Radiant cut diamonds combine elegance and brilliance with their modern rectangular or square shapes, accented by their trimmed corners, making them a stunning choice for anyone who loves jewelry. These diamonds have 70 facets that enhance their sparkle while reducing the risk of chipping, so they're perfect for everyday wear. They offer a bold sparkle compared to classic cuts like emerald or round brilliant, and they even make your fingers look longer and more elegant. When choosing a radiant cut, focus on getting the right cut and color because they make the biggest difference in how the diamond looks. Whether you prefer traditional white or colored stones, radiant cuts are super versatile and beloved by celebrities and influencers for their eye-catching appeal.
What Is a Radiant Cut Diamond?
A radiant cut diamond is a rectangular or square-shaped diamond with cut corners, featuring 70 precisely angled facets. Created by Henry Grossbard in 1977, this unique cut combines the elegant shape of an emerald cut with the brilliant-style faceting pattern of a round diamond. The result is a diamond that displays exceptional sparkle while maintaining clean, geometric lines. Unlike emerald cuts, radiant cuts hide inclusions better due to their faceting pattern, making them an excellent choice for diamonds with slight imperfections. Most radiant cuts have a length-to-width ratio between 1.00 (perfectly square) and 1.35 (distinctly rectangular), allowing buyers to choose their preferred shape.
The Radiant Cut: A Closer Look at What Makes It Special
How Radiant Cuts are formed
The brilliant cut diamond is carefully designed with around 70 facets (flat surfaces) that are skillfully cut and positioned to achieve the brilliance of the diamond. Picture these facets as miniature mirrors that catch and bend light in the stone. The top part of the diamond (the crown) has around 25 facets, and the bottom part (the pavilion) has around 40 facets, with some additional ones along the rim.
This clever design creates three unique types of sparkle that you can see:
- Brilliance: The white light bouncing off the diamond so it appears to glow
- Fire: Those rainbow-hued flashes of color that you see when light crosses over it at exactly the right angle
- Scintillation: The flash effect you see when the diamond or your hand is in motion
Why the Radiant Cut Works So Well
The radiant cut isn't just a nice thing to look at - it's even designed to be practical as well:
- Fewer corner chips: Unlike most square cuts, radiant cuts have clipped corners instead of points. This means they're much less likely to chip if you accidentally bang them into something.
- Hides imperfections well: The alignment of all those angles by nature hides small inclusions (small imperfections) within the diamond. Something that can be seen in some other cuts gets lost in a radiant cut.
- Looks good anywhere: Whether you're bathed in strong sunlight, interior lighting, or even low restaurant lighting, radiant cuts look like they hold their sparkle longer than some other cuts.
- Better value: Because of how the cut works with the original rough diamond, less waste is incurred when cutting a radiant cut. This typically translates to you getting more diamonds for your money.

What to Check in a High-Quality Radiant Cut
If you are buying a radiant cut diamond, these are some of the most critical issues to look for:
- Shape: Radiant cuts are square (looks to be a perfect square) or rectangular. Square, check for length-to-width ratio of approximately 1.00 to 1.05. Rectangular, 1.10 to 1.50 is acceptable, depending on how stretched you like.
- Table size: This is the even, flat top of the diamond. Measure for 60-70% of the width of the diamond. Too big or too little, and it won't glint as much.
- Depth: This affects how the light bounces around inside. Generally, you want the overall depth to be 60-70% of the width of the diamond.
- Polish and symmetry: Ask for "Good" or better grades on each. This will ensure all those angles are lined up and polished enough to reflect light. Don't forget, most importantly of all, what the diamond looks like to your eye. Numbers are great references, but when a diamond sparkles stunningly and you love the way it looks, that's truly the biggest thing.
Diamond Cut Comparison: How Radiant Cuts Stack Up Against Round and Emerald
When choosing the perfect diamond, understanding how different cuts compare can make all the difference in finding your ideal stone. This comparison focuses on how the radiant cut stands against two of the most popular diamond cuts: the classic emerald cut and the traditional round brilliant. Each cut offers unique characteristics that appeal to different preferences and priorities, from brilliance to value.
Radiant Cut vs. Emerald Cut
The radiant and emerald cuts might share a similar shape, but their characteristics create distinctly different visual experiences. Let's explore their key differences:
| Feature | Radiant Cut | Emerald Cut |
| Facet Count | 70 brilliant-style facets | 50-58 step-cut facets |
| Light Effect | Intense sparkle and fire | "Hall of mirrors" effect |
| Inclusion Visibility | Effectively masks inclusions | More visible inclusions |
| Visual Style | Dynamic and brilliant | Clean and sophisticated |
| Best For | Maximum sparkle seekers | Clarity and elegance lovers |
Go with radiant if you want more sparkle in a modern shape, or choose emerald if you love that classic, step-cut elegance. Both are beautiful - it's really about the look that catches your eye.

