How Much Does a Four Carat Diamond Cost?

While the 4Cs contribute to the beauty and affordability of diamonds, each of these characteristics impacts the overall price of the diamond. The higher the quality of the cut, the more expensive the diamond will be, while the lower the quality of the color, the less expensive the diamond will be. However, various other factors can influence the price. Fluorescence and the amount of material in a diamond are also essential factors in determining its price, so consider these factors before purchasing a diamond.

Please continue reading if you want to know how much a four-carat diamond is worth. These gemstones are extremely rare and difficult to come by in the local marketplace. As a result, they are unlikely to be found in a traditional jeweler’s store, where they can cost millions of dollars each. Because of high-quality diamond cutters and advanced technological advances, these gems can now be purchased online or in a jeweler’s showroom for a fraction of the price you’d pay in a traditional brick-and-mortar store.

The Gemological Institute of America (GIA) and the American Gem Society (AGS) are two of the world’s most reputable diamond grading laboratories. These certifications are non-profit and provide greater transparency than other types of certification. Some of these laboratories are more stringent than others, and others are hedged for the company’s benefit. Decide on a diamond with GIA or AGSL certification to avoid being disappointed by a low-quality diamond.

How Much Does a Four Carat Diamond Cost?

According to the cut quality, clarity, clarity, and color of the diamond, the cost of a 4-carat diamond ring can range from $30,000 to $250,000 or more on average, depending on the design. As a general rule, the higher the quality of a diamond of this carat weight, the more expensive the diamond is.

As we discussed in our guide to the 4Cs, the carat weight of a diamond is only one of four factors that influence the price of a diamond. The other characteristics are the cut quality, clarity, and product color.

Each of these factors has a significant impact on the price of a diamond, mainly when the stone is large, such as a four-carat diamond. This is because color, clarity, and cut quality can be more noticeable in a four-carat diamond than in a smaller stone of the same weight.

In this case, a 4.01-carat round diamond from James Allen with J color and VS1 clarity will set you back $47,230. For comparison, this E-color diamond from James Allen is priced at $104,790. It is identical in cut quality with very similar carat weight and only one clarity grade lower than the diamond in question.

Depending on its size and clarity, a four-carat diamond with the highest color and clarity grades can be worth as much as $250,000 or more. Examples include this 4.07 carat round brilliant cut diamond from Blue Nile that is D color and IF clarity, which sells for $250,278 — more than five times the price of the J color, VS1 diamond mentioned above.

In short, the exact price you’ll pay for a 4-carat diamond is determined by the three other Cs — the quality of the cut, the clarity, and the color of the diamond. When it comes to getting the best value, we recommend staying within the parameters we outlined above: color in the G-I range and a clarity grade in the VS1 or VS2 range, respectively.

Finally, a fifth factor can impact the price of a 4-carat diamond: the shape of the diamond. Similar to what we discussed in our guide to diamond shapes and pricing, the price of a diamond can vary depending on its shape, with some shapes costing more per carat than others.

Let us consider the 4.02 carat, E color, VS2 clarity round brilliant cut diamond from above, which costs $104,790, or $26,067 per carat, and $104,790. A pear-shaped diamond with the same clarity, clarity cut quality, and carat weight (but one color grade higher) costs $82,300, or $20,473 per carat compared to a round diamond with the same characteristics. In most cases, the same is true for other unusual shapes.

When it comes to diamond rings, a 4.5-carat diamond ring can cost anywhere from $40,000 to as much as $450,000 for diamonds close to the 5-carat range. Factors such as cut quality, clarity, clarity, shape, and color influence the value and selling price of a diamond, just as they do with a four-carat diamond.

Overview of Pricing for 4 Carat Diamonds

The technical factors that determine the value of your 4ct diamond will be discussed here. It’s also crucial to consider where you’ll buy your diamond. We’ve written an article about the best places to buy a diamond engagement ring. When we talk about 4-carat diamonds, we’re talking about their weight, not their size. 0.8 grammas, or 800 milligrams, equals 4 carats.

The cost of a diamond is determined by its carat weight. A 4.50-carat diamond, for example, could cost $23,500 per carat, and the price of the diamond would be $23,500 multiplied by 4.50 for a total of $105,750.

The price of a diamond per carat rises as the weight category rises. For example, a 3 carat diamond like James Allen might cost $12,691 per carat, whereas a 4-carat diamond might cost $16,708.

