For 4 Carat Diamonds, we recommend only considering diamonds with an ideal cut or an Excellent grade cut on the GIA scale. Choose a diamond that is G-I on the Color scale and VS1 or VS2 on the Clarity scale. Purchase your stone from a prominent diamond dealer that offers GIA or ASG certifications with every diamond.
Because of its significant carat weight, a 4 Carat Diamond has extraordinary capacity for brilliance, sparkle and fire. A stunning 4 Carat diamond that’s well-cut gives you the ‘wow’ factor and makes your loved one feel extra special.
But buying any 4 Carat Diamond will not get you the results you want. You could buy a poorly cut 4 Carat Diamond that appears dull, or one that will turn heads like this 4 Carat diamond ring in platinum.
Diamonds of the same carat weight differ dramatically in their overall appeal and brilliance. If you have questions about 4 Carat diamonds or would like help in your search, please don’t hesitate to contact us.
When we talk about 4 Carat Diamonds, we’re discussing the weight of the diamond, not its size. 4 Carat is equal to 0.8 grams or 800 milligrams.
All diamonds are priced per carat. For example, a 3.50 carat diamond might be priced at $16,550 per carat. The diamond’s price would be $16,550 x 3.50, equaling $57,925.
Diamond prices per carat also increase as the weight categories increase. For instance, a 2 Carat Diamond might be priced at $7,390 per carat, while a similar 3 Carat Diamond might be $9,970 per carat. The price per carat increases exponentially with weight because of the diamond’s higher weight value but also the higher price per carat within the weight category.
It’s important to pay attention to weight ‘category,’ as prices per carat don’t continually increase as weight increases. Diamond prices are often driven more by emotion than reason.
While it may seem advantageous to look for a diamond that’s just below a new weight category, such as a 3.90-3.99 Carat Diamond, that really isn’t the case. Diamond cutters have become more efficient at their job. In fact, it’s incredibly rare to find a well-cut 3.90 Diamond.
In addition, the search for an “almost” 4 Carat Diamond or “almost” 5 Carat Diamond has become incredibly popular. This popularity pushes up the price for those particular diamonds—making the cost savings minimal. Ultimately, you can search for a 3.90ct+ diamond, but we suggest not trying to find one specifically, as you’re severely limiting your search potential without really saving anything.

Because of their scarcity, 4 Carat Diamonds are rarely found in local shops. If you do find a 4 Carat diamond in a jewelry store, it’s likely to be cut poorly—greatly impacting the overall brilliance and beauty of the diamond.
The exception to brick and mortar stores are highly reputable vendors and diamond cutters, like Abe Mor based in New York City. Specializing in larger diamonds, Abe Mor offers exceptional quality with personalized service. They usually have a collection of 4 Carat Diamonds and can assist you in finding one that’s brilliant and well-cut. If you’re wondering if another store is offering you a high-quality diamond or a dud, contact us and we can offer you expert feedback before it’s too late.
Another highly recommended option would be to use Leibish & Co’s high-end custom design option.

For the best diamond cuts at an exceptional value, we recommend:
Offers super-ideal cuts with the “Brian Gavin Signature” Hearts & Arrows collection. Brian Gavin features only the best cut diamonds, all of which come with high quality certification (GIA & AGS).

The distinct advantage with Brian Gavin is that he’s one of the premier diamond cutters in the world. If you’re looking for something rare and have the budget, Brian will custom cut a diamond to your exact preferences. Pair the diamond with one of their custom engagement rings for an exclusive experience.
Leibish’s competitive advantage is that they have the most experience with the highest end of the diamond business. They specialize in fancy color diamonds, but they also have extensive experience with high-end large colorless diamonds as well.

