For 3 Carat Diamonds, only consider those of an ideal cut or an Excellent grade cut on the GIA scale. Choose a Clarity of VS1 or VS2, and between a G-I on the Color scale. Choose from a prominent diamond dealer that offers GIA or ASG certifications with every diamond.
A well-cut, stunning 3 Carat Diamond will capture the heart of the receiver—and all those who view it. Because of its significant carat weight, a 3 Carat Diamond offers extraordinary capacity for brilliance, sparkle and fire.
As you can see, diamonds of the same carat weight differ dramatically in their overall appeal and brilliance.
When referring to 3 Carat Diamonds, we are specifically discussing the weight. 3 Carat is equal to 600 milligrams, or 0.6 grams. From another perspective, a 3 Carat Diamond weighs approximately the same as a raisin.
Diamonds are all priced per carat. As an example, a 2.50 carat diamond may have a price of $12,280 per carat. The diamond’s price would be $12,280 x 2.50, equaling $30,700.
Diamond prices per carat also increase with higher weight categories. For example, a 2 Carat Diamond might be priced at $8,380 per carat, while a similar 3 Carat Diamond is $10,920 per carat. The price increases exponentially with weight due to the diamond’s higher weight value and higher price per carat within the weight category.
Weight ‘category’ should be noted, as prices per carat do not continually increase as weight increases. Diamond prices are often driven more by emotion than reason.
While it may seem advantageous to search for a diamond that’s just below a new weight category, such as a 2.90-2.99 Carat Diamond, that really isn’t the case.
The search for an “almost” 3 Carat Diamond has become quite popular. This popularity props up the price of those specific diamonds—making cost savings minimal. In addition, diamond cutters have become more efficient at their job, and it’s incredibly rare to find a well-cut 2.90 Carat Diamond.
Ultimately, you can search for a 2.90ct+ diamond, but we suggest not trying to find one specifically, as you’ll severely limit your search potential without really saving anything.

Through our many years of experience, we’ve vetted several diamond dealers and have a consistent pulse on the companies you can trust.
For the best diamond cuts at an exceptional value, we recommend:
Brian Gavin Diamonds: Presents super-ideal cuts with the “Brian Gavin Signature” Hearts & Arrows collection, offers only the best cut diamonds and provides high quality certification (GIA & AGS) on all diamonds. As the size of the diamond increases, the added brilliance of a Brian Gavin Black or Signature diamond really comes into play.
Bespoke Diamonds by Brian Gavin: Brian Gavin Diamonds’ distinct advantage is that he is one of the premier diamond cutters in the world. If you are looking for something rare, Brian will custom cut a diamond to your exact preferences. Pairing the diamond with one of their custom engagement rings will result in an exclusive experience.
Abe Mor Diamonds: If you live near New York City or have the opportunity to travel there, Abe Mor is a unique option. Specializing in larger diamonds, Abe Mor is an actual wholesaler who works with boutique jewelry designers in the city. He has provided unique diamond and jewelry options for many of our readers. When pursuing this route, it is best to contact us first. When working with a wholesaler its best to have a more focused idea of what you want before asking to see options.
Blue Nile: Maintains the largest online inventory of diamonds and settings, emphasizes remarkable diamond quality, offers high-quality jewelry settings, and all diamonds come with high quality certification (GIA & AGS).
When using these diamond dealers or others, follow these expert recommendations:
Diamond Size and Diamond Carat are often mistaken as meaning the same thing. Diamond Carat, however, refers to the weight of the diamond—whereas Diamond Size refers to the visual appearance.
A larger sized diamond does not mean it is of a larger carat. The table surface area, depth and other shape features are not impacted by the diamond’s carat weight. These aspects are dependent on Diamond Shape and how the diamond is cut—both of which contribute to how big a diamond appears.
As an example, a 3 Carat Oval Shaped Diamond ring like this one will likely appear larger than this 3 Carat Round Brilliant Cut in a solitaire setting. Both are stunning choices, but the size appearance differs even though the carat weight is the same.
When it comes to carat weight and size, review several options and diamond shapes to determine which diamonds are most appealing to you.
