In 1902, Asscher Diamond Co. patented a rectilinear diamond cut. Developed by Joseph Asscher, the squarish step cuts deeply cut corners give it an almost octagonal outline. It features a small table, high crown broad step facets, deep pavilion and square culet. The Asscher cut was inspired by he table cuts of the Renaissance, however, it was a big departure from the brilliant cuts that dominated the 1800s and was a forerunner of the standard emerald cut. Because of its high crown and small table, the Asscher cut has more light and fire than an emerald cut.

This diamond has cropped corners and a stepped square cut, which draws eyes inward towards the center of the stone. It is very important than ever to consider quality when shopping for an Asscher Shape diamond. The way the stone is cut will determine how much light is reflected in and out of the diamond, which is what makes it sparkle. Asscher Shape diamonds tend have a smaller size range and must be placed in a 4 pronged setting to protect the corners of the stone from chipping.

The Asscher Shape diamonds are gaining in popularity, today. As many celebrities are being seen to wear them.
