The Asscher Cut was developed by Joseph Asscher, who was commissioned by the Royal Family to cut the world's largest diamond in history; the 3,106ct Cullinan diamond, after which he invented the now-famous Asscher cut. This cut reached its peak of popularity in the 1920's in very limited production. Up until 2001, the Asscher cut was a hard to come by commodity and available mostly in antique shops or from art deco jewellery dealers. For more information, click here.
