The Asscher brothers in the Netherlands invented the Asscher cut, around the start of the 20th century. It's a step cut with a square or rectangular shape, cut corners, and a deep pavilion that gives it a distinctive and classy appearance. The concentric square facets of the Asscher cut give the diamond a distinctive pattern of bright and dark regions. The cut, which typically has 58 facets, a high crown, a small table, and is intended to enhance the diamond's brilliance and fire, typically has these features.
