What Exactly Is A 2-Carat Diamond Ring?

When a diamond is referred to as being 2-carat, it could mean two things: the center stone is 2-carat in weight, or the ring’s total weight is 2-carats.

Let’s start with what a carat is and exactly how it is measured before we explain these two scenarios.


What Is A Carat?

You most likely have heard about a carat and a karat and are wondering what these two are. To start with, they are totally different things.

Karat (with a K) is the unit used to measure the amount of pure gold in relation to an alloy of metals in jewelry. All gold jewelry is normally stamped with the number of gold parts in it and you can see this number being suffixed by KT, K, or kt.

The carat we are dealing with in this guide is diamond carat (with a C). Carat is the unit used to measure how heavy or light a diamond stone is. 1 carat is equivalent to 200 milligrams; a carat is also the same as 100 points.

Weight or Size?

The commonest way of referring to diamond weight is whole number carats like ½, ¼, ¾, 1/3, etc. but you will also find some jewelers using points when referring to carat weight.

It is important that you get familiar with the point system of carat weighting as this has an impact on the price of diamonds.

For example, if you compare the prices of a 1.90pt carat center stone and a 2.00-carat center stone, you will see that there would be a very big difference in the price, although the difference in carat points is very small.

Most people think that carat refers to the size of the diamond and not weight. The size of the diamond measured on the crown is usually noted in millimeters.

2 Carat Center Stone

A diamond engagement ring that has a 2-carat center stone is going to attract a high price as long as the other 3Cs are sufficient. It is very possible to get a good deal on one diamond attribute, but that may also mean you have to sacrifice the other.

The ring below is one good example from James Allen


It is important that when you are shopping or when you finally assemble a ring of your choice, you verify the carat weight you see refers to the weight of the center stone and not the total weight of the diamond.

2-Carat Total Weight

When a diamond’s total cart weight is 2, it should bear the label 2TWD, but not every supplier puts the label.

Below are 3 different diamonds each with a total carat weight of 2. The center stones are princess cut each weighing 1.51 carats.


The diamond rings have varying carat weights and each has different dimensions. You can have a ring that has a total of 10 diamonds, each having 0.2 carats. This means the total carat weight is 2 carats.

The price of such a ring would be much less since the diamonds are of smaller sizes. The diamonds do not need high clarity too as a large diamond would.

For the sake of this article, we are going to use 2-carats with reference to the weight of the center stone.

Is A 2 Carat Diamond Cheap Or Expensive?

There are several factors that affect the cost of a 2-carat diamond. The most important factors are the 4Cs, developed by GIA.

In this guide, we talk about 1 C; Carat, and we already know carat affects a diamond’s price. Other factors that affect the price of a 2-carat diamond ring are:

  • Diamond cut
  • Diamond color
  • Diamond clarity
  • Diamond brand
  • Diamond shape
  • Diamond settings
  • Side stones

Diamond cut

Diamond cut can be used to mean either of two things: diamond shape, or how the diamond has been cut physically.

Let’s focus on the physical cut for now and save shape for later in this article.

The cost of a 2-carat diamond is greatly affected by how the diamond is cut. “Ideal” cut diamonds are the best-graded diamond cuts and will therefore cost a lot more than a “good” cut.

The rating scale for diamond cuts ranges from “poor” on the low side and “excellent” or “Ideal” on the high side. An ideal cut diamond has precise and exact proportions and symmetry.

This is the best cut for all diamonds. The perfect ideal cut is credited to Marcel Tolkowsky, who was a famous diamond cutter and mathematician.

The quality of cut in diamonds depends on three factors: the stone’s agility, cut design, and if the diamond is viewed from the crown.

  1. Cut design: This refers to how the weight of the diamond is distributed and its durability. If the weight is not properly balanced, the diamond becomes vulnerable which makes it susceptible to breaking or wearing down.
  2. Crown view: This helps when grading since the diamond grader can assess the level of light dispersion, scintillation, fire, and brilliance. When the diamond rates high in all these factors it obviously is a quality cut grade.
  3. How the diamond is crafted is important when it comes to its cut. A poorly polished stone or one with bad symmetry dimensions will make the diamond have poor brilliance making the ring look dull.

Tip: To know if a stone has a good cut grade, look at the thickness of the girdle. The girdle is the part of the diamond that separates the crown from the pavilion and it runs around the diamond.

