The Asscher shape diamond was developed in 1902 by the Asscher Brothers of Holland and is a variation of an Emerald cut. The Asscher cut is a stepped square cut also known as a Modified Square Emerald cut. This cut offers a small table (largest facet on a stone) high crown (top portion of the stone) deep pavilions (lower portion of the stone), and cut corners. With its 72 wide step facets it resembles that of an octagon and sparkles like the Round Brilliant. This cut is designed to draw your eye directly into the diamond.
Asscher Diamond "Cut"
The cut of a diamond determines its brilliance. A poorly cut diamond will have a dull appearance even if it has perfect color and clarity. The cut is considered one of the most important diamond characteristics by gemologists. It is based on factors that determine the light performance, dimensions, and finish of a stone.
The cut should reflect the maximum amount of light to the viewer's eye. For example, if a diamond is cut too shallow light will be lost out of the pavilion (bottom) and the diamond will lose brilliance. If the diamond is cut too deep, the light will escape through the sides and the diamond will appear dark.
Since Asscher cut diamonds are designed with larger facets, you need to be sure that you are familiar with the qualities of a good cut. An Asscher diamond makes a beautiful engagement ring as a solitaire or set with other stones.
