Asscher Cut Diamond Rings

Asscher cut diamond rings are defined by geometric precision rather than conventional brilliant-cut sparkle. The Asscher is a square step-cut diamond with cropped corners and broad, parallel facets that create repeated reflections through the stone. Viewed face-up, these facets form a distinctive symmetrical pattern often described as a “hall of mirrors”, giving the diamond a strong sense of depth and architectural structure.

Developed in the early 1900s and later closely associated with Art Deco jewellery, the Asscher cut remains distinctive because its open facet pattern reveals more of the diamond itself. Clarity, symmetry, proportions and facet alignment therefore deserve particular attention when selecting a stone.

At Polished Diamonds, you can choose a certified natural or lab-grown Asscher cut diamond in a solitaire diamond ring, halo diamond ring, vintage-inspired design or a completely custom setting.

Choosing an Asscher Cut Diamond

An Asscher is a fancy-shape diamond, so selecting one requires more than looking for a single overall cut grade. Compare its actual length and width, symmetry, polish, clarity and face-up appearance, and inspect how evenly the step facets meet around the centre of the stone.

A length-to-width ratio close to 1.00 creates the distinctly square appearance associated with an Asscher. Carat weight should also be considered alongside millimetre dimensions because two diamonds of similar weight can present differently when viewed from above.

The open step facets do less to disguise inclusions than brilliant-style faceting, making clarity particularly important to assess visually. Rather than selecting a clarity grade in isolation, consider whether inclusions can actually be seen through the large table and how they affect the overall pattern of the diamond.

How an Asscher Cut Reflects Light

Asscher diamonds handle light differently from round brilliant, princess and radiant cuts. Instead of producing many small flashes of scintillation, their broad step facets create larger areas of light and dark contrast that appear to repeat toward the centre of the diamond.

A well-balanced Asscher should show an orderly, symmetrical pattern with clear depth rather than appearing flat or visually uneven. This is one reason you should view and compare individual diamonds rather than choose based on carat, colour, and clarity grades alone.

Asscher Cut vs Emerald and Princess Diamonds

The emerald cut is the Asscher’s closest relative because both use step facets and produce broad flashes of light. The main visual distinction is proportion: an Asscher is essentially square with cropped corners, while an emerald cut has a longer rectangular outline.

A princess cut is also usually square, but uses brilliant-style faceting. It therefore produces a livelier pattern of smaller flashes rather than the Asscher’s more structured, mirror-like appearance.

Custom Asscher Cut Diamond Rings Made in New Zealand

Asscher cuts are available in both natural diamonds and lab-grown diamonds, with options in platinum, white gold, yellow gold and rose gold.

For a custom Asscher ring, the actual diamond measurements can be incorporated into our CAD model so the setting, claw placement, cropped corners, band proportions and overall profile are developed around the individual stone. Choose an existing design to personalise or design your own diamond ring with our team.

Your ring is then crafted through our New Zealand workshop, with design studios in Auckland, Wellington and Christchurch for clients who want to compare diamonds and settings in person.
