Modern Cushion — A Contemporary Take on the Classic Pillow Shape
Modern Cushion — A Contemporary Take on the Classic Pillow Shape
The cushion modified brilliant: extra pavilion facets, crushed-ice optics, and the dominant cushion of the modern market
The modern cushion is a cushion-shaped brilliant cut featuring contemporary facet arrangements developed in the late twentieth and early twenty-first centuries. Where the antique cushion brilliant relies on a relatively small number of large pavilion facets to produce broad, watery flashes of light, the modern cushion uses additional rows of smaller facets — chevron-shaped or needle-like — to produce a busier optical pattern frequently described as crushed ice. On laboratory reports the cut is generally identified as cushion modified brilliant, distinguishing it from the antique cushion brilliant, which retains the older facet count.
Facet arrangement and optics
A modern cushion typically retains the cushion crown — pillow-shaped outline with rounded corners and gently curved sides — but the pavilion is reworked. Where an antique cushion brilliant has eight main pavilion facets descending from the girdle to the culet, a modern cushion adds one or more rows of smaller facets between the girdle and the culet, creating four, five, or sometimes more rows of chevron-pattern faceting radiating from the culet outward.
The optical result is a stone with many smaller, sharper flashes rather than the broader, more languid flashes of the antique cushion. Some buyers and cutters describe the modern cushion's appearance as crushed ice — a busy, sparkly surface texture more comparable to a round brilliant in liveliness than to the soft glow of an antique cushion. Others describe the same optical character as needle pattern, after the elongated facet shapes that produce it.
Why the modern cushion exists
The modern cushion was developed for two reasons: yield and brilliance. Cutting an antique cushion brilliant requires a relatively well-formed piece of rough and accepts moderate weight retention; the modern cushion, with smaller facets and a more flexible facet plan, allows the cutter to optimise weight retention from irregular rough while still producing acceptable brilliance.
For coloured stones in particular, where the per-carat price escalates sharply with size, weight retention is a decisive economic consideration. The modern cushion has therefore become the dominant cushion-shaped style for coloured stones in the past two decades, and a significant portion of the cushion-cut diamond market also.
GIA terminology and the cushion modified brilliant
GIA grading reports describe modern cushions as cushion modified brilliant. The phrase modified brilliant indicates that the standard round-brilliant facet plan has been adapted to a different outline, with the precise modification depending on the cutter's design choices. A cushion modified brilliant report does not in itself tell the buyer how many additional facet rows are present or what the optical character will be; the buyer should examine the stone or its photograph for the visible facet pattern.
The corresponding term for the older facet plan is cushion brilliant without modification, sometimes written old mine cut or antique cushion depending on era and convention. Antique cushions cut in the late nineteenth and early twentieth centuries, before electric lighting standardised viewing conditions, were optimised for candlelight and produce their characteristic soft, watery glow under that illumination.
Buyer's guide
Cushion-shape buyers should ask, plainly, whether they are looking at an antique cushion brilliant or a cushion modified brilliant. The two stones can carry the same broad outline and the same rough proportions but produce notably different optical effects. The modern cushion's crushed-ice or needle pattern is preferred by some buyers and disliked by others; the antique cushion's broad watery flashes have a passionate following among collectors of vintage and reproduction antique jewellery.
For coloured stones, the choice between modern and antique cushion is largely about market preference rather than performance: both can return excellent colour and brilliance in capable hands, and the cutter's skill matters more than the facet plan.

Modern cushion proportions
Modern cushions vary widely in proportions: length-to-width ratios from roughly 1.00 (square cushion) to 1.30 (elongated cushion) are all commercially common, and individual cutters favour particular proportions for their preferred optical effect. Table size, crown angle, and pavilion depth are not standardised in the way they are for round brilliants, and the absence of a unified ideal-cut framework for cushions means that buyers should evaluate each stone face-up rather than trusting a numerical scorecard. A well-cut modern cushion will return light evenly across the face with no obvious dark patches or window in the centre.
