High quality 2 Carat Diamond Engagement Rings dazzle, shine and show off their brilliance. When purchasing such a large diamond, even the smallest issues can lead to big problems. Here’s a stunning 2 carat diamond, while this seemingly similar diamond is worlds apart in quality.

If you’re looking for a 2 Carat Diamond Ring, several key components must be examined. Well cut diamonds of this carat are hard to come by, and require extra attention during the search process. Selection of a diamond, ring and seller should be considerably detailed. To get the best value for your money, you’ll need to know how to evaluate the 4cs of diamonds. These basics will help you choose a diamond that is exceptionally brilliant and full of life.

What is a 2 Carat Diamond?

A 2 Carat (or Two Carat) Diamond simply refers to the weight of the diamond. 2 carat equals 400 milligrams, or 0.4 grams. To put it in perspective, a 2 Carat Diamond weighs roughly the same as half of a raisin.

It’s important to note that because of their scarcity, 2 Carat Diamonds are rarely found in local stores–and if they are, they are likely to be of a poor quality cut.

Several online diamond dealers offer a range of exquisite 2 Carat Diamond engagement rings. Significant differences in beauty exist among these diamonds, along with significant differences in price. And a higher price doesn’t always mean a better diamond.

In terms of pricing, diamonds are all priced per carat. For example, a 0.50 carat diamond may have a price of $1,400 per carat. The diamond’s price for the stone would be $1,400 x 0.50, equaling $700.

In addition, diamond prices per carat increase as you reach higher weight categories. Diamond prices increase exponentially with weight because of the diamond’s higher weight value and the higher price per carat for the increased weight category.  For example, a 2 Carat Diamond like this one might be $8,380 per carat, while a similar 3 Carat Diamond such as this one might be priced at $10,920 per carat.

We stress categories, as prices per carat do not continually increase as weight is increased. Diamonds are retail products driven by emotion more than reason.

It may seem advantageous to look for a diamond that’s just below a new weight category, such as a 1.90-1.99 Carat Diamond. That really isn’t the case, though. Diamond cutters have become more efficient at their job, and the search for an “almost” 2 Carat Diamond has become increasingly popular.  This influx props up the price for those particular diamonds—making the cost savings minimal.

While ultimately you can search for a 1.90ct+ diamond, we suggest not trying to find one specifically. You’ll severely limit your search potential without really saving anything.

Remember that diamond pricing is often subjective, because it’s all about the feelings. These “feelings” within the diamond industry are the sole reason there are many poor cut diamonds on the market.

We’re here to help you avoid purchasing one of those diamonds.

Where To Buy a 2 Carat Diamond Ring

With a 2 Carat Diamond Ring, you have increased flexibility and options because of a larger budget and carat weight. While Blue Nile and James Allen still have amazing advantages built into their business model, other factors come into play with the increased budget.

By looking online, you have a great chance of finding an extraordinary 2 Carat Diamond at an excellent price point.

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.

When using these diamond dealers or any others, be sure to keep the following in mind:

  • Select a 2 Carat Diamond with an ideal cut or GIA grade of Excellent. Cut is the aspect that most greatly impacts beauty, brilliance and fire. You can reduce the grading in the other 4cs of diamonds such as Color or Clarity, but don’t sacrifice in the area of Diamond Cut.
  • Compare price, brilliance and cut quality to other similar diamond engagement rings before completing a purchase.
  • Only consider 2 Carat Diamonds that carry a GIA or AGS certificate. These two grading entities are the most trusted and reliable in the industry.

Ask a diamond expert for help in evaluating the 4cs of diamonds. A professional opinion can save you from making a poor purchase. And we can assist you in finding the most beautiful, radiant diamond.

The Difference Between Diamond Carat and Diamond Size

Many people confuse the terms “Diamond Carat” and “Diamond Size.” But there’s a big difference.

Diamond Carat specifically refers to the weight of the diamond. Carat weight doesn’t impact table surface area, depth or any other shape feature. A larger carat does not mean a larger size.

Size, on the other hand, has to do with the visual appearance of the diamond. For example, an Oval Shaped Diamond will likely appear larger than a Round Brilliant Cut in the same carat only because of its elongated shape.

Various components, such as surface area and depth play into the diamond’s size. Two diamonds of the same carat usually appear different in size depending on their shape design and cut quality.

2 Carat Diamond Engagement Rings: Cuts, Shapes, and Sizes

An exquisite 2 Carat Diamond with a gorgeous setting will be remarkable in any Diamond Shape. As such, Diamond Shape should be selected based on personal preference and style of the wearer.

How 2 Carat Diamonds Are Sized

Diamonds are cut by carat weight, not by size. However, there is a surface area difference among diamond shapes — which can impact how big a diamond looks. Depending on the table size (the top leveled surface of a diamond), 2 Carat Diamonds can appear larger in certain shapes.

Our chart below gives you the surface area sizes for 2 Carat Diamond Shapes. The sizes are measured in millimeters, not inches.

Diamond ShapeApproximate Table Surface for 2 Carat
Round Brilliant Cut8.19×8.19mm
Princess Cut6.94×6.94mm
Emerald Cut8.42×6.24mm
Asscher Cut7.07×7.07mm
Radiant Cut7.28×7.28mm
Cushion Cut7.34×7.34mm
Oval Diamond10.23×6.82mm
Pear Shaped Diamond11.4×6.87mm
Heart Shaped Diamond8.27×8.27mm
Marquise Diamond13.08×6.54mm
Trillion Diamond9.75×9.75mm

How Engagement Rings are Sized

When buying engagement rings, it’s important to know the right ring size for the wearer. For a surprise proposal, match the size of an existing ring or have a friend try to get that information for you. For the most accurate measurement, we suggest ordering a complimentary plastic ring sizer from James Allen or Blue Nile.  

