How Big Is 2 Carat Diamond

A diamond is only as desirable as the amount of fire and brilliance it gives. That’s why diamond buyers usually exercise due caution when shopping for the right diamond size and weight. Indeed, the bigger the size and weight of a diamond, the more sparkle it gives. However, there’s an exception to this rule.

In fact, the brilliance of a diamond has a lot to do with numerous other aspects besides its sheer carat weight. But if all these other parameters were to be kept constant, you’d most probably opt for a 2-carat diamond than, say, a 1- or 1.5-carat stone. In this guide, we’ll explore everything there is to  know about a 2-carat diamond. In the end, you’ll be able to determine whether such a stone fits your needs after all.

What’s a 2-Carat Diamond and How Big Is It?

Simply put, a 2-carat diamond is a diamond that weighs 2 carats, or roughly 400 milligrams. To paint a clearer picture, a two-carat diamond weighs approximately the same as half of a raisin. Now, that might appear large or small depending on what you intend to use it for. For instance, a 2-carat diamond ring isn’t likely to draw any attention in a crowded street. However, the diamond can look significantly larger if the wearer is sitting right next to you on a place.

Certain professions, such as acting and modelling, often call for overt displays of flamboyance and glamor. As such, you’d be better off wearing a 2-carat diamond, or even larger. However, if you work a job where appearance doesn’t really matter, your best bet would be to buy a diamond weighing anything below 2 carats. Same goes for those who work dangerous jobs, such as truck drivers and deliverymen. In such cases, you would want to conceal the diamond as much as possible whenever you feel your security might be threatened.

However, choosing something as priceless and timeless as a diamond shouldn’t only come down to your profession. And as we shall find out, how big a 2-carat diamond looks also depends on numerous other factors. For instance, how the stone is set on a ring, its cut, color, and clarity.

Another thing worth noting is that 2-carat diamonds are quite scarce. You won't find them in your regular jewelry store down the block. And that element of scarcity alone adversely influences their price. Therefore, the best place to buy a 2-carat diamond is online. You will come across numerous online dealers offering elegant 2-carat stones at significant price variations. Buying a 2-carat diamond from a reputable online dealer is also up to 30% cheaper than buying the stone from a physical stone.

But costs aside, let’s narrow down our focus on how big a 2-carat diamond looks and how you can possibly enhance or diminish the size.


Factors That Influence the Size of a 2-Carat Diamond

The Diamond Shape and Cut

Diamonds come in various cuts and shapes. And how big a 2-carat diamond looks depends on the cut of the diamond. For a diamond to appear bigger than it really is, it must have excellent light-and color-handling properties. And these properties are primarily determined by the diamond cut.

For instance, a 2-carat  marquise cut diamond comes with a surface area of 13.08×6.54 mm while a trillion diamond has a surface area of 9.75×9.75 mm. On the other hand, a 2-carat  Asscher cut diamond features a surface area of 7.07×7.07 mm while the same 2-carat diamond measures 6.94×6.94 mm for princess cuts.

From this data, we can deduce that trillion and marquise cuts have better light-handling properties than their Asscher and Princess counterparts. Therefore, they create a better illusion of size. If you’re shopping for a 2-carat diamond but can’t seem to settle on the right cut, the question to ask yourself is how much of a sparkle you intend the diamond to give. For maximum brilliance, insist on cuts that come with greater surface areas. However, if the size and sparkle don’t appeal to you [which will unlikely be the case], you can settle for cuts that feature smaller surface areas.

But what truly makes some diamond cuts appear larger than others? As we’ve already mentioned, it all depends on how the diamond handles light and color. But that sounds more theoretical than practical.

When cutting and polishing diamonds, more focus is often placed on the carat weight of the stone, not necessarily its size. Diamonds that feature more facets and elongated sides tend to trap maximum light from their surroundings. The light is then focused onto the centerpiece stone, thereby making the stone look deceptively bigger.

But going by that concept, why do round brilliant cuts also feature among diamonds with super light-handling properties despite their apparent lack of angles. Well, that’s because the round shape implies the stone has an infinite number of facets. And the higher the number of angles, the better the light-handling attributes.

The following table illustrates the surface areas of  common diamond cuts.

Marquise cut

Pear-shaped diamond


Asscher cut


Emerald cut


Also, you should remember that there’s no linear relationship between the surface areas of diamonds based on their carat weights. For instance, assume the surface area of a 1-carat diamond is 66 square millimeters. That doesn’t necessarily imply the surface area of a 2-carat diamond of similar cut will amount to 132 square millimeters or thereabout.

Diamond Color and Clarity

Besides cut, the color and clarity of a 2-carat diamond have a significant bearing on the diamond’s overall size.

The  diamond color scale ranges from D to Z. D represents the most clear diamonds while Z represents diamonds with visible tints of brown or yellow.  Colorless diamonds have better light-handling attributes than the colored ones. As such, a 2-carat D-color diamond will look larger than a 2-carat K-color diamond, if the two stones are similar in all other aspects. But if you’re looking for a 2-carat colored diamond that appears deceptively large, insist on fancy colors. Examples are red and purple. Fancy colors absorb and reflect maximum light from their surroundings.

Regarding clarity, diamonds are generally graded in terms of the visible flaws and inclusions in them. The clarity chart ranges from Internally Flawless (IF) to Inclusions 2 (I2), with lots of variations in between. It’s generally observed that flaws in a diamond reduce its ability to absorb and reflect light. That ultimately influences how big the diamond looks.

The Size and Setting of the Engagement Ring

It would be ridiculous to go shopping for a 2-carat diamond without first understanding the right diamond ring size for you. Diamond rings are generally sized depending on the length of their diameters. For women, 5, 6, and 7 are the most popular diamond ring sizes. A size-5 ring has a diameter of 14.3 millimeters while a size-6 ring has a diameter of 14.7 millimeters. You must first establish your ideal ring size even before you can deal with the setting issue. That way, you won’t have to take the diamond back to the shop for resizing in the future. When it comes to the right setting, insist on a white color band. White reflects maximum light, hence will help accentuate the diamond in the ring. 

Experts also recommend going for thinner bands. The more invisible the band is, the more prominent the diamond will look. Most importantly, choose ring designs where the diamond is centrally-placed, and surrounded by pavé diamonds. The pave diamonds will trap maximum light and focus it onto the centerpiece, thereby enhancing the size of your 2-carat diamond.

A 2-carat diamond is big enough to be noticed. Even better, you can now enhance its size without necessarily increasing the carat weight. You only have to ensure you go for the right color, cut, and clarity score. Also, do your research on the ideal ring size for you, as well as the best ring setting for the diamond.