Radiant Cut vs. Round Brilliant Cut
While the round brilliant is often considered the standard for diamond cuts, the radiant cut offers compelling advantages that make it an attractive modern choice. Here's how they compare:
| Characteristic | Radiant Cut | Round Brilliant |
| Light Return | 85-90% | 93% |
| Face-Up Size | Larger appearance | Standard appearance |
| Price per Carat | 10-15% less | Premium pricing |
| Setting Versatility | Good | Excellent |
| Visual Impact | Modern and unique | Classic and traditional |
| Value Proposition | Better price per carat | Traditional premium |
In short, pick the round brilliant if you want the absolute most sparkle and don't mind paying more. Choose radiant if you want similar sparkle with a unique shape and better value for your money.

Why Choose a Radiant Cut Diamond?
Looking at all the options? Here's why the radiant cut might be your perfect match.
This Diamond Sparkles a Lot
With its 70 precisely-cut facets, the radiant cut is a sparkle powerhouse. Its unique facet pattern creates amazing fire and brilliance, ranking just behind the round brilliant in light performance. Even in low light, these diamonds maintain their eye-catching sparkle.
This Shape Makes Your Fingers Look Better
The rectangular shape creates an illusion of longer, slender fingers - a bonus for any hand size. Plus, radiants typically look 10-15% larger than round diamonds of the same carat weight, thanks to their larger face-up area. This means you can get a more impressive-looking diamond without spending more on higher carat weight.
This Diamond Won't Break Easily
Unlike sharp-cornered cuts like the princess, radiant's beveled corners make it less likely to chip or snag. This means your diamond can handle daily wear better, perfect if you're active or work with your hands.
You'll Pay Less Than for Round Diamonds
Looking to save some money? Radiant cuts typically cost 20-25% less than round brilliants of the same quality. You can either pocket the savings or use them to get a larger stone.
This Shape Looks Good in Any Ring Style
Whether you're into vintage looks or modern designs, radiant cuts fit right in. Their clean lines work great in solitaire rings, look stunning with side stones, and can even rock a halo setting.
Small Flaws Are Hard to See in This Diamond
The complex facet pattern does more than create sparkle - it's also great at masking small inclusions. This means you can often go with a slightly lower clarity grade without any visible difference, saving you even more money.
Why This Diamond Sparkles So Much
A radiant diamond has many flat surfaces (called facets) that work like tiny mirrors. When light hits these surfaces, it bounces around inside the diamond before coming back to your eyes as sparkle. Think of it like a room full of mirrors reflecting light in different directions.
Getting the Right Shape Matters
Just like a badly aimed mirror won't reflect light properly, a diamond needs to be cut in the right way to sparkle its best. The diamond cutter needs to make sure:
- All the angles are even
- The surfaces are polished smooth
- The overall shape is balanced
When these factors are right, light travels through the diamond in a way that creates the most sparkle. If the cut is uneven or the angles are wrong, some areas might look darker or duller than others.
What to Look For:
- Even sparkle across the whole diamond
- No dark spots or dull areas
- Bright flashes when you move the diamond
- Clear, crisp reflections
This is why it's important to look at a diamond from different angles before buying - you want to make sure it sparkles well from every direction.

How to Style Your Radiant Cut Diamonds: Tips and Tricks for Every Occasion
Your radiant cut diamond is versatile and can work for almost any occasion. Here's how to make it look great and keep it safe while you wear it.
Everyday Wear (Work, Running Errands, Casual Days)
Best settings for daily life:
- Four-prong setting - most secure and shows off the stone well
- Bezel setting - completely surrounds the diamond for extra protection
- White gold or platinum - won't scratch as easily as yellow gold
Key tip: Keep other jewelry simple when wearing your radiant cut. Let it be the star of the show.
What works well together:
- Small stud earrings (diamond or pearl)
- Thin chain necklace Simple watch or tennis bracelet
Special Occasions (Dinners, Parties, Date Nights)
Go bolder with confidence:
- Pair with geometric jewelry - the angular shape of your radiant cut looks great with other geometric pieces
- Add a matching necklace - but keep it smaller than your ring
- Choose complementary earrings - dangly or chandelier styles work well
Golden rule: If your ring is big and sparkly, keep everything else smaller. If your ring is more subtle, you can add more dramatic pieces.
