Invented by the Royal Asscher Diamond Company in 1902 the Asscher cut didn’t gain popularity until the Art Deco era in the 1920s. This diamond is one of the very first patented diamond cuts in the world. At that time the patent was valid for 50 years.
Classic asscher cut diamonds are cut into squares and resemble emerald cuts which are rectangular. But asscher cut diamonds have larger step facets, a higher crown, and a smaller table. Be careful, often people ask for asscher cuts they are just getting square emerald cuts.
The corners are cropped which give the shape an octagonal appearance. The asscher is typically more brilliant then it’s cousin the emerald cut. Asscher cut diamonds from the 1920s and 1930s are very rare.
