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

Choosing the perfect diamond involves narrowing down your options and picking high-quality pieces without going over your budget. You also need to compare each diamond to check which one will give you the most brilliance and flare. Follow this step-by-step guide to find the best real diamond ring without overpaying. 

Diamond Shape

Choosing the diamond shape is the starting point of the buying process. No shape is superior to the other – it’s up to you or your partner’s personal preference. Round brilliants are the most famous diamond shape for engagement rings as they give off the most sparkle. Others prefer unique shapes, such as princess, baguette, cushion, or oval. 

If you are still unsure of what your partner likes, you can consult her family and friends. What’s crucial is to select a specific shape to narrow down your search and compare other diamond designs. 

Carat Weight

Is your partner expecting a low or high carat diamond? Are you looking for a stone that is decent enough to get noticed without being flashy? Carat weight greatly affects how large a diamond looks, including its shape and cut quality. Choose a carat weight range that works for your budget, such as 0.80 to a 1.05-carat diamond. Keep in mind that as the carat weight goes higher, so does its price.

Cut Quality

The cut quality plays an essential role in a diamond’s overall beauty. There is no standard cut grade across all diamond vendors. In general, the most preferred cut grade is the Excellent and Ideal cut diamonds. 

When searching for round diamonds at Blue Nile’s website, limit your search to Ideal and Astor Ideal diamonds. Meanwhile, stick to Ideal Cut and True Hearts when buying at James Allen. 

For those who prefer a round brilliant diamond ring, look for Ideal or Excellent grade diamonds. A Premium grade is the recommended quality for the fancy shape diamond. 

Color Grade Range

Your ultimate goal when finding the right color grade is to find a diamond that appears colorless. However, you don’t need to pay for D or E grade diamonds to get a completely colorless piece. Diamonds with a G to I grades may appear white but tend to be less expensive.

Different shapes reflect the color at various strengths, so your choice of optimal color while balancing its appearance with its price will entirely depend on your chosen diamond shape.

Clarity Grade

To get the best clarity grade for your diamond ring, look for an eye-clean diamond stone, which means it doesn’t have inclusions or blemishes seen by the naked eye. Depending on its shape, you can often find eye-clean diamonds within the VS1 to VS2 range. You don’t want to spend large money on an FL or IF grade diamond when you can get a lower graded diamond at a much affordable price.

Blue Nile and James Nile use high-tech display imagery so you can view the diamond up-close to inspect its clarity. Look at it closely and check if you see any blemishes or inclusions.

Comparing Similar Diamonds

Once you have filtered down your preferred styles and specs for your diamond ring, it’s time to compare similar stones to determine which one you should buy. In this part, you have to consider certain aspects, including price, brilliance, and clarity.

Besides the 4 Cs, you may also consider other characteristics contributing to the diamond’s appearance and value, such as symmetry, polish, and fluorescence.


Ensure that the diamond stone is GIA or AGS-certified, especially if you’re searching for a loose diamond. Steer away from HRD, EGL, and IGI certified diamonds since their results are not often reliable due to inconsistent grading. 

Expert Opinion

Before making your final decision to buy a diamond ring, ask a professional diamond consultant to review your final choice. They will give your diamond a close look to see if you made the right purchase according to your preference and budget. Having an expert’s opinion gives you more confidence by ensuring that you get what you pay for.


With thousands of ring designs, metals, color, and center stone combinations to choose from, picking the best diamond ring can be a touch process. It also involves making a personal decision, where you have to factor in your lifestyle and tastes. 

This guide has put together a detailed product review of the best real diamond rings from top online diamond retailers: James Allen and Blue Nile. Both companies offer countless diamond rings that come in hundreds of designs and settings to suit everyone’s tastes and budget.

In truth, there is no such thing as the best style of diamond ring for everyone. For those searching for the perfect real diamond ring, it would be best to choose a setting that perfectly matches your style, then customize it with your chosen brilliant diamond.

FAQs (Frequently Asked Questions)

How do I know if the price I’m paying for the diamond is fair?

To determine if you are getting your money’s worth, you need to familiarize yourself with how diamonds are graded based on the 4 C standard and how each quality directly impacts its prices. The next step is to visit online diamond retailers like James Allen and Blue Nile and browse through their diamond ring inventory. You can do price checks by comparing different diamond rings that match your preference.

One mistake that people make is making unbalanced assessments by comparing two diamonds with different cut properties. Blue Nile and James Allen offer a smooth shopping experience by allowing you to compare various diamond rings with their user-friendly interface. 

Like any product, you need to get what you pay for. Even if you saw an advertisement that flashes a 90% sale, bargains such as this one never existed, but fair deals do. Turning to reputable online diamond vendors is a practical way to get the perfect diamond ring at the best value and price.

Which are the most popular cutting styles and shapes?

Rough diamonds are often polished into ten different shapes. Some shapes have become more popular over the years due to changes in fashion trends and consumer tastes. However, full-cut round brilliant diamonds are consistently the top seller among the shapes. When cut to ideal proportions, a brilliant round diamond offers the best light performance and sparkle than other types of shapes.

Coming in at second place is the cushion cut. In the US jewelry market, cushion cut diamonds have overtaken princess cuts due to a recent surge in demand. Meanwhile, triangle cut shapes are one of the rare types and seldom seen in jewelry retailer shops. However, they might still appeal to those looking for exquisite choices.  

You may also consider the radiant and Asscher cut as it combines the qualities of a round and cushion cut diamond.

Is a diamond certificate or grading report necessary when buying a diamond?

Whenever you shop for diamonds, one of the first things you should ask the vendor is whether the diamond comes with a certificate. A diamond certificate from highly regarded institutions is the most useful, especially if you plan to sell the diamond in the future.

Ideally, the grading certificate should be issued by well-known and respected institutions like the American Gem Society (AGS) and the Gemological Institute of America (GIA). Stay away from diamonds with grading certificates from IGI and EGL. The accuracy of their diamond qualities can be unreliable and inconsistent.

Some jewelers have their in-house appraisals or documents from a third-party neutral grading company. If you come across jewelers such as these, you should be alert. These are unethical marketing tactics used by jewelers to manipulate the value of your purchase.