A diamond’s 4 C’s (Cut, Color, Clarity and Carat Weight) impact its beauty and brilliance in varying ways. Clarity indicates how void the diamond is of imperfections. When reviewing a diamond for Clarity, we are looking for surface defects, blemishes, inclusions and any extra facets that are present in the diamond.
The GIA Clarity scale ranges 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 the GIA grade carries validity and consistency, it’s not the only element that should be considered in regard to a diamond’s Clarity.
The differences between two grades, such as VVS2 and VS1 are rarely noticeable to the naked eye—yet the price can differ significantly. For example, 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.
That’s why we recommend reviewing the diamond yourself or having an expert assist you. We can help you avoid spending too much on a feature that will go unnoticed to the naked eye.
Properly reviewing Diamond Clarity can sometimes be challenging when looking through online inventories. For this reason, we recommend using James Allen as they are the only vendor to offer sufficiently high-quality images on all of their diamonds. With their best-in-class technology, you can find this beautiful SI2 diamond that saves you 15% over a mediocre VS2 like this one.
For 3 Carat Diamonds, our general recommendation is a minimum of a VS2 for Clarity. Most blemishes and inclusions are invisible to the naked eye at this grade. It is possible, though, to find an S1 with inclusions close to the edges. Once the diamond is placed in a setting, these inclusions may be hidden.
To maintain a reasonable spend in the area of Clarity, the highest we usually recommend is a VVS2, as there are no blemishes or inclusions visible to the naked eye.
Most importantly, an eye-clean diamond is what you should be looking for. Enlist the help of an expert if you’re not confident in this area.
Be sure to check out our Diamond Clarity guide for more information.
An exquisite 3 Carat Diamond can be found in any Diamond Shape. Based primarily on personal preference and style, Diamond Shape is often the first decision to make.
If size appearance is important to you or the receiver, it may be helpful to note the surface area difference amongst 3 Carat Diamonds of different shapes. Depending on table size (the top, flat surface of a diamond), a certain Shape may appear larger.
The chart below shares the different surface areas based on Diamond Shape:
|Diamond Shape||Approximate Table Surface Area for 3 Carat|
|Round Brilliant Cut||9.37×9.37×5.65mm|
|Pear Shaped Diamond||13.05×7.86×4.79mm|
|Heart Shaped Diamond||9.46×9.46×5.68mm|
It’s important to note that the difference between each single grade is largely unnoticeable. James Allen states 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, though, may be quite significant.
Because of the minute differences between color grades, we recommend reviewing the diamond yourself. What you see with the naked eye is more important than the GIA grading. Most online diamond dealers will offer detailed pictures and videos for this purpose.
You can also ask a diamond expert for assistance if you’re not entirely confident.
When looking at a 3 Carat Diamond’s Color, be sure the diamond appears white in relation to its setting. A beautifully colorless G graded diamond like this will maintain its white appearance in a yellow gold, white gold or platinum setting.
On the other hand, a K color diamond will likely only appear white in darker settings like this rose gold solitaire setting. Usually K color diamonds have noticeable yellow tint, but the contrast with the jewelry makes it appear clear and radiant.
Remember that a diamond’s cut is the most important element of a diamond’s beauty and value. When you have an exceptionally cut diamond, like those in the Brian Gavin Signature Hearts and Arrows Diamond collection, the harder it is to notice Color. We always recommend spending more in the area of Diamond Cut than Diamond Color.
Our general recommendation is to consider 3 Carat Diamonds in the nearly colorless range of G to I grading. These diamonds will appear colorless to the naked eye and will cost much less than those in the D to F range.
For more detail on our Color recommendations, check out our Diamond Color guide.
Our goal is for you to find the most exceptional 3 Carat Diamond—at a price that’s excellent within the market. We want you to spend in the areas that greatly affect a diamond’s beauty, and scale back in the areas that won’t be noticed by the naked eye.
Above all, we recommend reviewing the diamond yourself or having an expert assist you. We also advocate that all diamonds you are considering have either a GIA or AGS certificate. This ensures that what is stated is validated by an esteemed grading entity.
If a seller is suggesting you purchase a diamond with a different grading entity, it’s best to steer clear. No matter what the lab report states, the actual quality of the diamond is far less than what they are stating.
To ensure your 3 Carat Diamond is radiant and brilliant, and will maintain its value, follow our experts’ recommendations:
