This extraordinary 2ct round solitaire diamond ring from Blue Nile illustrates the classic elegance of this carat weight. 

But looking for a 2 carat diamond ring may seem overwhelming.  In this ultimate 2 carat ring buying guide, we’ll walk you through each of the 4 C’s of diamonds with the information pertaining to this specific carat weight and also teach you tips and tricks to make the most of your budget and land on the ideal, high-quality diamond for you.

What is a 2 Carat Diamond?

Carats are often mistaken for a size measurement.  In truth, carats are the standard of measurement for weighing precious stones.  A 2 carat diamond weighs about 400 milligrams.  Since diamonds are cut by carat weight you can expect the surface area to vary among the different diamond shapes.  See the chart below for the dimensions and face-up size of the various diamond cuts.

Shopping online jewelers like Blue Nile, James Allen and With Clarity is usually your best bet when it comes to finding the best selection of 2 carat diamond rings.  These reputable online jewelers offer tools like filters, reviews, videos and high-definition images that make it easy to pick a ring. They also make it easy to combine different settings with the stone of your choice, so you know the final ring will look exactly like you expect.

 TIP: Keep in mind that lower color and clarity grades can still look beautiful and offer great savings. However, if a two carat diamond is out of your budget, a 1.5ct stone will still look large and cost less. Learn more about what carat diamond to choose.

How Much is a Two Carat Diamond?

Two carat diamonds vary widely in price. The chart below should help you understand how diamond shape impacts price.

H color, VS2 diamonds will appear white and eye-clean for any diamond shape, so they’re a good choice for price comparison. Prices are based on Blue Nile’s diamond inventory. 2021 prices are comparable to the 2019 data.

This chart is limited to H color, VS2 diamonds, so two carat diamonds can be more or less expensive depending on the color and clarity grade.

TIP: The price difference between round diamonds and fancy shapes is always significant. You could save thousands of dollars if you’re considering a fancy diamond shape, read about their pros and cons.

Cut Quality in a Two Carat Diamond

For any two carat diamond, you’ll want to find one with fantastic cut quality. Although a poorly cut two carat diamond will still have some sparkle, you’d be better off opting for a smaller, well-cut diamond. The smaller one will perform better and can actually appear larger!  So, if the two carat mark is of utmost importance to you, do not compromise on the cut.

While judging cut quality for fancy shapes is somewhat subjective, evaluating round brilliant diamonds is almost a science. If you’re looking for a round diamond with the best sparkle, limit yourself to “excellent” or “ideal” cut grades and stick to the parameters in our guide.

Although this recommendation will help you find a fantastic diamond online, you’ll still need to look at videos of your diamond. As an example, take a look at the video of this two-carat diamond on the Blue Nile site. Make sure that the stone has good sparkle throughout. Look at the brilliance (white flashes) and dispersion or fire (colored flashes) in the diamond. A well-cut diamond should have a good mix of both, but you may prefer more fire or brilliance.

Choosing Color and Clarity for a Two-Carat Diamond

For a two carat diamond, an SI1 clarity grade is still likely eye-clean. If you opt for a higher clarity grade, you’ll be paying extra for quality that you can’t appreciate without a microscope.

Be sure to check for large, dark spots under the table, which can be seen with the naked eye. If you’re not sure, it’s better to play it safe and try for a higher clarity grade. Those on a tight budget should be able to find an eye-clean, SI2 clarity, two-carat diamond, which can save you some money.

For color, an I or J will still appear white against white gold or platinum.  This 2 carat emerald cut ring from Blue Nile illustrates this point perfectly.  A K or L color could work for yellow gold or rose gold settings as seen in this 2 carat solitaire diamond ring from Blue Nile. While higher color grades will appear marginally whiter, it’s not very noticeable — try telling the difference in our quiz.

Also take a look at the setting to see what color the prongs are, since this will impact how the diamond appears in the ring.

Although you can find diamonds with lower color grades that “face-up” whiter, trying to save money by compromising on color is a gamble. Still, if you enjoy a warm tint, then opt for a lower color grade.