Professional Settings (Office, Meetings, Interviews)
Keep it polished but not flashy:
- Stick to classic combinations - your radiant cut ring plus simple studs
- Choose neutral metals - white gold, platinum, or silver tones work best
- Avoid stacking multiple rings - one beautiful ring is perfect for work
Safe choices that always work:
- Pearl or small diamond studs
- Thin gold or silver chain
- Classic watch with leather or metal band
Choosing the Right Metal (This Counts Too)
White Gold or Platinum:
They bleach and light up your diamond so that it appears as though they are heightening the glitter. They go with everything you put on, including tiny black dresses and holiday attire. This is your best bet if you already have a great deal of silver jewelry or prefer a cool, modern appearance.
Yellow Gold:
Yellow gold gives your bright cut a timeless, warm appearance that won't ever go out of style. It is perfect for traditional or vintage looks and will probably give the whole piece an air of being more vintage. This is especially great if you have warm skin or most of your other jewelry is already gold.
Rose Gold:
Rose gold creates a trendy, bohemian look that's unique and feminine. Surprisingly, it works on most skin tones and presents a new twist to the classic diamond ring. Choose this if you love being a bit different or if you're drawn to trendy, Instagram-friendly items.
Quick Styling Do's and Don'ts
DO:
- Mix metals if they're in the same piece (like a two-tone setting)
- Consider your skin tone when choosing metals
- Think about your lifestyle - active people need more secure settings
DON'T:
- Wear your radiant cut with other large statement rings on the same hand
- Mix too many different metals in one outfit
- Forget that your daily activities affect what settings work best
Bottom line: Your radiant cut diamond is meant to be worn and enjoyed. Pick styles that make you feel confident and fit your real life, not just special occasions.
How to Care for Your Radiant Cut Diamond
Correct care of your excellent cut diamond ensures its brilliance and value for the long term. Regular care and careful handling protect your investment, with your diamond appearing at its finest year after year.
Step 1: Start with Every-Day Gentle Care
The number one thing you can do is treat your diamond gently on a daily basis. When you're putting it on or taking it off, hold the band and not the stone itself. Your own skin oils will make the diamond look dull, and rough handling will loosen the setting over time. Just treat your diamond like something valuable that needs to be taken care of.
Step 2: Clean Your Diamond at Home on a Regular Basis
This is an easy method of cleaning your diamond at home. Fill a small bowl with warm water and add a few drops of dish soap to it. Soak your diamond in the soapy water for 10-15 minutes, and then use a soft-bristle toothbrush to rub around the stone and the metal parts. Make sure to clean the back of the diamond where oils and grime love to nestle. Gently run it under warm water and dry it off with a soft, clean cloth to get that sparkle back.
Step 3: Know When to Remove Your Diamond
Take off your diamond prior to participating in specific activities that could damage it. Don't put it on if you're working out, swimming (especially in pools with chlorine), scrubbing the house with abrasive cleaners, gardening, or doing any type of physical labor. Diamonds are very, very hard, but the metal surrounding them can be ruined, and other things will scratch the band. It's just easier to take it off and put it in a safe place.
Step 4: Properly Store Your Diamond
When you're not wearing your diamond, keep it stored. A jewel box lined with a soft substance is great, or you can wrap it in a soft substance. Don't throw it in your jewelry drawer with the rest of your things since diamonds scratch other stones and metal. When you travel, put it in a soft jewelry bag and have the diamond lying flat so that there isn't strange pressure on it.
Step 5: Inspect Your Diamond Monthly
Each month, examine your diamond in bright light. Ensure the tiny metal prongs holding your stone are still tight and not twisted. Try to rock the gemstone with your finger – it should not budge at all. Check the band for cracks, dings, or wear areas. This monthly check maintains your consciousness of minor problems before they become gigantic, costly ones.
Step 6: Have Professional Maintenance
Have your diamond professionally cleaned and inspected every half year at a jeweler. They know the proper tools to clean it and can also inspect if everything is secure. Have them do a complete checkup annually, wherein they examine all the prongs, secure loose stones, and confirm everything is fine. Just think about taking your car in for an oil change – it keeps the system in working order.
Step 7: Act Quickly on Any Problems
If you think the stone is loose, find a bent prong, or have any other problem, take it off right away and visit a jeweler promptly. Avoid trying to fix it yourself because you might do more harm than good. Even a loose stone can easily become a lost diamond, so getting help in a hurry really makes a difference when something is wrong.
Step 8: Maintain Important Records
Maintain a folder with your diamond's paperwork, like the one it came with, your insurance papers, and pictures of what it looks like. Keep your insurance policy up to date with what your diamond is now worth at all times, and record every time you get it cleaned or repaired. These papers are extremely useful if you ever have to file an insurance claim, and they're convenient for future repairs or if you ever decide to sell it. Just keep them in a safe location away from the jewelry itself.