Because of the diamond’s higher weight value and the higher price per carat within the weight category, the price per carat increases exponentially with weight.

It’s crucial to pay attention to the weight ‘category’ because prices per carat don’t always rise as weight rises. Diamond prices are frequently influenced by emotion rather than logic.

While it may appear that looking for a diamond just below a new weight category, such as a 3.90-3.99 Carat Diamond, is advantageous, this is not the case. Diamond cutters have improved their productivity, and finding a well-cut 3.90 Diamond is extremely rare.

Furthermore, looking for an “almost” 4 carat or “almost” 5-carat diamond has become extremely popular. The price of those particular diamonds rises due to their popularity, so the cost savings are minimal. Finally, you can look for a 3.90ct+ diamond, but we advise against doing so because you’ll be severely limiting your search potential without saving anything. If you’re looking for a 4-carat diamond, read this guide to find out how to choose a great diamond rather than a dud. Understanding a few fundamentals will pay off handsomely in terms of your stone’s overall beauty and value.

Diamonds Have Four Characteristics (Or Cs).


Diamond cut is the most important of the four Cs because it has the most significant impact on a diamond’s overall beauty. When determining the quality of the cut, the diamond grader considers the skill with which the cutter fashioned the diamond. The more precisely a diamond is cut, the more enthralling the diamond appears to be to the human gaze. Check out the complete tutorial on the patented Light Performance cut grade developed by the American Gem Society, or read on to learn more about diamond cut grading.


The GIA grades diamond color on a scale of D to Z. D diamonds are the most colorless, while Z diamonds have a noticeable yellow or brown tint.

The distinction between grades is minimal. “Most people find it difficult (if not impossible) to tell the difference between color grades,” says James Allen in their Diamond Color article. But the price difference can be significant.

We recommend inspecting the diamond yourself because color grades are close to ensuring it is colorless. What you see is more important than the diamond’s color grade. Online, advanced photography allows you to see diamonds up close. To determine a diamond’s color, you can consult an expert.

A diamond should appear white relative to its setting. A colorless G diamond will appear white in yellow, white, rose, or platinum.

A K diamond will appear white only in a darker setting – yellow gold or raised gold. Contrast with the jewelers makes the K color diamond appear clear and radiant.

We recommend G-I colorless diamonds for 4-carat diamonds. These diamonds are colorless to the naked eye and cost less than D-F diamonds.

Remember that a diamond’s cut is its most important feature. It is harder to notice color in a well-cut diamond, like those in the Brian Gavin Signature Hearts and Arrows Diamond collection. We recommend investing in diamond cut over diamond color regardless of carat weight.


You can find almost any Diamond Shape in a 4-carat diamond. Your Diamond Shape should primarily reflect your taste and style.

If the appearance of a larger size is important to you and the wearer, it’s worth considering the surface area differences between shapes. A diamond of one shape may appear larger than another depending on the table size (the top, flat surface of a diamond).


Each of a diamond’s 4 Cs impacts its beauty and brilliance. Clarity, for example, measures the absence of blemishes, surface defects, and inclusions.

The GIA ranks clarity from best to worst: Very Small Inclusions 1 (VVS1), Very Small Inclusions 2 (VVS2), Small Inclusions 1 (SI1), Small Inclusions 2 (SI2), Inclusions 1 (I1), and Inclusions 2 (I2) (I2)

While the GIA or AGS Clarity grading is essential, you should also examine the diamond closely to see if any flaws are visible. You can also hire a professional to help you avoid overpaying for a minor feature.

The price difference between two grades, such as VVS1 and IF, is often not noticeable. If all other factors are equal, an eye-clean diamond and a flawless diamond will appear identical, and the price is the only difference.

Due to their considerable carat weight, we recommend VS2 clarity for 4-carat diamonds. At this grade, most inclusions and blemishes are invisible. You can find an S1 with inclusions close to the edge, which will hide once the diamond is set.

We usually recommend a VVS2 diamond to keep costs down, which has no visible blemishes or inclusions. Overall, you want an eye-clean diamond. If you’re unsure, seek expert advice.

“The most effective method of cleaning diamond rings is to prepare a solution of warm (almost hot) water and dishwashing soap.

The most significant influence on a diamond’s price is the jeweler’s markup. Retailers and prestigious brands will mark up prices. Aside from that, customers pay for store overhead.
