The Asscher cut is a four-sided diamond cut, often considered a square version of the traditionally rectangular Emerald cut. A stepped cut, Asscher Cut diamonds feature straight edges and cut corners, with internal planes that balance light and dark to give a uniquely subdued and elegant sparkle.
An historical cut, the Asscher cut was originally conceived in 1902 by Joseph Asscher of the Asscher Diamond Company. Asscher is perhaps best known for being charged with the duty of cutting the Cullinan Diamond, the largest diamond ever discovered at the time, after its presentation to Edward VII. The three large diamonds Asscher cut from the Cullinan – in Cushion and Pear cuts - were set into the crown jewels, where they still remain. This high profile appointment no doubt helped boost the popularity and success of Asscher’s company and signature cut. Despite this, the popularity of this unique diamond style fell into decline until a recent rival.
In 1980 the Asscher Diamond Company was granted a royal title, and following much development and research into diamond cutting techniques, the modernised Royal Asscher Cut was revealed in 2001. It is this new cut, and its being showcased by several celebrities as the engagement ring style of choice, that have led to a new surge in popularity for this classic diamond shape.
Often used interchangeably, Asscher cuts as featured by jewellers and retailers will often adhere to the style and dimensions of the Royal Asscher cut. The most notable difference between the two is the number of facets featured in each: 58 in the classic Asscher cut and 74 in the modern Royal.
These variations, achievable through modern techniques, allows the Royal Asscher cut to achieve greater levels of brilliance than both its predecessor and the closely associated Emerald cut.
Due to the interchangeability of the Royal and Classic versions of this diamond, it may be difficult for customers to define what a typical Asscher cut looks like when based on what jewellers carry. Classic cuts can be exceedingly difficult to find which subsequently means many Asscher Cut diamonds are derivative of the more commonly found Emerald cut rather than a genuine homage to the classic design. Vashi’s highly trained and experienced staff will help ensure that your Asscher cut diamond adheres to the guidelines of this truly unique style.
For the best Asscher cut it is recommended that you select a diamond with a minimum colour of H, clarity of VS2, and very good cut.
For more modest budgets, a minimum colour of I, clarity of SI1, and very good cut can still yield very pleasing results.
A 1.00 ratio (or between 1.00 to 1.05) gives the square, symmetrical outline the Asscher cut is known for.
