The Asscher cut is a glamorous vintage-inspired square diamond shape making a dramatic comeback. First designed in the early 1900s, Asscher cut diamonds feature dramatically deep pavilions and faceted corners that refract light in a unique octagonal array.
This guide will cover everything you need to know about Asscher diamonds including their history, cutting specifications, pricing, settings, and frequently asked questions.
The Asscher cut was developed and patented in 1902 by the Asscher Brothers diamond company in Holland. The Asschers were renowned for their Diamond Trading Company.
Breaking from tradition, the Asscher cut was conceptualized as an early “designer” shape. It required brand new faceting arrangements to achieve the cropped square outline with faceted corners.
The cut quickly gained popularity during the Art Deco era between 1920-1930s for its evocative octagonal brilliance and strong geometric appeal. Asscher cut stones accented the bold lines and angles of Art Deco jewelry design.
After the Art Deco period, Asscher cut diamond popularity waned as brilliant rounds and emerald cuts took over. Few jewelers possessed the skill to properly facet Asschers.
In 2001, the Asscher Brothers company, now Royal Asscher, relaunched the Asscher shape for a new millennium. A renewed fascination with vintage styles has made the Asscher cut newly popular.
The Asscher cut brings together emerald’s stepped facets with a square outline. It is actually an early precursor to the development of the emerald cut.
The precisely calculated facet arrangement creates dramatic, hall-of-mirrors optical effects. Light travels down the pavilion, reflects off the sides, and returns through the table and crown.
When cut with proper proportions, Asscher diamonds exhibit a balanced and captivating interplay between steely squares of light and dark. The cropped corners frame fiery flashes of color.
Today’s Asscher cuts have some variations from the original specs, with slightly larger tables and higher crowns to enhance brilliance. When expertly cut, they shine brightly while preserving the distinctive Asscher look.
Like other diamonds, Asschers are graded using the 4Cs:
With its deep pavilion, the Asscher cut retains more weight than a similarly sized emerald cut, so carat sizes tend to run smaller visually. An ideal 1.00 ct Asscher appears more like an 0.80 ct emerald.
The Asscher cut maximizes visual impact when mounted in simple, geometric settings that accentuate the square shape:
For vintage appeal, Asschers look beautiful in filigree or milgrain-accented settings. Modern tension setting and split shanks also create drama. Avoid overly ornate mountings that distract from the Asscher’s straight lines and octagonal brilliance.
Price trends for 1 carat Asscher diamonds:
Asschers offer reasonable value compared to equivalently sized emerald cuts or cushions. Their historically significant look makes them worth the slight premium over other square shapes.
How does Asscher brilliance compare to other shapes?
With proper cutting, Asschers exhibit exceptional fire and brilliance. Light reflects brightly through the large table. Their sparkle exceeds emerald cut but lags slightly behind princess cut.
Do all Asscher diamonds have the hall-of-mirrors effect?
The strong octagonal optical effect only occurs with precise faceting. Well-cut Asschers have more scintillation and contrast between the table, crown, and pavilion. Avoid poorly made Asschers.
Should I choose Asscher or emerald cut?
Asscher has more sparkle while emerald has a more clean, elegant look. Asscher also tends to cost slightly less. Choose emerald for understated sophistication or Asscher for high-contrast sparkle.
Do Asscher diamonds show color?
Like emerald cut, Asschers typically face up with very faint color. Go with G-J color grades to maximize value since near colorless grades are still affordable.
How does Asscher carat weight compare to other shapes?
Due to its deeper pavilion, Asschers weigh more than emerald cut. But the square shape makes them appear slightly smaller than round diamonds of the same carat.
With its captivating optical properties and vintage style, the revived Asscher cut offers a truly distinct diamond shape. When expertly cut, Asscher diamonds display a marvelous interplay of light for brides-to-be and diamond lovers wanting a touch of 1920s panache.
