2.08 Carat Round Close Up Side

Imagine this – The engagement ring you are about to give your (soon-to-be) fiancé is dazzling right in front of you. Indeed, you will want to buy it. But choosing the right carat can be a daunting task.

A 2 carat diamond in a round shape should be approximately 8.10 mm in diameter. If you find a scale to measure this, you will be left with the same weight as half a raisin. Even then, it will depend on the usage, cut, and shape of the diamond. But, in general, it will weigh less than 400 milligrams.

Does it sound confusing, or maybe intriguing?

Either way, we will inform you about every aspect related to a 2 carat diamond. After reading this post, you are likely to gain proper insight and choose the right diamond for your beloved.

What’s a 2 Carat Diamond, and How Big is It?

We are not going to sugarcoat it – Shopping for a diamond can get incredibly confusing!

The weight of a diamond depends on its size, but it is not similar to the overall size of the ring. So, a 2-carat diamond is nothing but a rock that weighs 2 carats.

It means that you will have a 400-milligram weight or 0.4 grams on the hand. Well, to paint a better picture, such a diamond ring will have the same weight as a half-cut raisin.

These diamonds can have a variable appearance, meaning that they will either look smaller or larger. That depends on your intent of use, shape, clarity, and more.

So, if you are sitting next to a person wearing a 2 carat diamond ring, you will see its flamboyance. But it might not draw attention to the finger if the wearer is in a crowded street.

Even then, such a diamond is truly rare and stunning to behold. They have a beautiful sparkle that will display the aesthetics of the ring.

This image depicts how big a round 2 carat diamond ring will look like. Ideally, numerous factors influence its size due to the scarcity of this significant diamond.

For example, a 2 carat round excellent cut diamond with VVS1 clarity and J color will have a surface area of 7.91 × 7.99 mm. On the other hand, the same diamond having I color and VVS2 clarity with a very good cut will have a surface area of 7.8 × 7.89 mm.

Factors That Influence the Size of a 2 Carat Diamond

We have found three main factors that influence the size of a 2 carat diamond ring:

  • Shape and Cut: Every diamond comes in various shapes and cuts, alluding to its finesse, symmetry, and polish. But, the 2 carat diamond size greatly depends on its cut, as depicted below. For a 2 carat diamond, you should choose between good to ideal.
  • Color and Clarity: The clarity and color of the diamond you have chosen will significantly impact the overall size. It refers to the visual appeal of the diamond. You can select from VS2 to VVS1 clarity for a 2 carat. The best color range for your diamond can be from G to I.
  • Setting: The most important aspect that influences its size is the ring setting. Ideally, you can go for a 5 to 7 ring size which is the most common for 2 carats.

According to GIA, 2 carat diamonds are rare for the high quality they possess. Hence the price will also be more. They also suggest that the lesser color you choose, the higher grade of diamond you will get.

Tips for Buying a 2 Carat Diamond

According to Statista, the world mined over 142 million carats in 2019. Does this not allude to a huge demand for this precious rock? Proposing to your beloved with a huge rock can be special and truly beautiful.

Those who can afford a rare diamond ring usually go for a 2 carat one. These diamonds have a perfect display of sparkle and dazzle of aesthetics.

But their weight and size mean that a slight inclusion of poor cuts can be easily noticeable. Here are some tips that you can follow to make your engagement ring perfect.

Buy it Online

Buying it from James Allen or the Blue Nile should be your first choice. 2 carat diamonds are rare and local stores might not have the truest form. In case they do, you may have a limited selection available.

That is why we recommend that you go online and get your dream diamond.

Stick to a VS or Better Clarity

You can go for lesser diamond clarity when the carat is smaller. But we recommend that VS clarity or more would be ideal for a 2 carat.

It is due to the overall bigger diameter these diamonds possess. Hence, the black inclusions can be visible to the naked eye, and you wouldn’t want that.

Choose a G or Better Color

Choosing a color for diamonds is a subjective matter. Yet, larger diamonds like a 2 carat are color sensitive. So, they will shine brighter when you choose a G or better color.

If you do not, then you are likely to witness the undertones of yellow nuances.

Go for AGS and GIA Graded Diamonds

When looking for diamonds, make sure you find GIA or AGS certifications. These are gemological grading services that can assure the quality of your diamond.

Note: Never, and we mean NEVER buy diamonds certified by any other lab.

Optimal Cut, Clarity, and Color Rating for a 2 Carat Diamond

For a 2 carat diamond, we recommend getting a clarity grade of VS1, VS2, or above as it does not showcase any blemishes. The ideal color rating would be G to I as it ensures that the diamond appears colorless as seen by the naked eye.

Similarly, we recommend a good to very good cut for your diamond ring.
