The epitome of Art Deco style, the Asscher cut diamond is a square, step cut diamond with an octagonal shape. Developed by Joseph Asscher in 1902, vintage Asscher cut diamonds have even more dramatic angles and an open culet. Vintage Asscher cut diamonds are exceedingly rare, but with our keen sense of proportion, we can mindfully source modern square emerald cut diamonds that resemble vintage Asscher cut diamonds.
