From a subtle and reasonable diamond, let us jump to a more expensive one. Blue Nile’s 1.57-Carat Radiant Cut Diamond has promising features that you can rarely find. They also justify the five-digit price that comes with this item.
4Cs affect a diamond’s valuation. If a diamond has a heavier carat weight and higher ratings in cut, color, and clarity, you should not be surprised if the price jacks up.
This Blue Nile diamond has a color D grade and Internally Flawless clarity. They are the highest degrees a diamond can get from a certifying body, like GIA. It means that the diamond is colorless and spotless; therefore, it is rarer and more valuable.
The thick girdle quality adds to the diamond’s durability. Hence, you can pair it with any settings, and it will always end up looking sleek and classy. However, this item emits a strong blue fluorescence, making it look cloudier than it should be.
Nevertheless, this diamond has that radiant and sophisticated glow perfect for high-end occasions. Anyone who receives a gift like this is indeed the lucky girl that everyone will envy.

More than that, it has little to no blemishes. Thus, you will enjoy how smooth and beautiful it looks from afar and up close. Indeed, comparing it with others will only highlight its radiant and flawless appearance.
As flattering as it may look, the price is your biggest enemy in this diamond. Lucky are those who can afford it, but the company also offers installment payments if you cannot pay it on a one-time basis.

These qualities may be impressive, but they failed to stand out from the rest. Despite its near-colorless grade, the yellowish tone is still apparent. It may look a little hazy, but not too noticeable. Nevertheless, they do not make the diamond’s worth any less valuable.

