Lab Diamond Asscher Cut Engagement Rings

About This Shape

Developed in 1902 by the Asscher Brothers of Holland, this shape was the first patented cut. It features a high crown and small table that creates exceptional depth and light play. Unlike brilliant cuts that sparkle intensely, the asscher cut diamond produces broad flashes of light with a subtle, sophisticated beauty. The square shape with distinctive corners makes it instantly recognisable and appeals to those who appreciate Art Deco aesthetics.

Lab Grown Asscher Options

Our lab grown asscher pieces offer the same optical properties as mined stones. Each comes with independent certification confirming clarity, colour and carat weight. The step cut nature means clarity is particularly important, and choosing lab grown allows you to select higher grades within your budget. Visit our site for more information on our certification process.

Vintage Asscher Styling

The vintage aesthetic perfectly suits period inspired designs. This shape was popularised during the Art Deco era and remains associated with that glamorous period. Milgrain detailing and geometric side stones complement the clean lines of the centre stone. Our inspired pieces capture this heritage while using modern construction techniques for durability.

Choosing Your Stone

We recommend VS2 clarity or above for this shape, as inclusions are more visible than in brilliant cuts. For colour, G or better ensures the stone appears white in most settings. Book an appointment at our showroom to compare stones side by side and find the perfect balance for your preferences and budget.

FAQs

Is this shape more expensive?

Not necessarily. While it can command a premium due to the higher clarity grades typically required, the price per carat is often lower than round brilliants. Our options make this sophisticated shape accessible at various price points.

Why isn't this shape more popular?

It appeals to a specific aesthetic preference. Those who love understated elegance and Art Deco styling gravitate toward this shape, while others prefer the intense sparkle of brilliant cuts. It's a matter of personal taste rather than quality.

What setting works best?

Four prong settings showcase the corners beautifully, while bezel settings offer a sleek, modern look. Halo designs add extra sparkle around the step cut centre. The clean lines of this shape also work well with baguette side stones for a classic Art Deco appearance.
