An asscher cut gemstone features a unique blend of a square shape and a step cut shape. The particular cut of an asscher cut gemstone features distinctive clipped corners and a hall-of-mirrors brilliance that is unique and eye-catching. Named after legendary gemstone cutter Joseph Asscher, the first asscher gemstone was cut in 1902. But it wasn't until the Art Deco movement of the 1920's that the asscher cut gemstone became an exceedingly popular choice for engagement rings and fine jewelry styles.