A good cut grade is made of a girdle that is slightly thick or medium-thin, not thin.


Clarity is one of the other major factors that determine the price of a diamond. The standard scale for grading diamond clarity starts from I3 and goes up to FL with I3 being the lowest clarity and FL being the highest.

When a diamond has a flawless grade, it means you cannot see any natural blemishes in it. Diamonds that fall in this category are the most expensive, the highest quality, and the best cut.

Apart from a flawless diamond, the VS1, VS2, VVS1, and VVS2 are also eye clean but inclusions can be seen under a 10x magnification.

By now, you already know that diamond cut and clarity do not only affect the price but also determine a diamond’s worth and how easily it can be found.

Clarity is the main reason why a diamond with r carats may have different prices. With lower clarity grades the prices will also go down.

Below is a loose excellent cut diamond from James Allen. It is a 2-carat round cut diamond with SI1 clarity grade. This is slightly included clarity grade which actually means that you can see some traces of blemishes even without a microscope.

Then, there is this 2-carat diamond having VVS1 clarity. All its grades are similar to the one above apart from the clarity grade. There is a price difference of more than $26,000 between the two diamonds.

If you have decided to buy a 2-carat diamond ring, you should know better than to compromise on the clarity grade. In fact, the desirable clarity grade for a 2-carat diamond is VS1, at least on the minimum side.

If you gamble with clarity, you will see a lot of inclusions in the diamond, thus impacting the brilliance and beauty of your ring.


Among the 4Cs is the diamond color, also having a direct impact on the price of a diamond ring. The standard grading scale used measures the color of diamonds from light to colorless. The color of diamonds is normally identified by alphabetical letters between D and Z.

Read Here: Diamond Color Explained

Colorless diamonds lie in grades D, E, and F while light yellow diamonds start from grade L to Z.

When considering the color of your 2-carat diamond ring, you should think about the metal in which the ring will be set. For example, if you select a faint yellow color for the diamond, it will not look so yellow when put in rose gold or yellow gold.

When you put a diamond stone in dark metal, it will obviously look like it has lost a bit of its pigment.

Similarly, if you take a diamond with color grade K and put it into platinum or white gold setting, the diamond will look a bit yellow because of the silver color in the metal.

The other thing you are going to consider is if the 2-carat diamond ring you want comes with other stones. With a solitaire, you only have to think about the setting when it comes to pigments.

However, if there are other stones and especially big ones, you need to make sure all stones are the same color in all the diamonds. If the stones have a different color from the 2 carats at the center, it will distract attention from the center.


You may be thinking that all diamond shapes carry the same price tag, but that is not the case.

The most expensive diamond shape is the round brilliant diamond. Its price is contributed to by the high level of fire and brilliance it has. Round brilliant diamonds are also the most bought diamond shapes in the market, accounting for about 70% of the sales.

All the other shapes you see in the jewelry store are called fancy shapes. Fancy shaped diamonds are about 43% cheaper than round cut diamonds.

There are several diamond shapes that jewelers use to design diamonds. Some of these shapes are commonly used as side stones or accents.

Check out the price difference in 1-carat fancy shaped stones from Blue Nile.


There are certain diamond shapes that have a greater risk of breaking and chipping. Such shapes include trillion, marquise, and pear.

Because they can easily chip, these diamond shapes are cheap. There is also another popular shape called princess but is cheaper than round brilliant shapes.

Tip: The cushion cut is the third most common diamond shape. It is also among the low priced pieces in the jewelry market.

Brilliant cut diamonds like round shapes are more expensive than step-cuts like Asscher and emerald cuts.


Different ring designers price their 2-carat diamond rings differently. Brands that have built a name over the years are more expensive than those which are just starting. The quality of rings from such designers is always as good as those sold by fine jewelry retailers.

Some brands will make you pay more for a ring just because of their names although this should not be the case. Good examples of such designers are Vera Wang and Neil Lane.

Neil Lane is a vintage rings brand while Vera Wang decided to venture into Bridal jewelry after making a wedding dress for a long time.

These two designer labels know nothing about cutting diamonds. Their work involves assembling the diamonds. However, they are the most sought after ring designs in the jewelry market.

These brand names do not use any special technique when putting together diamond rings but they put a hefty price on their 2-carat diamond rings. In fact, you can buy the same 2 carat diamond ring at a much cheaper price at online jewelry stores like Blue Nile and James Allen. You even get to choose your preferred loose diamonds.

