Blue Nile and James Allen are two of the top online retailers for round cut rings. Get to know their history and products below:

Blue Nile

Blue Nile is one of the top online vendors of engagement rings and other fine jewelry. The company is currently handled by Mark Vadon, Blue Nile’s founder and executive chairman. His jewelry business started in 1999 after getting frustrated while searching for the perfect engagement ring.

Vadon discovered that many jewelry buyers are often overwhelmed by traditional jewelry shopping, especially in physical jewelry stores. Later on, he acquired a diamond-selling website and built a new online jewelry brand called Blue Nile.

The company’s mission is to innovate jewelry shopping by providing quality diamonds and jewelry at the best deals and compelling values. Today, Blue Nile offers a user-friendly online experience by providing comprehensive informational materials, allowing customers to shop at their own pace.

Blue Nile has a massive online inventory of GIA-certified diamonds and jewelry at competitive prices below traditional retail. All their jewelry pieces come with unique designs and quality standards.

James Allen

Established in 2006, James Allen is one of the pioneer jewelry brands that entirely transformed the jewelry shopping experience. A couple initially handled the website under the name of dirtcheapdiamonds.com in 1998.

By 2005, the small jewelry business went through a major rebranding after collaborating with an e-commerce platform called R2Net.

Features to Consider When Buying Round Cut Rings (Buyer’s Guide)

Round-cut stones give off a traditional element to any engagement ring. However, you can add more flair to it by incorporating a stylish ring setting, precious metal, and unique design.

The beauty of a round cut ring lies in its versatility. It looks gorgeous in any setting, regardless of your style and budget. Get to known the five popular ring settings when picking a round cut ring.

Diamond Solitaire

The classic solitaire is the most popular setting for round cut diamond rings. Although jewelry trends come and go, the solitaire setting is a timeless style that never goes out of style. What makes it great is that it places the center stone as the focus of attention. That is why you need to pick a good quality stone to bring out its beauty and brilliance.

Pavé Settings

For those who love everything sparkly and shiny, a pavé setting is an excellent choice. It delivers a feeling of elegance and luxury to the wearer. A ring’s surface is covered in tiny accent diamonds, creating a continuous and consistent glitter effect.

Instead of relying on a single round cut diamond in a solitaire setting, you have an entire row of small diamonds that sparkle at every angle. The only drawback is that this ring setting is difficult to resize. You can avoid this by having accent diamonds go halfway across the shank on either side instead of going around the band.

Halo Setting

The halo setting has earned its popularity due to its ability to enhance a center stone’s brilliance and beauty. In this setting, a round cut stone is wholly enclosed and surrounded by tiny pavé-set diamonds. It gives a gorgeous frame to the center stone, making it appear larger than it already is. This setting works great for those who love vintage-inspired rings. There is also a double halo setting for a truly fancy style.

Bezel Setting

Bezel settings come with a very contemporary look and feel. Among all settings, the bezel does a great job securing the center stone as it prevents it from falling off. It also brings all the attention to the round cut stone. This setting is the best choice for those who lead an active lifestyle. 

A bezel setting appears as a thin metal rim that elegantly wraps itself around the center-stone. It is the highest form of protection for your stone without compromising its beauty. You can also pick between a full or partial bezel setting. Full bezels frame the entire stone, while partial bezels cover only both sides of the stone. The main advantage of a partial bezel is that it provides profile views and an easier cleaning process. 

Cathedral Setting

This setting is the most classic and elegant choice for round cut rings. It uses metal arches to hold the center stone while making it appear larger. It is also unique and a very secure setting for your diamonds or gemstones. The main drawback of this setting is that it can easily catch on clothes and other objects.


Conclusion

Round cut rings are indeed one of the most beautiful jewelry pieces that offer outstanding brilliance and sparkle. They provide incredible flexibility and versatility, where you can set them in any setting and style. They are also great at hiding flaws and inclusions.

This buying guide has listed the best round cut rings from Blue Nile and James Allen. Among all the most stunning and interesting styles, the Riviera Pavé Sapphire Eternity Ring by Blue Nile is the top pick for the best round cut ring.

A Blue Nile favorite, this gorgeous ring features a single row of medium dark blue sapphire stones set in 18k white gold. This ring is available in other colored gemstones, such as amethyst, aquamarine, blue topaz, pink sapphire, ruby, and yellow sapphire. Blue Nile also offers stacked rings in different styles to match them with your bridal rings.

FAQs (Frequently Asked Questions)

What’s great about round cut rings?

Any round cut ring is known for offering the most blinding sparkle for your diamonds or gemstones, especially if it has been cut well. No other shape can compete with the brilliance, sparkle, and fire of a well-cut round stone. Its optical performance of the reflected light allows the stone to appear large, enhance its color, hide inclusions and flaws, and make your ring much more impressive. 

Since the round cut is a very popular shape, diamond suppliers prioritize round cut diamonds, meaning you have bigger options to choose from. 

Why are round diamonds easy to compare?

Round brilliants are the easiest diamond shape to buy as they are subjected to evaluations under diamond laboratories. They are the only shape given with a cut grading, which means you can guarantee a diamond’s quality before buying. 

A cut grading is an essential factor to identify how impressive and how sparkly a diamond stone is. When buying a round cut stone online, retailers allow you to sort the loose stones by cut grade. This way, you can eliminate really poor stones that will not bring out the most sparkle.

What are the drawbacks of round cut rings?

One of the main drawbacks of round cut rings is that they are the most expensive among all diamond cuts. The stone itself is always considerably more expensive than other shapes of the equivalent quality and shape. The reason behind this is wastage, popularity, and labor intensity.

Creating a round shape requires chipping off corners to create a perfect round brilliant shape. It often results in plenty of wastage and particles to be thrown away. Second, since round cuts are one of the most versatile diamond shapes, many jewelry buyers are willing to pay a premium. That is why retailers offer them at skyrocketing prices. Lastly, a round cut stone requires a skilled artisan to ensure that the size and angles are well-cut and correct.
