Your Expert Guide to 5 Carat Diamond Rings

A 5-carat diamond ring isn’t simply a purchase or a piece of jewelry; it’s an elegant statement, a timeless investment. 

With less than 1% of diamonds reaching the coveted 5-carat category, diamonds with this rating are rare and desirable, and as such, careful consideration is required before making a purchase.

In this PriceScope educational article, we outline the key factors to keep in mind when searching for your perfect 5-carat diamond ring. 

Whether you’re investing in a breathtaking engagement ring, an enduring family heirloom, or a beautiful addition to your own jewelry box, we’ll outline everything you need to know about 5-carat diamond rings so you can be assured you’re making the right investment.  

What Does a 5-Carat Diamond Ring Cost?

Contrary to popular belief, the cost of a 5-carat diamond ring isn’t solely dictated by its size (although the size of the stone will definitely turn heads). Other key properties such as cut quality, colour, clarity, and shape all significantly impact the price. 

Larger diamonds of superior quality are rare and difficult to come by, hence as the carat weight increases, so does the cost per carat. With this in mind, the cost of a high-quality, 5-carat natural diamond can range from $50,000 to more than $200,000.

Staying up-to-date with the current market prices is crucial when searching for your next diamond investment. PriceScope’s latest diamond prices chart provides real-time data on 5-carat diamonds, helping you stay informed, make a wise investment decision, and get the best value for your money.

The 4Cs in 5-Carat Diamonds 

All diamonds are priced and graded according to the 4Cs: cut quality, color, clarity, and carat weight. 

Gemological laboratories such as the Gemological Institute of America (GIA) have long set the standard for diamond cut grading. While traditional cut grades range from “Excellent” to “Poor”, the term “Ideal” may be familiar to some having been the highest cut quality rating in the now-retired AGS cut scale.

Today, GIA offers diamonds that not only receive an “Excellent” cut grade, but are also optionally paired with an AGS Ideal light performance report, giving buyers a greater level of assurance. 

These dual-certified diamonds – available from trusted vendors like Whiteflash – combine the precision of GIA grading with the performance insights that were once exclusive to AGS. 

Why Is Cut Quality for 5-Carat Diamonds So Important?

Given the stone’s size at this carat weight, cut quality is the most important factor when shopping for your 5-carat diamond. The cut quality of a diamond is the key element that determines the diamond’s sparkle and brilliance. 

Beyond the basic cut grade, some vendors go a step further by providing in-depth diamond analytics and light performance images, such as ASET, Ideal Scope, and Hearts & Arrows views. 

The Gem Certification & Assurance Lab’s 8X® report includes this advanced level of analysis as standard, offering light performance maps and optical symmetry data. For those seeking transparency and assurance in cut quality, diamonds with GCAL 8X® or vendor-supplied imaging – like the Diamond Image Package offered as standard by Whiteflash – are a valuable resource.

Choosing a 5-Carat Diamond That Sparkles

Generally speaking, a higher cut quality, such as an “Excellent” cut diamond, will provide greater sparkle, while a “Poor” cut can make the diamond look dull, regardless of its color and clarity. 

Whilst cut quality is the most important factor to consider in a 5-carat diamond, the shape of the stone can likewise affect its visual impact. When shopping for a round 5-carat diamond, we advise looking for an “Excellent” cut to truly draw the eye to the brilliance of your stone, whilst in fancy-shaped diamonds, a cut rated “Very Good” or better will be equally admired. 

5-Carat Diamond Color

The color rating of a diamond is given based on the presence of any discernible hue in the stone. The diamond color grades, as outlined by the GIA, range from D (colorless) to Z (light yellow). 

According to this scale, diamond color categories are: 

Diamond Color Chart: The Official GIA Color Scale

Colorless: D, E, F 

Near-Colorless: G, H, I, J 

Faint: K, L, M 

Very Light: N, O, P, Q, R 

Light: S, T, U, V, W, X, Y, Z 

Color distinctions between grades can often be very subtle, most often unnoticed by the untrained eye. 

For a larger diamond, like a 5-carat, a higher color grade within the colorless range is usually most desirable, as larger stones can often make color tints more visible. 

However, the visual appearance of a 5-carat diamond’s color can often be dependent on the diamond’s shape. For example, H and I color-rated diamonds can still appear white/clear in well-cut round diamonds, whilst shapes like cushion or radiant may show more warmth. 

