Asscher vs Square Emerald Diamonds – What’s the Difference
— by Cullen Jewellery — Reading time 4 minutes
Choosing the perfect diamond shape is about more than aesthetics. It’s a reflection of your personality, your values, and your lifestyle. While the design of your engagement ring is an important decision, it all starts with your centre stone. Understand that, and you’re halfway there to your perfect engagement ring. Two diamond cuts that can be easily confused are the Asscher cut and the Square Emerald cut. While they may look similar at first glance, there are subtle distinctions between the two. We’re breaking down the differences, pricing, and sparkle-factor to help you decide which is right for your diamond ring or engagement ring.
Is Square Emerald Cut the same as Asscher?
The Asscher cut is a vintage-inspired diamond shape developed by the Asscher Brothers of Holland. This shape is known for its bold step-cut facets and distinct “hall of mirrors” effect. It was popularised during the Art Deco period, a time when such maximalism was celebrated – and now still speaks to those looking for a touch of old-world elegance.
The Square Emerald cut is, as the name suggests, a square version of the traditional emerald cut. Like the Asscher, it features step-cut facets, but typically has a slightly less dramatic sparkle. It’s worth noting that many jewellers use the terms interchangeably, especially because the square emerald engagement ring closely resembles the Asscher cut, with the subtle differences between these shapes generally only being noticed by experienced jewellers and gem-cutters. Asscher cut diamonds can be identified but their square cut corners that nearly resemble an octagon.
All in all, while both of these cuts share the step-cut structure, square silhouette and old-school charm, the asscher cut has more dramatic depth while a square emerald cut engagement ring is often flatter, with a subtler sparkle. Square emerald’s differ from their rectangular sibling the standard emerald cut in their ratio, with as the name suggests, square emeralds appearing less rectangular than the standard emerald cut.
Which is More Expensive?

Asscher cuts are often priced slightly higher than square emerald cuts of similar quality. This is largely due to the precision required in cutting and the greater amount of material typically lost in the process. While both cuts offer a striking, geometric elegance, they each have their own unique appeal — and the choice ultimately comes down to personal preference. At Cullen, we offer a beautiful range of lab grown asscher cuts, including diamonds, moissanite, and sapphires , so you can find the cut and quality you love within your budget.
Are Asscher cuts more sparkly than Square Emerald Cuts and Princess Cuts?
When it comes to sparkle, princess cuts are the sparkliest of the three. Square emeralds have brilliant-cut facets which maximise light return. Asscher cut diamond rings are beautiful but the long facets create a more elegant shimmer than a fiery sparkle like the princess cut. Square emerald cuts have the least sparkle, but give off a clean, understated shine.
All of these cuts offer their own charm, so the choice is down to your overall aesthetic. Each of these stones can also be incorporated into a wedding band, if the decision between each of them for a centre stone is difficult to settle on. Another cut that features the step cut faceting pattern is the elongated hexagon shape, a bold choice for those after something truly unique.
