Why is Diamond Size Important?

You might have heard a lot about 4Cs of diamonds. The 4Cs refer to Carat Weight, Cut, Color, and Clarity. All these 4Cs are important to understand the value of diamonds. These are the four grades that give a statistical/quantitative analysis of the diamond. For instance, we have a diamond having a carat weight of 1.00, color grade D, clarity grade SI2, and ideal cut. The gradings show the specification of the diamond, and it is like a quantitative analysis. However, the main goal is to select a diamond that looks pretty and stunning.

The primary reason for grading is determining the value of the piece. It does not clearly represent how the diamond will look like. However, diamond experts might get some idea of the diamond after looking at these grades. People who don’t know much about diamonds get a clear idea of the diamond's look once they see the real picture or examine it physically.

In real life, the diamond's look is more important than its grades and specification. Any diamond that looks appealing to the eye is perfect, even if it is a bit small or has a slight yellow tint that is not visible to the naked eye. No one is going to measure your diamond, but everyone will judge it from its appearance. So, the most important thing that matters is the look of a diamond.

When it comes to the appearance and look of the diamond, the first thing that everyone notices is the size. The size is very important if you want to buy the right diamond. There is no doubt that the size of a diamond is not in the 4Cs, but it has a relation with the carat weight. In simple words, it is important for you to consider the size of a diamond if you want to get the best piece.

Carat Weight VS Diamond's Size

Many people, especially beginners, often get confused about the Carat Weight and Size. They often think that these two are the same. However, there is a big difference between them.

Carat refers to the weight of the diamond. It does not represent the size or the dimensions. It is a small unit of weight, which is specially used for diamonds.

1 Carat = 0.2 grams or 5 Carats = 1 Gram

With the help of carat weight, the value of a diamond is decided. While buying a diamond, you will definitely check the carat weight. However, people cannot see the weight of the diamond from the naked eye; they can only see the size.

The size of the diamond has a relation with the carat weight. Typically, a diamond having more weight will be larger than a diamond having less weight. It is self-explanatory that a 5-carat diamond would be larger than a 3-carat diamond.

The size of the diamonds depends on carat weight, but it does not mean that the size will always be the same for the same carat weight. For instance, there are two diamonds of the same carat weight, but one is shallow, and the other is deep cut. The shallow cut will look larger in size because it has a larger diameter and a smaller depth. In contrast, the deep one will look small because of its depth. Thus, there could be different sizes of diamonds having the same carat weight; however, the size won't differ too much. It is not possible that there are two diamonds having the same carat weight, but one is 3.5mm, and the other is 9.5mm in diameter.

Moreover, if there is a slight difference in the size of diamonds, you cannot notice anything. For instance, a diamond is 2.00mm, and the other is 2.03mm in diameter. The larger one will be pricier, but no one can notice the difference of 0.03mm. Both diamonds will look almost the same. Thus, you can save money by buying the smaller one in this case because there is no big difference.

Why is the Cut of a Diamond Very Important?

The cut of a diamond is quite important because the brilliance depends on it. If the diamond is cut well, it will sparkle due to reflection. But if it is not cut well, you won't notice the brilliance.

A diamond of 2.00 carat and excellent cut-quality is better than a 2.05 carat diamond with poor cut quality. You can go for a lesser weight because no one will notice it. Diamonds are known for their brilliance, so you need to give more importance to the cut-quality as compared to the diamond size and weight.

The diamond's cut quality also affects the size. Even if the carat weight of the diamonds is the same, they can differ in size because of the cut quality. The cut can be deep, shallow, or ideal. The ideal cut is the most preferred one because it has excellent brilliance. It is neither small nor too wide in size; it is in the middle of the shallow and deep cut. In contrast, the shallow cut has a larger diameter, while the deep cut has a smaller diameter.

Cut quality is not easy to understand because it depends on various proportions and percentages that experts know. It is too technical, but the buyer can understand the cut quality through GIA's five cut grades. The grades are Excellent, Very Good, Good, Fair, and Poor. You need to pick the right cut quality because it will determine the look of the diamond.

Diamonds Size Charts

There are different types of size charts that show the relation of the size of the diamond (diameter) and carat weight. We have already discussed that the size can differ because of the cut-quality, but the charts are made according to the ideal cut.

Moreover, there can be different charts for different shapes of diamonds. Mostly, you will see charts for round diamonds.

In the above chart, you can see the size of diamonds according to the carat weights. This is just to give an idea of the size according to the shape and carat weight. The size can differ slightly; it can be more or less.

How to Get an Idea of the Diamond Size?

It is very difficult for a buyer to get an idea of the size if he is buying online. It becomes difficult, and sometimes, the diamonds are smaller or larger than the expectations. To solve this problem, diamond sellers show the diamond sizes over the fingers. The diamonds are placed on the hand so that the viewer can compare the diamond size with the fingers. This gives a better idea of how the diamond looks.

Sellers also compare diamond sizes with standard coins. This is also an excellent idea to guess the size. There is usually a scale that shows different diamond carats and their sizes.

How to Select a Diamond?

Selecting a diamond is not as easy as it seems, but if you have proper knowledge of diamonds, you can easily buy the right piece according to your needs.

First, you need to look at the 4Cs of diamonds. All the Cs are important, but the carat weight and the cut are the most important ones. Then, you can consider the color and clarity. You can easily select the diamond carat weight according to your budget. After that, you need to select an ideal cut that can offer mesmerizing brilliance. While selecting the cut, if you need to go a little lower in the carat weight, you can do that. For example, if you want a 1-carat diamond, but the cut quality is ideal in the 0.98-carat diamond, then you should pick the 0.98-carat diamond. There won't be a visible difference in the size of these two diamonds. In simple words, you need to pay attention to the cut quality at every cost.

When you have a clear idea of the carat weight and cut quality, you can go for color and clarity. These both Cs are important, but as long as the diamond is appealing to the eye, you don't need to overpay for these grades. You don't necessarily need a D color diamond because F grade will also look the same. G-J grades are also excellent, and you won't find a visible color in G and I grades. So, if the color is not visible, you should go for these grades and save money.

Similar to color, clarity should also be according to the look of the diamond. An internally flawless (IF) diamond will have no inclusion, even under 10X magnification, but the real thing is that no one is going to see your diamond under a microscope. VVS1-VVS2 diamonds have inclusions, but they are not visible to the eyes. So, you can go for these diamonds and spend more on cut quality and carat weight.
