Asscher Cut Lab Grown Diamond Rings

The asscher cut is a square step cut with cropped corners and a deep pavilion, patented by Joseph Asscher in 1902 and revived through the Art Deco period. It trades the fire of a brilliant cut for clarity and depth, drawing the eye downward through concentric squares rather than scattering light across the surface. Every asscher here is a real CVD lab grown diamond, VVS clarity, D-E-F colorless.

How is an asscher different from an emerald cut?

Proportion, mainly. An emerald cut is rectangular; an asscher is square, with a length-to-width ratio close to 1.0. The asscher also has a smaller table and deeper pavilion, which produces the distinctive windmill pattern visible when you look straight down into the stone.

Why does clarity matter so much in an asscher?

Because a step cut has open, mirror-like facets with nothing to disguise an inclusion. In a brilliant cut, scattered light hides small flaws; in an asscher you look straight through to the bottom. This is exactly why Ronora sets VVS clarity here rather than dropping a grade.

Frequently asked questions

Is it rare? Among the less common shapes, which is part of the appeal. Asscher cuts read as a deliberate choice.

Are the corners fragile? No. The cropped corners are far more durable than a princess cut's sharp points.
