What Is Cushion Modified Diamond?

By Delaney Pitts

Diamonds are known for their brilliance, but the way they reflect light depends on their cut and faceting style. If you're exploring cushion-cut diamonds, you may have come across the term cushion modified diamond and wondered what makes it different from a standard cushion cut.

Is it a better choice for an engagement ring? How does it compare to round or radiant cuts? And does its unique faceting affect its value?

In this guide, we’ll cover everything you need to know about cushion modified diamonds, including their characteristics, comparisons, sparkle, best settings, and buying considerations.

What Is a Cushion Modified Diamond?

A cushion modified diamond is a variation of the cushion cut that features a slightly different facet arrangement on the pavilion (the lower portion of the diamond). This modification enhances the scattered light reflection, creating a unique "crushed ice" sparkle instead of the large, structured flashes seen in classic cushion-cut diamonds.

Key Features of a Cushion Modified Diamond

Soft square or rectangular shape with rounded edges
Unique "crushed ice" sparkle instead of larger light flashes
More facets than a classic cushion cut, creating a high-energy shimmer
Can appear larger per carat compared to some other cuts
Works well in modern and vintage-inspired engagement ring settings

If you're drawn to diamonds with lively, shimmering sparkle, a cushion modified diamond could be the perfect choice.

Cushion Modified vs. Classic Cushion Cut: What’s the Difference?

Both cushion modified and classic cushion diamonds have the same overall shape, but they differ in their faceting patterns, which impacts how they reflect light.

1. Sparkle & Light Performance

Cushion Modified Diamond: Features a "crushed ice" sparkle, where light scatters in many directions, creating a glittering effect.
Classic Cushion Diamond: Has larger, more structured facets that produce distinct flashes of light, similar to antique diamonds.

2. Brilliance & Fire

Cushion modified diamonds have a high-energy, consistent sparkle across the entire surface.
Classic cushion cuts display more separated flashes of brilliance and fire (colored light dispersion).

3. Appearance & Facet Structure

Cushion modified diamonds have more facets, which break up the light into smaller, more numerous reflections.
Classic cushion cuts have fewer, larger facets, producing a softer, vintage-inspired sparkle.

Which One Is Better?

This depends on personal preference. If you love lively, shimmering diamonds with constant sparkle, a cushion modified diamond is ideal. If you prefer bold, defined flashes of light, a classic cushion cut may be the better fit.

How Does a Cushion Modified Diamond Compare to Other Cuts?

If you’re choosing between a cushion modified diamond and another cut, here’s how it compares to popular alternatives:

Cushion Modified vs. Round Brilliant Diamond

Round diamonds maximize brilliance and fire with their perfectly symmetrical cut.
Cushion modified diamonds offer a unique sparkle, often at a lower price per carat.
Which to choose? If you want the most brilliance, go for a round. If you prefer a romantic, soft-edged shape with great sparkle, choose cushion modified.

Cushion Modified vs. Radiant Cut Diamond

Both cuts have a crushed ice effect, but radiant cuts are typically more elongated.
Cushion modified diamonds have a softer, more vintage feel, while radiant cuts are more geometric and modern.
Which to choose? If you want a diamond with angular brilliance, go for a radiant cut. If you prefer a more rounded, romantic look, choose cushion modified.

Buying Guide: Is a Cushion Modified Diamond a Good Choice?

If you’re considering a cushion modified diamond engagement ring or fine jewelry, here are the key factors to keep in mind.

1. Sparkle & Light Performance

Do cushion modified diamonds sparkle more? Yes, but in a different way than round or classic cushion cuts. Their crushed ice effect creates a shimmering, multi-directional sparkle, rather than large flashes of light.

Tip: If you want a diamond that constantly shimmers, a cushion modified cut is an excellent choice.

2. Carat Weight & Size Appearance

Cushion modified diamonds appear larger for their carat weight due to their facet structure and shape.
Elongated cushion modified diamonds can further enhance this effect.

Tip: If you want maximum visual impact, look for a slightly elongated cushion modified diamond.

3. Clarity & Inclusions

Cushion modified diamonds are great at hiding inclusions due to their intricate sparkle pattern.
You can often opt for a VS2 or SI1 clarity without visible flaws.

Tip: If you’re on a budget, consider a lower clarity grade, as the extra facets help mask imperfections.

4. Color Grading

Cushion modified diamonds tend to retain more color than round diamonds.
For a bright white look, choose a G or better color grade.
If you prefer a warmer tone, H-I color diamonds work well, especially in yellow or rose gold settings.

Tip: Platinum or white gold settings enhance a colorless diamond, while yellow or rose gold can balance out warmer color grades.

5. Best Settings for Cushion Modified Diamonds

Cushion modified diamonds are versatile, working well in various engagement ring settings:

Halo settings – Enhances the crushed ice sparkle and makes the center stone appear larger.
Solitaire settings – Showcases the diamond’s brilliance in a classic, elegant style.
Three-stone rings – Adds dimension and extra sparkle.

Tip: If you love maximum brilliance, pair a cushion modified diamond with a diamond-accented band.

Final Thoughts: Is a Cushion Modified Diamond Right for You?

A cushion modified diamond is an excellent choice for those who:

Love the shimmering, crushed ice sparkle over bold flashes of light.
Want a more budget-friendly alternative to a round brilliant diamond.
Prefer a soft, romantic shape that blends vintage and modern appeal.
Are looking for a diamond that appears larger per carat weight.

If you prefer a structured, bold brilliance, you may want to consider a classic cushion cut or a round diamond instead.
