The Asscher cut is a type of diamond cut that features a square shape with cropped corners, resembling an octagon. It was developed in the early 20th century by the Asscher Brothers in Amsterdam. This cut is known for its deep pavilion and large, step-cut facets, which create a unique, vintage appearance and enhance the diamond's brilliance. Due to its design, the Asscher cut emphasizes clarity and color, making it ideal for high-quality diamonds. The cut's symmetrical lines and geometric patterns can create a mesmerizing effect, often referred to as the "hall of mirrors" look, which adds to its popularity in engagement rings and fine jewelry.
