All About Radiant Cut Diamonds

Are you looking for a special kind of diamond? Do you enjoy the scintillation of brilliant cuts but prefer a shape like a step cut? What about something that combines the two? Well, you’re in luck, and in good company. Diamond cutters, in searching for the answer to the same issue we just outlined, developed the radiant cut to answer it. Join us, in this Michael Gabriels article, as we explore radiant cut diamonds, how to choose one, and why they are so special. 

 In the 1970s Henry Gossard combined two kinds of faceting styles to create one of the most popular diamond shapes of all time. Originally patented by Grossbard, demand for radiant cuts has rapidly increased, and has been repeatedly replicated now that the patent has lapsed.


In a Vogue interview, GIA-graduated gemologist Olivia Landau noted that “women who like radiant cuts tend to be bubbly and outgoing,” and that it is a great shape for those who are looking for a sparkle and flash in a rectangular shape.


The radiant cut, a modern classic, has timeless features that will make it fashionable for the foreseeable future. Perhaps that’s why it graces the likes of Drew Barrymore, Jennifer Aniston and Khloe Kardashian. Radiant cut engagement rings, radiant cut diamond rings and other jewelry are all increasingly popular as consumers look for more ways to express their personality, and as they find out that radiant cuts are a more cost-effective option compared to many other cuts. 


What are Radiant Cut Diamonds?


Similarly shaped to emerald cuts, they are square or rectangular with cropped corners, enough to make them octagonal.


A mix of faceting styles, they have the outline of an emerald cut with the sparkle of a brilliant cut. Up to or more than 70 facets scintillate, refract and reflect light producing the “crushed ice” or “crushed glass,” look expected from brilliant cut stones.  


Radiant cuts all fall on a spectrum between squared or elongated (rectangular). Proportions are especially important, since they will directly affect the nature of the light performance within the stone.

Why and How to Buy a Radiant Cut Diamond 


Radiant cuts are less bottom heavy than round cuts or princess and therefore are most cost effective per carat- with more visible diamond on the table than lost deep in the pavilion. Of course, this is not the case for every stone, but as a rule, they can look much larger than round brilliant stones of the same carat size. 


Like some other modified brilliants, radiant cut diamonds have the ability to transform the color of a diamond. Many stones initially of a dark tint show up much lighter, if tinted at all, when cut or re-cut into radiant cuts. 


They also mask some inclusions, unlike emerald cuts, which expose the inside of the diamond and reveal any inclusions or blemishes, however small. Therefore, a radiant cut diamond can appear eye-perfect at a lower clarity rating than an emerald cut diamond. 


Symmetry is definitely a goal with radiant cut diamonds. Make sure to check that the culet is centered, that the sides are parallel, and avoid corners that are uneven. You don’t want them too wide or too narrow.

Ratios & proportions are helpful pieces of information that can give you an idea of the diamond, but not crystal clarity in understanding whether that diamond is right for you. You should always see a stone in person if at all possible. 


It is always best to see the report on a diamond from a third party agency, such as GIA and IGI, used by Michael Gabriels for all of our diamonds. In the report you will find the grades for the 4cs (insert Hyperlink) as well as the proportions and ratios. While proportions and ratios may vary greatly between one diamond and another, it has been our experience that many different combinations can be equally appealing and exciting. That being said, here is a basic guide for what you may want to keep an eye out for:

What are the Best Settings for Radiant Cut Diamond Engagement Rings? 


Solitaire settings are well suited for radiant cuts. Their cropped corners are easy to secure, and are not in as much danger of chipping or fracturing as are the sharp corners of other square cuts. Unless the stone in question has a very thin girdle, you can use delicate prongs to raise the diamond high above the band, allowing for the most amount of diamond to be viewed. 


Pave accents, such as a halo, can add scintillation and make the diamond appear even larger. 


Accent stones such as trilliums, baguettes, and trapezoids compliment the structure of the diamond, while stones with more rounded features, such as round brilliants, ovals, pears or hearts can add a delightful contrast and personality to the ring. 


What are the best jewelry pieces for radiant cut diamonds? 


Aside from engagement rings, radiant cut diamonds are very well suited to a vast array of jewelry pieces and styles. Their elegance and playfulness make them perfect for active wear tennis bracelets or other sports jewelry, since they have no sharp corners or edges to snag. They make beautiful center stones for necklaces and pendants. As earrings, try a pair of drops or dangles with one or more radiant cut diamonds to really wow people. Furthermore, the angular shape of the radiant cut diamond earring will add structure to rounded facial features.

Lab grown diamonds 


Atomically the same, structurally the same, and chemically the same, lab-grown diamonds differ little from their mined cousins. The main difference really is in how they get to market. Lab-grown diamonds take days to weeks to make, after which they are sent to cutters who grind out the polished diamond, which is then evaluated by a third party, and then sold by a retailer to a consumer. Of course there are few more changes of hand than that, but that's basically what happens.

Mined diamonds take millions of years to form and then must be discovered, dug out of the ground, and only then can be sent to cutters and third party evaluations. Diamond producing labs are often found in industrial centers or near large cities where diamond cutting is already established so that there is less expense spent on shipping. Mines do not have that luxury and are largely found in some of the most remote places in the world. Moreover, they use vast amounts of water, energy and resources and can destroy or vastly alter the land upon which they dig. Only operational temporarily, mines shut down when it is no longer economically viable to excavate the ore, sometimes leaving desolation and toxic chemicals held up in tailings pools. Labs that create diamonds use much less water, energy, can be operated in the same place infinitely, and do not destroy the land or the community upon which they reside. 


Especially because of the fewer added costs of machinery, energy, water, land, workers, and multiple long distance shipping, lab-grown diamonds are almost always less expensive than their mined counterparts.
