Cushion and radiant cuts are two popular diamond shapes, each offering distinct light performance, style, and value. Here’s a quick breakdown to help you decide:
- Cushion Cut: Known for its soft, rounded edges and vintage charm, it emphasizes "fire" (colored light reflections) with broader light flashes. It’s ideal for romantic, timeless designs and offers good value (about 25% less than round diamonds). However, it can show color and inclusions more prominently.
- Radiant Cut: Combines modern brilliance with sharp sparkle, thanks to its 70 precise facets. It hides inclusions well, appears larger face-up, and costs 25–30% less than round diamonds. Best for sleek, contemporary styles but may show body color more easily.

Choose cushion cuts for a softer, vintage-inspired look and radiant cuts for a modern, sharp sparkle. Both cuts offer excellent value and unique charm.
Cushion Cut Diamonds: Basic Features
Cushion Cut Basics
The cushion cut is known for its square shape with gently rounded corners, offering a mix of classic and modern aesthetics. This cut comes in a variety of styles, each differing in appearance and how they reflect light. Common options include cushion modified brilliant (available in crushed ice and non-crushed ice styles), cushion brilliant (sometimes with hearts and arrows patterns), and the old mine brilliant cut.
Typically, modern cushion cuts have 58 facets. This design gives them a softer, romantic vibe compared to sharper cuts, making them a popular choice for vintage-style jewelry. Let’s take a closer look at how these facets affect the way light interacts with the diamond.
Light Behavior and Facets
The way cushion cut diamonds reflect light depends heavily on their faceting pattern. Here’s a breakdown of how different variations perform:
| Cushion Cut Type | Light Reflection Style | Spread Size | Price Range |
|---|---|---|---|
| Crushed Ice | Scattered reflections | Standard | Lowest |
| Non-crushed Ice | Broader light flashes | ~6% larger | Mid-range |
| Cushion Brilliant | High brilliance | ~10% larger | Higher-end |
| Old Mine Cut | Unique light flashes | Varies | Most expensive |
The non-crushed ice cushion modified brilliant has four main pavilion facets that extend to the corners, creating broader flashes of light. On the other hand, the crushed ice style features numerous small facets, resulting in a sparkling, diamond-dust effect.
"A cushion cut diamond cannot be bought by its certificate and specifications alone. You need to see how the diamond is cut, either with pictures and videos or in-person. A cushion modified hybrid, cushion brilliant, hearts and arrows, or old mine brilliant faceting pattern gives you the best chance of maximizing light performance." – Diamond Screener
Cushion Cut: Strengths and Limitations
Cushion cut diamonds come with both advantages and drawbacks:
Strengths:
- Known for excellent fire (colored light reflections), often surpassing other cuts.
- Rounded edges enhance durability and give it a vintage charm.
- Offers great value, costing roughly 25% less than round diamonds of similar quality.
Limitations:
- Tends to show color more prominently (H grade or better recommended for white gold settings).
- Deeper cut design can make the diamond appear smaller face-up.
- Open table design makes inclusions easier to spot.
Experts suggest focusing on specific proportions for the best results: a depth and table size under 70%. For example, a 1-carat cushion cut diamond with H color and SI1 clarity is typically priced around $3,500, offering excellent value compared to other premium diamond cuts.
Diamond Face-Off: Cushion VS Radiant Cut Diamonds
Radiant Cut Diamonds: Key Features
Let’s dive deeper into the radiant cut diamond, focusing on its design and how it achieves its stunning sparkle.
Radiant Cut Basics
The radiant cut, introduced by Henry Grossbard in 1977, changed the way diamonds were cut. It combines a square or rectangular shape with beveled corners, merging elements of the emerald and round brilliant cuts. With 70 facets spread across the crown and pavilion, this design is crafted to reflect light beautifully.
The Gemological Institute of America (GIA) classifies radiant cuts as either "cut-cornered rectangular modified brilliant" or "cut corner square modified brilliant". These diamonds typically feature a length-to-width ratio between 1.00 and 1.50, offering a variety of proportions to suit different tastes.
Now, let’s explore how these facets enhance the diamond’s light performance.
Light Performance and Faceting
The brilliance of the radiant cut lies in its precise faceting. Here’s a quick breakdown of the key parameters that impact its sparkle:
| Parameter | Ideal Range | Effect on Brilliance |
|---|---|---|
| Table % | 61–69% | Best light return |
| Depth % | 61–67% | Maximum fire and sparkle |
| Length-to-Width | 1.00–1.50 | Based on personal preference |
| Total Facets | 70 | Superior light reflection |
These facets create a sharp, defined brilliance that sets the radiant cut apart from other shapes.
