Asscher Cut Diamond Rings

An asscher is a square diamond with cropped corners and stepped facets that form a pattern of nested squares when you look down into it. Most of our asscher rings are eternity and half eternity bands, where a row of these squares, each framed in metal, gives a clean geometric line. The collection also includes two asscher wedding rings, in yellow, white or rose gold.

A Square Step Cut

An asscher has the same step faceting as an emerald cut, but in a square. Its pavilion is deep and its crown is high, and that depth is what creates its signature look: from above, the facet edges line up into concentric squares that run toward the center, often described as a windmill or a hall of mirrors. The traditional asscher has 58 facets.

A good asscher is a true square, with a length-to-width ratio of about 1.00 to 1.05, and its four cropped corners should be equal in size. Uneven corners or a stone that's slightly rectangular breaks the pattern. If you prefer the same step-cut look in a longer shape, see our emerald cut diamond rings.

Where the Asscher Came From

Joseph Asscher of Amsterdam introduced the cut in 1902. His family's firm went on to split the Cullinan, the largest gem diamond ever found, in 1908. The asscher reached its peak of popularity in the 1920s and 1930s, when its strict geometry matched Art Deco design, and that connection is why it still reads as vintage today. Our Art Deco engagement rings guide covers the style in more depth.

Why Asschers Suit Eternity Bands

Square stones meet edge to edge without the gaps you get between rounds. With an asscher, each stone also carries its own stepped square pattern, so a full band shows a repeating grid of small mirrors rather than a blur of sparkle. Setting each asscher in a bezel adds a thin metal line around every stone, which sharpens the geometry and covers the corners, the part of a square stone most likely to chip.

The Bands

Our asscher eternity and half eternity bands range from about 2 carats to 8.80 carats in total weight. Most are bezel set.

  • All lab-grown diamond, in half eternity and full eternity styles, up to the 8.80 carat band.
  • Black diamond, with natural, color-treated black diamonds, either all black or alternating with white lab-grown diamonds.
  • Lab-created ruby, blue sapphire or emerald, as a solid band of one color.
  • Gemstone and diamond, alternating stone by stone or split half and half around the ring.

A full band carries stones all the way around and suits a ring that won't be resized. A half eternity ring keeps stones across the top only, which makes it easier to resize and more comfortable beside another ring. Read more in our eternity and half eternity ring guide, or browse half eternity rings and lab-grown diamond eternity rings.

The colored stones are all lab-created. For them in other shapes, see lab-grown ruby rings, sapphire rings and lab-grown emerald rings. More black diamond designs are in our black diamond rings.

Clarity and Color in an Asscher

Because an asscher's facets are wide and flat, there's little sparkle to distract the eye, and inclusions near the center are easy to spot. That matters most in a large center stone. In an eternity band, each stone is small enough that minor inclusions rarely show. For color, the deep pavilion can hold a hint of warmth, which white gold makes more noticeable and yellow or rose gold softens.

Asscher Wedding Rings

Two 1.50 carat asscher wedding rings complete the collection, one in lab-grown diamonds and one in natural diamonds. In both, the 1.50 carats is the total weight of several asscher stones set across the band. More styles are in our women's wedding bands.

Asscher Engagement Rings

Asscher engagement rings are joining this collection soon. If you'd like one before they launch, or in a setting we don't show, ask about a custom design. For other square and step-cut looks with a vintage feel, our vintage engagement rings guide has ideas.

Certificates

Natural asscher diamonds go up to 1 carat, and any natural diamond of 0.50 carat or more includes an IGI or GIA report. Lab-grown diamonds of 1 carat or more include an IGI report. Stones below those sizes, which covers the stones in our bands, aren't individually certified.

A ring priced above $800 includes a jewelry certificate from GSI, an independent lab, that covers the finished piece. Compare origins in our natural diamond rings and lab-grown diamond rings.

Other asscher pieces are in our asscher cut diamond jewelry collection.

FAQs

Both are step cuts with cropped corners. An asscher is square and cut deeper, which creates its pattern of nested squares, while an emerald cut is a rectangle. See the longer version in our emerald cut rings.

No. The rubies, sapphires and emeralds are lab-created, and the black diamonds are natural but color-treated, paired in some bands with white lab-grown diamonds. More lab-created color is in our ruby ring collection.