When selecting a diamond from a vendor, follow these expert recommendations:
Diamond Size and Diamond Carat are often mistaken as meaning the same thing. Diamond Carat refers to the weight of the diamond—whereas Diamond Size refers to visual appearance (how large it appears).
A larger sized diamond does not mean it has a larger carat weight. The table surface area, depth, and other shape features are not impacted by carat weight. Aspects like surface area and depth depend on Diamond Shape and how the diamond is cut—both of which contribute to how big a diamond appears.
For example, a 4 Carat Pear Shaped Diamond ring will likely appear larger than a 4 Carat Round Brilliant Diamond ring like this one. Both are stunning choices. The size of the stones appear different even though the carat weight is the same.
When it comes to shape, size and carat weight, review several options to determine which diamonds appeal to you the most.
The 4 C’s (Cut, Color, Clarity and Carat Weight) of a diamond impact its beauty and brilliance. Clarity, for instance, indicates how void the diamond is of blemishes, surface defects and inclusions.
The GIA grades Clarity on the following scale from best to worst: Internally Flawless (IF), Very Very Small Inclusions 1 (VVS1), Very Very Small Inclusions 2 (VVS2), Very Small Inclusions 1 (VS1), Very Small Inclusions 2 (VS2), Small Inclusions 1 (SI1), Small Inclusions 2 (SI2), Inclusions 1 (I1), Inclusions 2 (I2).
While it’s important to review the Clarity grading from the GIA or AGS, you should also look closely at the diamond yourself to determine if any imperfections are visible to the naked eye. You can also have an expert assist you, helping you to avoid spending too much on a characteristic that will go unnoticed.
The differences between two grades, such as VVS1 and IF, are rarely noticed by the naked eye although the price can differ significantly. An eye-clean diamond that’s graded lower than a flawless diamond will look identical—assuming all else is equal. The difference you’ll notice is just in the price.
Due to their significant carat weight, we suggest a minimum of a VS2 Clarity for 4 Carat Diamonds. Most inclusions and blemishes are invisible to the naked eye at this grade. You may be able to find an S1, though, with inclusions close to the edge, meaning that once the diamond is in its setting, these inclusions may be hidden.
Here is a beautiful H VS1 Asscher:
To maintain a reasonable spend on Clarity, the highest we usually recommend is a VVS2 diamond, as no blemishes or inclusions will be visible to the naked eye.
Overall, an eye-clean diamond is what you should be looking for. Ask for the help of an expert if you’re not confident in this area.
Stunning 4 Carat Diamonds can be found in almost any Diamond Shape. Your Diamond Shape should be based primarily on personal preference and style.
If a larger size appearance is important to you and the wearer, it may be helpful to consider the surface area differences among shapes. Depending on the table size (the top, flat surface of a diamond), a diamond of a certain shape may appear larger than another.
The chart below lists the surface areas for each Diamond Shape:
|Diamond Shape||Approximate Table Surface Area for 4 Carat|
|Round Brilliant Cut||10.32×10.32×6.22mm|
|Pear Shaped Diamond||14.36×8.65×5.28mm|
|Heart Shaped Diamond||10.42×10.42×6.25mm|
Diamond Color, one of the 4 Cs, is graded by the GIA on a scale from D to Z. D indicates the most clear, colorless diamonds and Z signifies diamonds that carry a noticeable yellow or brown tint.
The difference between each single grade is primarily unnoticeable. James Allen explains in their Diamond Color article: “Most people find it very difficult (if not impossible) to tell the difference from one color grade to another.” The difference in price can be significant, though.
Because of the minimal differences between color grades, we recommend reviewing the diamond yourself to ensure the diamond appears colorless. What you see with the naked eye is more important than the Color grade the diamond is given. You can often review diamonds up-close even online with advanced photography. You can also ask a diamond expert to help you evaluate a diamond’s Color.
Be sure the diamond also appears white in relation to its setting. A colorless G graded diamond like this will appear white in any setting: yellow gold, white gold, rose gold or platinum.
On the other hand, a K diamond will likely only appear white with a darker setting like this yellow gold solitaire setting. While K color diamonds have a noticeable tint, the contrast with the jewelry makes it appear clear and radiant.
For 4 Carat Diamonds, we recommend stones in the nearly colorless range of G to I. These diamonds appear colorless to the naked eye and will cost much less than those in the D to F range.
Remember that Diamond Cut is the most important element of a diamond’s beauty. When you have an exceptionally well-cut diamond, like those in the Brian Gavin Signature Hearts and Arrows Diamond collection, the harder it is to notice Color. We recommend spending more in the area of Diamond Cut than Diamond Color, no matter the carat weight.
Our goal is to help you find the most exceptional 4 Carat Diamond at an excellent price. We want you to spend your budget where it will matter—and scale back in the areas that will go unnoticed.
Most importantly, we recommend reviewing every 4 Carat Diamond yourself or having an expert assist you.
You should also ensure that your diamond comes with a certificate from a reputable source like the GIA or AGS. If a seller is suggesting you purchase a diamond from a different grading entity, it’s best to steer clear, especially with 4 Carat Diamonds. No matter what their lab report claims, the actual quality of the diamond is far less than what the certificate states.
To ensure your 4 Carat Diamond is truly stunning, follow our experts’ recommendations:
