The Asscher Cut Diamond

The history of the Asscher Cut

The Asscher cut dates back to 1920. The owners and brothers of the Asscher Diamond Company (now: Royal Asscher) designed it. They made the shape for the firm, after Mr. Asscher cut and polished the Cullinan diamond in 1908. That is why the general public didn’t discover this shape until around 1920. The design of an Asscher cut diamond fits perfectly to the Art Deco period. It is, therefore, no surprise that the cut became popular very quickly. Due to the combination of the end of the Art Deco period and the development of new diamond cuts, the Asscher cut became a bit forgotten. In the following years, most of the Asscher cuts were found in vintage rings in antique shops. But at the beginning of 2000, almost out of nowhere, the Asscher cut made a great comeback. Nowadays, it’s almost just as popular as during the Roaring Twenties. asscher cut diamond on leather background

An endless hallway of mirrors

The Asscher cut looks a lot like an Emerald cut. However, there are some important differences between the shapes of these cuts. An Asscher cut is square, while an Emerald is a rectangular diamond. Just like an Emerald cut, the Asscher has large step facets on the top and bottom of the stone. However, the corners of the Asscher are rounder than those of an Emerald cut diamond. Therefore, the Asscher almost looks round. This gives the diamond a great sparkle. Diamond experts, therefore, compare the Asscher cut often to an endless hallway full of reflecting mirrors.top and bottom view asscher cut diamond

The Asscher cut in jewelry

The crown of an Asscher cut diamond is higher and steeper than the one of a regular brilliant. This makes the cut very suitable for a solitaire setting. The Asscher has a rectangular shape. However, when it’s placed in the correct way, it almost looks round.

Impurities and color

Those who want to have an Asscher cut need to take a few things into account. The table – the top of the diamond – is relatively large. This provides you a clear view inside the diamond. Therefore, it is very important that an Asscher cut diamond has high clarity. Otherwise, you’ll see the spots and impurities immediately. Choose preferably a VS2 clarity or higher. Also regarding color, it’s better to go for a beautiful clear color. The lesser the color, the better. Though it depends on your own preference, we advise choosing an I-color or higher.

Vintage

An Asscher cut is an all-around diamond cut and is a great addition to any piece of jewelry. The style of the cut looks Art-Deco and derives from the Roaring Twenties. An Asscher diamond looks best in ‘vintage’ rings. Think of the antique look with many details and lines.

Options for an Asscher Cut diamond

Because the shape doesn’t have the optimal sparkle, a ‘halo setting’ works great for the Asscher. Opt for a ring of brilliant diamonds to surround the Asscher cut and give it an extra sparkle boost. Besides in rings, you find Asscher cuts as stud earrings and in tennis bracelets. woman holding asscher cut in spider tweezers