5-Carat Diamond Clarity 

A diamond’s clarity refers to the number of inclusions and blemishes in the stone. The Gemological Institute of America clarity scale contains 11 grades, established and applied to diamonds when assessed under 10x magnification: 

  • Flawless (FL)
  • Internally Flawless (IF)
  • Very, Very Slightly Included (VVS1 and VVS2)
  • Very Slightly Included (VS1 and VS2)
  • Slightly Included (Sl1 and Sl2)
  • Included (I1, I2, and I3) 

GIA Diamond Clarity Scale

In a 5-carat diamond, it’s advisable to opt for eye-clean clarity (VS2 or better). However, in some shapes, such as emerald or Asscher, a higher clarity grade may be required due to the shape’s open tables. 

How Big is a 5-Carat Diamond? 

When it comes to shopping for diamonds, it’s important to remember that the carat weight is not equal to a specific size. For example, diamonds with poor proportions (i.e. too deep or too shallow) can look smaller or lack brilliance, despite being in the same carat weight category. 

That being said, the carat weight and size of a diamond are often interconnected. A 5-carat diamond typically measures around 11mm in diameter. However, the perceived size can vary depending on its cut. 

Shapes like the oval or marquise diamond can appear larger, whilst still weighing 5 carats, due to their elongated structure. 

5-Carat Diamond Engagement Ring Inspiration 

If your hope is to elicit a gasp from your beloved when you pop the question, a 5-carat diamond ring will definitely help you to achieve just that. 

One of the many benefits of investing in a stone of this size is the opportunity it unlocks for customised ring settings. You might choose to enhance the beauty of your diamond by opting for a setting that incorporates complementary side stones (like the basket setting), or surrounds your central stone with smaller diamonds, colored diamonds, or gemstones (like the halo setting). 

Most people start by shopping for their perfect 5-carat diamond. Once you’ve settled on your ideal stone, you’ll have a better idea of your remaining budget and the setting options that are open to you.

Finding the Perfect 5-Carat Diamond Ring: Choosing the Right Shape 

Diamonds are available in a number of different shapes, each of which provides a different look and aesthetic for your ring.

When selecting the shape of your 5-carat diamond, there are a few important considerations to keep in mind. Whilst round cut diamonds, known for their brilliance, are the most popular, other shapes (known as “fancy cuts”) are equally stunning.

It’s important to remember that the ideal diamond shape is usually a matter of personal preference, so when choosing your stone, be sure to think about how it suits your personal style, or the style of the wearer.

The shape of your diamond won’t only impact the final look of your ring, but it can also impact cost, too, which is something to keep in mind if you’re shopping with a budget in place.

Round Cut 5-Carat Diamond Rings 

The round cut diamond is the most popular and traditional diamond shape, accounting for approximately 75% of all diamonds sold. This cut is also, generally, the most expensive given that more waste is created in the cutting process compared with other shapes.

Round cut diamonds provide a classic and timeless aesthetic, with the shape emphasizing the stone’s brilliance and sparkle.

The princess cut’s distinctive square shape with pointed corners provides a classic yet contemporary feel, best emphasized when set with box claws to show off the diamond’s shape and sparkle.

Making Sure You Purchase A Certified 5-Carat Diamond

Whatever the motivation for your purchase, a 5-carat diamond is a sizable investment, so it’s important to ensure you choose a reputable seller who can provide complete certifications for your new stone. 

This is especially true of lab-grown diamonds — GIA or IGI certification is essential, particularly at this carat weight and price point, to ensure grading accuracy and resale value. 

Purchasing from a trusted supplier who can provide genuine certifications for your 5-carat diamond has a number of benefits, including: 

1. Authenticity 

Diamond certification from a reputable lab, like GIA or IGI, guarantees that the diamond is real and not a synthetic or lookalike stone, such as cubic zirconia or moissanite. 

2. Verified Quality 

A certified diamond is issued with a report detailing its specification in relation to the 4Cs. This document outlines the diamond’s qualities in terms of carat weight, cut quality, color, and clarity, providing transparency about its characteristics so you have full understanding of your purchase. 

3. Value for Money 

Diamond certification helps to provide peace of mind that you’re paying a fair price for your diamond. With all the information regarding the stone’s quality and characteristics, you’ll be able to compare prices across different sellers and make a more informed purchasing decision. 

4. Resale Value 

Having a certification with your stone will be crucial if you ever decide to sell or trade it. A diamond certification will bring higher resale value as the next buyer or jeweler can be confident about its quality. 

5. Insurance 

Insurers will often require specific details relating to your diamond if it is to be insured under your home or personal possessions policy. A diamond certification will help to establish and verify the diamond’s value so that, in the event of a claim, it can be replaced accurately.