If you are so much into brand names, you should do extensive research on which brand name sells quality diamonds. If you buy from Leo or Tolkowsky, you are sure of getting something good as their diamonds are priced depending on cut and quality and not the name of the brand.


The price of a two-carat diamond is also controlled by its setting. In general, the ring price should not increase or decrease if it is set in gold metal whether rose, white or yellow.

However, if you choose platinum metal, the price will definitely increase. Platinum is more expensive than gold. Go to James Allen and check out the prices of this vintage pear diamond ring that is 2 carat. The ring costs $225 more if set in platinum than when in gold.


The price of platinum goes up because it is more durable than gold. If you go to a retailer that presets diamond rings, you will find that not all rings get to be set in platinum.

Tip: you can still get rind durability without spending so much on a platinum setting. All you need to do is to put a platinum head on the ring, this way the prongs will last longer than if it were just gold.

Other than the type of metal, the style of the setting also affects the price of a 2-carat diamond ring. Milgrain style diamond rings are the most expensive. Look at the milgrain ring shown below:


Other stones

A 2-carat diamond ring will also be affected by the side stones it has when it comes to its price. The price of the ring will be negotiable if you choose a solitaire, but if you go with a 3-stone ring, be prepared to spend a lot more.

If you choose several small stones in a halo setting, you have to meet the cost of those additional stones. This could be a good option for you since small diamonds are usually not expensive, you will not sweat about this.

As you have seen, the price tag you see on a2 carat diamond ring in the jewelry store is based on several factors but the main are color, cut, and clarity. Generally, the price of a 2-carat diamond lies between $5,000 and $50,000.

Watch the video below to learn about the difference in prices in relation to diamond size in different carat weights.


Is A 2 Carat Diamond Ring Big?

You can tell whether a 2-carat diamond ring is big or not by looking at its shape. Since the carat of a diamond does not represent its size, the table surface area of a stone with a fancy shape will look bigger. A good example is the emerald cut.

A princess-cut and an emerald cut will appear bigger than a round brilliant. Many people consider a 2-carat diamond to be a great carat size and a large diamond.

If you have big fingers, the diamond ring will look smaller particularly if you choose a solitaire.

What Is The Resell Value Of A 2 Carat Diamond Ring?

A diamond ring will never be sold for the same price it was bought at, regardless of the size. It is important that you buy a diamond ring to enjoy its beauty and have a chance to wear rare jewelry not to hold it as a financial investment.

If you resell your 2-carat diamond ring, you are likely to retain between 30% and 70% of the original value of the ring. This will also be the case if you have a diamond that has a high clarity grade like VVS2, VVS1, VS2, or VS1, you can still retain almost the same amount.

The resell value can greatly be interfered with if the diamond has poor quality standards.

Instead of thinking about how much you can resell the diamond, why not think about the sentimental value attached to the ring. You can think about passing it to your child as an inheritance instead of selling it.

A 2-carat diamond ring can be the best heirloom you can own and may even increase in value as the years pass.

Getting the Best Value When Purchasing a 2 Carat Diamond Ring

We already know all the factors that affect the price of a diamond ring; as a result, we should be able to buy a ring with hopes of getting the best value.

Getting the best value involves getting a diamond ring that has a GIA or AGS certificate. You stand to gain if you add a GemEx certificate that shows the brilliance and light effect of the diamond. By having these certificates you rest assured that the diamond you get is actually what the seller claims it is.

Diamonds that do not have grading certificates are not worth trusting because they do not tell you the exact grades of the diamond; some do not even say anything at all. Some diamond grading labs give a general range of diamond color, clarity, and carat. That is why it is good to custom design your own 2-carat diamond engagement ring so that you are sure of what you are paying for.

Closing Remarks about a 2 Carat Diamond Ring

We hope that you now know more about jewelry than when you started reading this guide. We hope that you know a thing or two about choosing the best 2-carat diamond ring for you. You know what to expect when it comes to prices and factors that affect the price.

Remember not to compromise the cut and clarity of the ring and thus you should ensure the ring’s quality is certified by GIA or AGS.

Apart from diamond grades, ensure you choose a diamond engagement ring that best suits the person you are going to give. Beauty should be an important factor as diamonds represent the beauty of love, so consider that when picking a 2-carat diamond ring.
