tradition Emerald cut in a cool modern uber square look.
The great thing about Asscher cuts is they have the same depth as the emerald cut so you’re able to get a much bigger looking stone if going for Asscher vs Emerald.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, we generally suggest to select a diamond of higher clarity (VS2 and above for GIA and VS1 and above to ensure it is completely eye clean).
It looks great on its own, or surrounded by brilliants to create a nice contrast. It can also be placed in a trilogy design using different shapes to enhance the beauty of this unique cut.
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.
