What Is a Cushion Cut Moissanite?
Cushion cut moissanite combines a square or rectangular outline with rounded corners and brilliant-style faceting. Often described as a pillow-shaped stone, the cushion has softer edges than princess and radiant cuts while maintaining a clearly defined four-sided silhouette.
Cushion cuts can vary considerably in their proportions and internal facet patterns. Some appear nearly square, while others are distinctly elongated. These differences allow cushion moissanite to range from compact, balanced shapes to longer silhouettes with greater vertical finger coverage.
Traditional vs. Elongated Cushion Moissanite
Traditional cushion cuts have proportions relatively close to square, creating the classic pillow-shaped appearance associated with the cut.
Elongated cushion moissanite has a higher length-to-width ratio, producing a more rectangular silhouette while retaining the cushion's characteristic rounded corners.
The additional length can provide greater vertical coverage along the finger. This makes elongated cushions an option for buyers who like the proportions of oval or radiant center stones but prefer the softer outline of a cushion.
Neither proportion is inherently better. The choice depends on whether you prefer a balanced square appearance or a longer center stone.
Choosing a Cushion Moissanite Length-to-Width Ratio
Length-to-width ratio is one of the most useful measurements for understanding how a cushion stone will appear.
Ratios closer to 1.00 produce a squarer cushion. As the ratio increases, the stone becomes progressively more elongated.
Two cushion moissanite stones with similar diamond equivalent weights can therefore look noticeably different when viewed from above.
Actual length and width measurements should be considered alongside equivalent carat weight when choosing between traditional and elongated cushions.
Cushion Faceting and the “Crushed Ice” Appearance
Cushion cuts can have different internal facet arrangements, which can significantly affect their appearance.
Some cushions display larger, more clearly defined flashes of light. Others produce a finer pattern of numerous smaller reflections, sometimes described as a “crushed ice” appearance.
Crushed ice is an informal visual description rather than an official gemstone quality grade. It describes the fragmented pattern of reflections visible within certain cushion and modified brilliant facet arrangements.
Neither appearance is universally preferable. The choice comes down to whether you prefer larger, more defined reflections or a finer pattern of scintillation.
Cushion Moissanite Ring Settings
Cushion moissanite works with a wide range of engagement ring settings.
Solitaire Moissanite Engagement Rings keep attention on the center stone and make its square or elongated proportions particularly visible.
Pavé Moissanite Engagement Rings add smaller stones along the band for additional brilliance.
Hidden Halo Moissanite Engagement Rings position accent stones beneath the center stone, adding profile detail while preserving the cushion outline from above.
Halo Moissanite Engagement Rings surround the cushion center with smaller stones to increase overall brilliance and visual presence.
Three Stone Moissanite Engagement Rings pair a cushion center with complementary side stones for additional width across the finger.
Bezel settings surround the center stone with precious metal and can emphasize the cushion's rounded perimeter while providing additional protection.
Cushion Moissanite by Equivalent Carat Weight
Moissanite is commonly described using diamond equivalent weight (DEW) to communicate approximate visual size relative to a diamond.
Because cushion stones can vary from square to distinctly elongated, actual millimeter dimensions are particularly useful when comparing stones of similar equivalent weights.

Cushion vs. Radiant Moissanite
Cushion and radiant moissanite can both have square or elongated proportions and brilliant-style faceting, but their outlines differ.
Radiant Cut Moissanite Engagement Rings generally have straighter sides and cropped corners, creating a more angular geometric appearance.
Cushion cuts have rounded corners and softer sides. An elongated cushion can therefore provide proportions similar to an elongated radiant while maintaining a gentler silhouette.
Cushion vs. Princess Cut Moissanite
Cushion and princess moissanite can both have square proportions, but their geometry is noticeably different.
Princess Cut Moissanite Engagement Rings typically have straight sides and four sharp corners, producing a crisp square outline.
Cushion moissanite has rounded corners and softer sides, creating the pillow-shaped appearance associated with the cut.
Elongated Cushion vs. Oval Moissanite
Elongated cushion and oval moissanite both provide additional vertical finger coverage, but their outlines remain distinct.
Oval Moissanite Engagement Rings have a continuous curved perimeter without corners.
An elongated cushion retains four identifiable sides and rounded corners, giving it a more structured rectangular appearance while maintaining softer geometry than a radiant.
Cushion Moissanite vs. Cushion Lab Diamond
Cushion moissanite and cushion lab grown diamonds can share very similar square or elongated silhouettes, but they are different gemstones.
Moissanite is silicon carbide and has greater dispersion than diamond, which can produce more noticeable flashes of spectral color. A lab grown diamond is crystallized carbon and has the same fundamental chemical composition and physical properties as a mined diamond.

Frequently Asked Questions
What is a cushion cut moissanite?
Cushion cut moissanite is a silicon carbide gemstone fashioned into a square or rectangular shape with rounded corners and brilliant-style faceting.
What is an elongated cushion moissanite?
An elongated cushion has a greater difference between its length and width, producing a rectangular rather than approximately square silhouette while retaining the rounded corners of a cushion cut.
What is the best length-to-width ratio for cushion moissanite?
There is no universal ideal ratio. Ratios closer to 1.00 create a squarer cushion, while higher ratios produce increasingly elongated proportions. The preferred ratio depends on the silhouette and finger coverage you want.
What does crushed ice mean in cushion moissanite?
“Crushed ice” is an informal description for a facet appearance consisting of numerous small, fragmented reflections rather than larger, clearly defined flashes. It is an appearance rather than an official gemstone grade.
What is the difference between cushion and radiant moissanite?
Radiant moissanite generally has straighter sides and cropped corners. Cushion moissanite has rounded corners and softer sides. Both can have square or elongated proportions and brilliant-style faceting.
What is the difference between cushion and princess moissanite?
Princess moissanite typically has straight sides and four sharp corners. Cushion moissanite has rounded corners and a softer square or rectangular outline.
Do elongated cushion moissanites look larger?
Elongated cushions can provide greater vertical finger coverage because their face-up area extends farther along the finger. Actual visible size depends on the individual stone's dimensions and proportions rather than shape or equivalent carat weight alone.
What setting is best for cushion moissanite?
Cushion moissanite works with solitaire, pavé, hidden halo, halo, three-stone and bezel settings. The best setting depends on whether you want to emphasize the center stone or add additional accent stones and detail.