History of Radiant-Cut Diamonds
Radiant-cut diamonds became available in the market later than the other diamond varieties. Henry Grossbard is the name you should remember when it comes to this valuable piece.
He apprenticed with a diamantaire during World War II and later became a master cutter. In 1976, Henry invented a hybrid cutting style that gave birth to the radiant-cut design. From then on, square-cut diamonds’ brilliance became a competitive rival of more popular varieties, like round and oval-cut pieces.
A year later, Henry established the Radiant Cut Diamond Company (RCDC) to market his invention. Unfortunately, his success halted when he left the world in 2005 in a hit-and-run accident. His children took over the business afterward.
Innovation is the root of the radiant-cut diamond’s invention. Before 1976, step-cut edges and square diamonds are less appealing and fall to the pyramid’s bottom. Today, more and more men and women are showing interest in owning a piece of jewelry with this design.
Lab-Grown Diamonds vs. Naturally Grown Diamonds
You noticed that our top recommended diamond in this article is lab-grown. While we mentioned a piece of information about this term a while ago, you will be learning more about it in this section.
The majority of radiant-cut diamonds are lab-grown because it is a result of a hybrid process. Thus, it will help if you learn more about the term to improve your knowledge of diamonds.
Lab-grown diamonds, also called synthetic diamonds, give mixed feelings towards consumers. We want to correct several misconceptions because this piece is as precious as naturally grown ones. It even has benefits that you cannot acquire from the latter.
First Misconception: Lab-Grown Diamonds Are Fake
No, they are not fake diamonds. As its name implies, the diamond results from mixing several elements found in a naturally grown stone inside a laboratory. They technically have the same components, and they radiate similar sparkle.
Color and clarity are not even relevant issues to lab-grown diamonds because gemologists grade them similarly to the naturally grown pieces.
Second Misconception: Lab-Grown Diamonds Are Softer and Fragile
We hate to break it to you, but this perception is wrong. The answer lies to the first misconception. Since a lab-grown diamond has the same components as naturally grown diamonds, both have similar toughness and strength.
None of them are softer than the other.
Third Misconception: Lab-Grown Diamonds and Cubic Zirconia Are Similar
Cubic Zirconia is a diamond-like stone invented in 1976 at a laboratory. It may look flawless and colorless, but it has less fire and brilliance than a real diamond. Plus, it is also softer and gets scratches easily since it is not as tough as legitimate diamonds.
Thus, Lab-Grown Diamonds are not similar to Cubic Zirconia. The former is a legitimate piece, while the latter is only a low-cost imitation.
What Makes Lab-Grown Diamonds Better Than Naturally Grown Diamonds?
As the world modernizes, the manner of producing gemstones also evolved. We now have better technologies that help us produce more without hurting the environment. This idea goes with lab-grown diamonds.
Mining diamonds is a great contributor to pollution and environmental degradation. With lab-grown diamonds, mining becomes less convenient. With a more cost-effective way of producing diamonds, its market price is also lower than mined ones. Thus, you are simultaneously helping the environment and saving more money.
However, this process does have a drawback. It increases the value of mined diamonds because of the rarity in the market. Plus, growing diamonds in a laboratory is expensive, demanding, and a tedious pursuit. The sustainability of this process is quite questionable.
Terms to Keep in Mind When Purchasing a Radiant-Cut Diamond – A Buyer’s Guide
You now learned almost everything that you need to know about radiant-cut diamonds. The last portion that we want to impart is the terminologies you should always remember when buying one. These terms will help you breakdown a diamond’s quality so that you can quantify if the price is right for your chosen piece.
‘Cut’ is the first C in the infamous diamond term ‘4Cs.’ It represents symmetry, dimensions, and reflective qualities. Round, princess-cut, and cushion-cut diamonds are examples of varieties that follows a standard cut grading.
The Gemological Institute of America (GIA) identifies to which grade does a diamond belongs. It can be Ideal, Very Good, or Good. Blue Nile’s highest standard is Astor Ideal.
However, this grading does not apply to all varieties. Oval-cut, pear-cut, and radiant-cut diamonds are more difficult to quantify. Thus, their measurements become subjective, depending on which setting or ornament you will use the diamond.
Naturally, diamonds have yellow pigments because of the presence of Nitrogen. However, some rare items have near-colorless to colorless features. Thus, GIA grades the diamonds based on the faintness of the color.
Most jewelry shops do not sell pieces with grades L to Z because their color is unpleasantly visible. The least grade accepted in James Allen and Blue Nile is grade K. It still looks yellowish, but it is beautiful when paired with copper and rose gold bands.
The highest and purest color grade is D, and the most valuable range for money are the near-colorless group from G to J. Like cut grade, higher color grades mean more expensive price.
The clarity of a diamond is another crucial aspect when assessing it. Most, if not all, customers prefer flawless jewelry because it emits better brilliance as light passes through it. Why would you spend a lot of dollars on a stone that does not sparkle?
Thus, you must check the clarity rating of a diamond. It is natural for it to have blemishes, but the key here is finding a piece with the least flaws. Its grading system is as follows in ascending order:
- Included 1
- Included 2 and 3
- Slightly Included 1 and 2
- Very Slightly Included 1 and 2
- Very Very Slightly Included 1 and 2
- Flawless to Internally Flawless
Most items available in the market range from SI1 to VVS2 because they have the best market value. They already look eye-clean from a wearer’s perspective. Thus, spending more for the highest grade becomes impractical.
However, some still prefer an Internally Flawless piece since it’s the rarest of them all.
Carat weight is the physical weight of a diamond. Thus, the higher number of carats, the heavier a diamond is. The heavier it weighs, the more precious it becomes.
However, it does not necessarily mean that a 1.0-ct round diamond has the same size as a 1.0ct radiant-cut diamond. The latter looks bigger than the former because it has a wider surface area. Thus, it tricks the mind to believe that a radiant-cut is larger than round pieces.
They still have the same weight, but not the same symmetries.
These are the primary factors that you should be extra careful when buying a diamond. We want you to get a premium item at best possible value. Thus, knowing these terms is a huge help for your assessments.
You and your recipient’s preference should be the top priority when buying a diamond. A radiant-cut is one of the many options available in the market. If you go for this piece, you should get familiar with terms that will help you decide which brand and item to choose.
Their carat weight, color, clarity, and cut dictate the amount equivalent to its value. The list may be long for this variety, but we highly recommend that you pick James Allen’s Lab-Created 1.28 Carat Radiant Diamond. Apart from it being cost-effective, it has the same premium quality as naturally grown diamonds.
However, you still have the option to go for a lower or a higher price. What matters is that you feel satisfied as a customer. In the end, a diamond will always be a precious and timeless piece regardless of its price and shape.
