Asscher Cut Diamond Engagement Rings: A Guide
The Art Deco step-cut with hypnotic depth — what defines an Asscher cut diamond, and how to choose one for an engagement ring.
Quick answer
An Asscher cut is a square step-cut diamond with cropped corners and concentric "hall of mirrors" facets. It reads elegant and vintage, showing clarity and depth more than fiery sparkle, and it suits a clean, simple setting. Made to order in solid 9, 14 or 18ct gold; diamonds natural or lab-grown, independently graded (GIA, IGI or HRD where applicable).
What is an Asscher cut?
The Asscher cut is a square step-cut with cropped (bevelled) corners, first created by the Asscher family in 1902. Instead of the many small facets of a brilliant cut, it has broad, straight steps that draw the eye inward — the famous "hall of mirrors" effect. It is a signature Art Deco look: architectural, calm and timeless.
What to look for
Because step cuts have larger, open facets, they reveal a diamond's clarity more than a brilliant cut does — so a cleaner clarity grade tends to look better in an Asscher. Colour is also more visible in the open facets. A near-square outline (length-to-width ratio around 1.00) gives the classic Asscher shape. Our diamond 4Cs guide explains how cut, clarity, colour and carat work together.
Settings that suit it
An Asscher looks best when the setting lets its geometry speak. A four-claw setting (claws on the corners) on a plain band is the timeless choice; a rubover (bezel) frames it cleanly and protects the corners; a halo adds surrounding sparkle if you want more brilliance. Simple, uncluttered bands flatter the step-cut most.