Rings are sized based on how many millimeters (mm) the diameter is. The most popular sizes for women are 5, 6 and 7. A size 5 is equal to a 14.3mm diameter. Size 6 equals 14.7mm and size 7 equals 14.9mm. Find the ideal size to help prevent resizing and needing to send back the ring after the proposal.

2 Carat Diamond Engagement Rings: Clarity

Consider the 4cs of diamonds (Cut, Color, Clarity and Carat Weight) to ensure you spend your budget on elements that matter – and avoid spending in areas that won’t provide additional benefit or beauty.

Evaluating for Clarity is essential in all diamonds, but especially 2 Carat Diamonds. When compared with 1 Carat Diamonds of the same shape, 2 Carat Diamonds will generally have a larger table (the top, flat leveled surface of a diamond). The Clarity of the diamond will dictate how many inclusions, surface defects (or blemishes) and extra facets are present.

We suggest reviewing the Clarity of a diamond yourself or asking for the assistance of an expert. What you see with the naked eye is more important than what a diamond’s lab report says.

For example, a low clarity eye-clean diamond will look identical to a flawless diamond assuming all else is equal (yet will cost far, far less). Eye-clean 2 Carat diamonds can be found but not as easily as eye-clean diamonds of a lesser Carat weight.

James Allen is the only vendor offering sufficiently high quality images on all of their diamonds for reviewing Clarity. With their technology, you can determine by sight which diamonds are more attractive and clear. Even if a diamond’s official Clarity grade is lower, it may offer more beauty and clarity to the naked eye than another diamond of a higher grade.

The GIA scale of diamond clarity 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).

For 2 Carat Diamond engagement rings, we generally recommend a minimum of a VS1 grade, as inclusions and blemishes will be invisible to the naked eye. You may be able to find a VS2 with inclusions near the edges of the diamond–that, depending on shape, may be covered by the setting prongs.

The maximum Clarity rating, within a reasonable budget, will usually be a VVS2, which provides no inclusions or blemishes to the naked eye.

Remember though that an eye-clean diamond is most important when it comes to Clarity, so be sure to review it yourself or have an expert assist you.

2 Carat Diamond Engagement Rings: Color

Another one of the 4cs of diamonds is Color. Selecting the Color of your 2 Carat Diamond requires a bit of extra attention.

While it’s nearly impossible for the naked eye to tell the difference between color grades, the price difference is significant.

Color is graded on a scale from D to Z by the GIA. The D grade represents the most clear or colorless a diamond can be. Z represents a diamond that contains easily noticed yellow or brown tint.

Because it’s incredibly difficult for the naked eye to notice the differences between Color grades, we recommend reviewing diamond engagement rings closely or having an expert assist you.

While the grading on the GIA certificate is important, it’s more important to determine how the Color appears to you and your loved one.

In addition, you’ll want to make sure the diamond appears white in relation to its setting. Engagement rings are available in 18k or 14k white gold, rose gold, yellow gold, and platinum settings. A K color diamond may look vibrant in a yellow gold setting, but may appear tinted in a white gold setting. If you’re choosing a diamond in a slightly lower Color grade, just ensure it’s contrasted by a setting that’s darker.

For 2 Carat Diamond engagement rings, we generally recommend selecting within the nearly colorless range of G to I. Diamonds in this range will look just as colorless as those in the D to F range but will cost much less.

Cut impacts a diamond’s beauty and brilliance more significantly than Diamond Color. When you have a Cut grade of Excellent or ideal, Color is harder to discern.

How To Get The Best Value For a 2 Carat Diamond Ring

If you’re in the market to purchase a diamond of considerable carat weight, quality should be more important than anything else–even if you need to slightly reduce your carat weight to stay within your ring budget. The increased brilliance, fire and overall radiance of a high quality diamond in a lesser Carat will outweigh and outshine any money spent on a poorly cut 2 Carat Diamond.

To ensure your diamond is exactly what the diamond dealer is stating, ensure the diamond comes with either a GIA or AGS certificate. The GIA and AGS are the two renowned and well-respected diamond grading entities that issue accurate and consistent reports for diamonds. Although certification isn’t one of the 4cs of diamonds, it is extremely important.

If a diamond seller is trying to convince you to purchase a diamond with any other lab grading entity, politely decline their invitation. The actual quality of those diamonds are much less than what they’re portraying to be “true.”

To select exquisite 2 Carat Diamond engagement rings at an exceptional value, follow our expert recommendations:

  • Diamond Shape: Diamond Shape is selected primarily on personal preference and style. Match your Shape with a setting that is complementary and offers stability. For example, ensure the corners of a Princess Cut Diamond are protected with prongs.
  • Diamond Cut: Diamond Cut is the most important of the 4cs of diamonds. It dictates how much brilliance and sparkle a diamond has. Choose only an Excellent or ideal cut for 2 Carat Diamond engagement rings.
  • Diamond Clarity: Blemishes and inclusions cannot be seen at the naked eye with a VS1 Clarity grade. While you can pay more for a higher Clarity grade, the different won’t be noticeable.
  • Diamond Color: To the naked eye, a diamond in the G to I range will appear colorless and will cost much less than those in the D to F range.
  • Online Diamond Engagement Rings Seller: Select only a well-respected diamond dealer with high quality certificates and years of experience. We recommend choosing from the James Allen, Brian Gavin Diamonds, or Blue Nile inventories.
