Asscher Cut Diamonds: Vintage Brilliance in a Square Shape

What Is an Asscher Cut Diamond?

Developed in 1902 by Joseph Asscher in Amsterdam, the Asscher cut is a square step-cut diamond with cropped corners and a high crown. It is often compared to an emerald cut but appears more square and delivers a dramatic open-centre mirror effect. Browse our rings.

Frequently Asked Questions

Is an Asscher cut more expensive than a round brilliant?

Yes, Asscher cuts have lower yield from rough diamond, so per carat prices run about 10-20% higher than equivalent round brilliants.

Does an Asscher cut look bigger than a round?

The Asscher has a large open table that makes it appear larger than its actual carat weight, especially from the top view.

What setting suits an Asscher cut?

Bezel, cathedral and halo settings complement the Art Deco character; a plain solitaire keeps the focus on the step-cut mirrors.
