Aside from giving the stone its shape, the cut of a diamond or gemstone determines a stones brilliance. The Asscher cut was created in 1902 by the Royal Asscher Diamond Company and named for its founder. Asscher cut diamonds are similar to emerald cuts, but with larger step facets, a higher crown, and a smaller table. With its distinct octagon shape, the Asscher cut is most common in vintage and Art Deco jewelry but is still rare throughout history, including today.

What You Should Know About Asscher Cuts

Bold and vintage, Asscher cuts are a unique shaped stone with a unique cut that looks like steps, called step cut and similar to the effect an emerald cut has. Though they come with a rarefied and royal history, Asschers are an unconventional and uncommon choice for a few reasons: they don’t radiate as much light as other cuts, they require an extremely experienced master stone cutter to get just right.

  • More vulnerable to chipping, snagging or breaking than round or oval cuts
  • Not good for very active lifestyles

Assher cut engagement rings are a good choice for a vintage-inspired engagement ring or a bold, geometric look. They’re not a good cut for someone who wants maximum brilliance and sparkle, or for someone who wants the most carat weight for their budget. Asscher cuts are an unconventional choice, making them a good option for those that want a very unique look. If you do want an Asscher cut, it may require that you prioritize stone quality over size because this cut shows flaws more easily than others.
