Asscher Cut Diamond Engagement Rings

The Asscher cut is a striking diamond shape, instantly recognisable for its square outline with deeply trimmed corners and step-cut facets. Unlike brilliant cuts that maximise sparkle, the Asscher is designed to create a mesmerising “hall of mirrors” effect, where light reflects dramatically within its precise geometry.

Originally developed in 1902 by the Asscher brothers in Amsterdam, this cut rose to fame during the Art Deco period and remains a favorite for both vintage-inspired and modern engagement rings.

An elegant Asscher-cut diamond ring design symbolises sophistication, balance, and enduring elegance. Its octagonal form with eight defined sides often represents infinity and the everlasting nature of love. 

Associated with the glamour of the Art Deco era, this cut embodies style and heritage, making it an ideal emblem for couples seeking a meaningful design that celebrates both tradition and individuality in their engagement ring.

While Asscher diamonds represent only around 2% of all cuts worldwide, their rarity is part of their charm. They are popular among those seeking an engagement ring that feels unique and distinctive, rather than following mainstream trends. 

Their vintage appeal has been revived by celebrities and modern brides looking for alternative diamond shapes beyond round or oval, making the Asscher cut a quietly prestigious choice in the UK and beyond.

An Asscher-cut diamond features 58 facets, arranged in a precise step-cut pattern with cropped corners and a square outline. Similar to emerald cuts but with a more symmetrical structure, the Asscher cut’s facets highlight clarity and craftsmanship, making every sparkle deliberate and elegant.

An ideal Asscher diamond is cut as close to a perfect square as possible, typically with a length-to-width ratio of 1.00 to 1.05. This ensures symmetrical lines and enhances its signature step-cut brilliance. 

While some may prefer a slightly elongated look, a near-square ratio creates the most balanced and classic appearance, maximising the Asscher cut’s striking geometry and reflective hall-of-mirrors effect. To ensure your diamond achieves the best balance of brilliance and symmetry, we recommend consulting with our Hatton Garden engagement ring experts.

The right setting can elevate an Asscher diamond’s beauty. Solitaire settings highlight its clean geometry, halos add a radiant frame, and three-stone or diamond bands enhance its sparkle. 

For a vintage feel, Art Deco asscher cut engagement ring designs work beautifully, while modern settings create a contemporary edge. Contact our bespoke ring expert at Regal Hatton Garden and explore tailored setting options that best suit your style.

Asscher diamonds have large, open facets that reveal their internal characteristics more easily than other shapes. For natural Asschers rings, VS2 to SI1 clarity offers excellent value without visible flaws, while for lab-grown diamond rings, VVS1 to VS1 is ideal. 

Focus on eye-clean stones where inclusions are hidden within the facets or prongs, ensuring your diamond maintains its signature transparency and brilliance.

To preserve your Asscher diamond’s brilliance, clean it regularly using warm water, mild soap, and a soft brush. Avoid harsh chemicals that can damage the metal or stone. When not worn, store it in a separate pouch or jewellery box to prevent scratches.
