There are many different shapes of diamond used in jewellery and each different shape, or cut as they’re referred to in the industry, has its own history. The Asscher cut is no different, with an interesting story behind its invention, popularity, decline, and recent re-popularisation. Although it’s not currently one of the best-known diamond cuts, the Asscher cut’s history is rich and is becoming increasingly popular with celebrities and royals.
Pippa Middleton has a stunning Asscher cut engagement ring with a stunning 3.5ct stone, which is no doubt of very high quality. It’s surrounded by a pave-set halo of diamonds and the geometrical design offers an elegant vintage style.
Asscher cuts look similar to emerald cuts with the key difference being that they are square, as opposed to rectangular. This cut features large step facets and a high crown that produces a brilliance unlike any other diamond shape.
What is a Royal Asscher cut diamond?
Also known as the square emerald cut, Asscher cut diamonds are roughly square in shape when viewed from above but have cut corners for more light to enter the diamond. They typically have 50 or 58 facets and their ideal length to width ratio is 1 to 1.04. Because of their many facets, high crown, and depth, they can produce outstanding brilliance and create a ‘hall of mirrors’ effect.

It was the first patented diamond cut, protecting it from replication from other companies The Asscher cut was a staple of art deco jewellery, with its straight lines and brilliance making it perfect for the movement.
