Asscher cuts look similar to emerald cuts with the most obvious difference being that they are square, as opposed to rectangular. This cut features large step facets and a high crown that produces a brilliance unlike any other shape. In fact, diamond experts often refer to the shine and sparkle of an Asscher cut diamond or moissanite as an endless hallway with reflective mirrors.
Although the Asscher cut is known as a square shape, it is actually somewhat octagonal since all four corners are cropped. However, these cropped corners are not noticeable once the diamond is mounted into a four-prong setting, unlike a true octagon.
