What are the Ideal Proportions of a Asscher Cut?

Asscher Shaped Diamonds are a handful when it comes to grading reports and the usual reliance people attribute to them. This is because Asscher Shapes have very independent rules to what enables them to be successful. Perhaps the most notable is the unique windmill structure of the shape which if done correctly, should be seen less and less as you head towards the center of the stone.

Below you will find useful guidelines to help you along the process in order to increase your chances of finding a great piece.

What is the recommended Length to Width Ratio of an Asscher Cut Diamond?

Personal tastes vary, but generally speaking, chances are you want to opt for an Asscher Shaped Diamond that is more Square as opposed to rectangular, as that is the most sought after option. You will find that the closer the length to width ratio is to the 1.00 range, the more square, and the further away it leans towards being rectangular.
