Best Brands for 1 Carat Diamond Rings

Today, there is no need to visit every physical store and deal with every salesperson. You are far better served when shopping for jewelry online as online retailers allow you to shop at your own pace, and more importantly, no pressure.

This buying guide has highlighted two of the top online dealers of diamond rings: Blue Nile and James Allen. Now that you have discovered some of their great finds, it’s time to discover who they are as an online jewelry brand. 

Blue Nile

Blue Nile started as an online jewelry business in 1999 with a vision to modernize the diamond and jewelry business. While searching for the perfect engagement ring, Mark Vadon discovered an existing need to change the jewelry shopping experience.

Following an online business model, Mark obtained Internet Diamonds and transformed it by building a new jewelry brand called Blue Nile. The company used a new strategy by introducing a convenient way of shopping for a diamond engagement ring. The idea was quickly embodied throughout Blue Nile’s global reputation as a premier specialty retailer of diamond and jewelry.

Blue Nile adheres to the customer-first philosophy by providing its clients with more quality choices, professional customer services, and straightforward information. They also hired skilled diamond experts and jewelry staff to help them serve their growing consumer base. 

Today, Blue Nile boasts of its premium quality products at the best value and competitive prices while enjoying an empowering shopping experience. Some of their products and services include fine jewelry, fancy colored diamonds, diamond consultants, proprietary diamond search, and customizable diamond and jewelry function. 

James Allen

Establish in 2006, James Allen has changed the way people shop for diamond and fine jewelry. Led by a husband and wife team, it started as a small online jewelry business in 1998 called dirtcheapdiamonds.com. 

A few years later, an e-commerce platform called R2Net merged with the company and later rebranded as JamesAllen.com. Since then, James Allen started to adopt a new business strategy, especially on how they market their jewelry and diamonds. 

The company used a more sophisticated image, offering diamonds and fine jewelry accredited by well-known jewelry authorities. It wasn’t too long when James Allen quickly climbed to the top of the online jewelry industry by becoming the leading jewelry brand in terms of sales.

Features to Consider When Buying 1 Carat Diamond Rings (Buyer’s Guide)

The main goal of buying a diamond ring is to find brilliant, premium quality diamonds at the best price. You should never pay more than you should, especially when buying a diamond ring. Here are some of the key features to consider when shopping for diamonds.

Shape

The shopping process always starts with finding the best diamond shape that suits you or your partner’s preference. Round brilliants are a popular choice for engagement rings since their cut gives off the best brilliance. You can also pick from other cuts, such as princess, baguette, cushion, or oval. 

Carat

The carat weight affects how large a diamond looks, including its cut quality and shape. Choose a carat weight that works within your budget range, from 0.80 to 1.05-carat. Remember that as the total carat weight goes higher, so does its price. 

Cut

Keep in mind that cut plays a crucial role in bringing out a diamond’s true beauty. Some of the most well-known cut grades are excellent and ideal cut diamonds. A round brilliant diamond should have an excellent or ideal cut, while fancy-shaped diamonds should go for a premium grade.

You can find great selections in Blue Nile and James Allen. Blue Nile offers Ideal and Astor Ideal diamonds, while James Allen has Ideal Cut and True Hearts collections. 

Color Grade

Find the appropriate color grade whether you’re looking for colorless or fancy colored diamonds. You don’t need to pay for a D or E color grade diamond to get an actual colorless piece. G to I color grades can also appear white but at a more affordable price.

Keep in mind that various shapes reflect its color at different strengths. That is why you should also find the right balance between its shape, color, and appearance. 

Clarity

As much as possible, look for an eye-clean diamond stone with no visible inclusions or blemishes. Eye-clean diamonds range between VS1 to VS2. Avoid spending large money on an FL or IF grade diamond if you can get a lower grade diamond at an affordable price. 

Online jewelry dealers like James Allen and Blue Nile offers 3D display imagery with maximum magnification so you can inspect the diamond up-close before buying it. 

Comparing Similar Diamonds

Making comparisons will also help you filter down your preferred specs and design for your diamond ring. It includes certain considerations, such as clarity, brilliance, color, and price. Besides the 4 Cs, you should also consider other factors contributing to a diamond’s overall appearance, including polish, symmetry, and fluorescence.

Certificate

To ensure that you are buying a certified diamond, you need to check if it comes with a GIA or AGS diamond certification. Avoid diamonds certified by HRD, EGL, and IGI as their results tend to be inconsistent.

FAQS (Frequently Asked Questions)

How much is a one-carat diamond ring?

Like other high-end pieces, the price range for a one-carat diamond ring differs significantly. You can get a stunning one-carat round brilliant halo diamond engagement ring in 14k white gold at around $8,000. You can also go all out by getting a one-carat vintage diamond ring in platinum at over $9,000.

However, instead of going for the cheapest price, you need to find a premium quality diamond ring at the best value and price. Since a diamond ring is a meaningful piece that should last a lifetime, you should look for something that never goes out of style. You may also reach out to diamond experts for personalized advice. Blue Nile and James Allen offer consultations for their clients on their site. 

How big is a one-carat diamond size?

When looking at how big a diamond looks, you need to remember that carat refers to a diamond’s weight, not its size. In general, one-carat diamonds differ depending on how big they look and how big they are. One example is an oval diamond that tends to appear larger than princess-cut diamonds. It is because oval diamonds have a larger surface table.

Although some buyers give more importance to a diamond’s size and carat weight, it is recommended that you should focus on choosing a well-cut diamond instead. A stunning one-carat diamond ring can look sparkly, brilliant, and eye-catching like a higher-carat diamond ring.  

How much is the worth of a one-carat diamond?

Knowing the true value of a one-carat diamond depends on a case-to-case basis. It includes figuring out the type of cut, the number of inclusions, and how colorless it is. All these factors can affect how much a diamond is worth.

It is no doubt that diamonds make precious and stunning pieces of jewelry. However, they shouldn’t be considered as an investment. If you are planning to sell a diamond, you won’t break even at its original price. A diamond’s selling value depends on where you purchased it and where you plan to resell it.

If you like to buy and sell diamonds online, a practical option is to retain approximately 60 to 70% of its price.