"The radiant cut diamond owes its brilliance to the 70 facets found in its pavilion and crown. The precision of each facet offers immense brilliance and fire. The radiant cut’s brilliance is surpassed only by the round brilliant cut."
Every detail in the cut is carefully calibrated to amplify the diamond’s sparkle and overall visual appeal.
Radiant Cut: Strengths and Limitations
The radiant cut has its share of advantages and a few drawbacks. Here’s what you need to know:
Strengths:
- Exceptional brilliance, rivaling round brilliants
- Beveled corners add durability
- Costs 25–30% less than similar round diamonds
- Appears larger face-up compared to other shapes
- Effectively hides inclusions
Limitations:
- Tends to show body color more easily
- Limited availability, accounting for just 2% of diamond sales
- No standardized GIA cut grades
- Poorly cut stones may exhibit a bow-tie effect
For the best results, aim for an H color grade or better to ensure a whiter appearance. A high-quality 1-carat radiant cut diamond can cost around $2,900. For instance, James Allen offers a 1.01-carat, VS1 clarity, H color radiant cut for $3,920, while a comparable round brilliant costs $6,130.

Direct Comparison: Cushion vs. Radiant
Visual Differences
Cushion and radiant cuts stand apart in their facet design and how they reflect light. Radiant cuts are known for their sharp, modern sparkle, created by 70 facets that produce frequent, smaller reflections. On the other hand, cushion cuts deliver broader light flashes and a fiery brilliance that feels more classic and romantic.
| Characteristic | Cushion Cut | Radiant Cut |
|---|---|---|
| Light Pattern | Broader flashes with more fire | Smaller, frequent sparkles |
| Edge Style | Rounded, soft corners | Straight, beveled corners |
| Visual Effect | Vintage, romantic appearance | Modern, sleek brilliance |
| Facet Size | Larger facets | Smaller, more numerous facets |
What Affects Brilliance
Several factors determine how these cuts reflect light and achieve brilliance:
| Factor | Impact on Performance |
|---|---|
| Facet Pattern | Shapes light return and fire characteristics |
| Cut Quality | Plays the biggest role in overall sparkle |
| Pavilion Design | Influences the size and intensity of flashes |
Cushion cuts can exhibit either a "crushed ice" or "non-crushed ice" look, which greatly impacts their light performance. Radiant cuts with a "long mains" pavilion pattern are especially effective at maximizing brilliance. These technical design choices create visible differences, as confirmed by industry experts.
Expert Analysis
Experts emphasize how facet design and cut quality shape the visual appeal of each diamond. These elements work together to define the sparkle and overall look of the stone.
"Often times, the dark parts of the pattern you see in a diamond are a reflection of your face, or the camera – if you’re looking at a photograph"
Radiant cuts are often praised for their ability to hide inclusions and body color, making them more forgiving with lower clarity grades. In contrast, cushion cuts, with their larger facets, make clarity issues more noticeable, requiring higher clarity grades. Some cushion cuts have been refined with brilliant-style facets to enhance sparkle while maintaining their signature fire.
"Diamonds and jewelry are very personal. People buy jewelry for themselves or receive it as a gift for a specific reason, often to celebrate a special occasion. Choose what you like and what looks best in your opinion. Then, enjoy the adventure of learning all the different appearances your diamond can have."
How to Choose Between Cuts
Deciding between cushion and radiant cuts depends on how each style fits your ring design and personal preferences. Let’s break it down.
Design and Look
Cushion cuts are perfect for a classic, vintage-inspired look with soft, rounded edges. On the other hand, radiant cuts bring a modern flair and pair well with various accents:
- Work beautifully with round or square accent stones.
- Match baguette or half-moon side stones.
- Look stunning in trendy two-tone metal settings.
For radiant cuts, rectangular shapes typically shine with a 1.20–1.30 ratio, while square versions look best around 1.05.
Price Comparison
Both cuts are more affordable than traditional round brilliants, with competitive pricing between them:
| Diamond Specifications | Cushion Cut | Radiant Cut |
|---|---|---|
| 1 carat, J color, Excellent cut | $2,050 | $2,479 |
| 1 carat, H color, VS2 clarity | $3,000+ | $3,000+ |
This pricing table can help you weigh your options based on your budget and preferences.
Making Your Decision
Here’s a quick comparison of key factors to guide your choice:
| Factor | Cushion Cut | Radiant Cut |
|---|---|---|
