The Asscher Cut Diamond: is nearly identical to the emerald cut diamond and is often reffered to as a square emerald cut. Joseph Asscher an eminent diamond cutter, who cut the 3,106 carat Cullinan diamond, developed and patented the Asscher cut diamond in 1902. The Asscher cut is a squarish step cut with an almost octagonal outline. The Asscher cut diamond has a small table, a high crown, wide step facets, a deep pavilion and square culet.
An Asscher stone is cut with a series of many parallel steps, creating a hall-of-mirrors effect when looking deeply into the stone. These steps create more internal refraction and diamond fire than typical step cut stones, such as the elongated Emerald cut.
The Asscher cut diamond became very popular in Art Deco jewellery and was a forerunner of the emerald cut. Since an Asscher cut diamond produces more fire than you see in a typical step cut diamond it has become extremely popular especially with many Hollywood stars and celebrities.
If you choose a SI-clarity graded Asscher cut diamond be sure to view the clarity plot on the diamond certificate, because this shape can highlight the clarity of the diamond. When choosing an Asscher cut diamond consider the colour grade, for colours below J-colour, in various fancy-shaped diamonds the colour may be slightly visible in its corners.
The optimum shape of an Asscher cut diamond has a Length to Width ratio of 1:1, acceptable length to width ratios can be 1.00 - 1.40 : 1 depending on the shape of the Asscher cut you desire, noting that the greater length to width ratio the more rectangular the Asscher cut diamond will be.
