Each diamond comes with a variety of properties that make them unique. In contrast, each diamond is machine cut as it is being processed and therefore the diamond size can be predicted. As a result of cutting, diamonds have a millimetric size corresponding to the weight of each carat.
There is a direct relationship between carat weight and size, and a diamond with a higher carat weight is larger than a diamond with a lower carat weight. Although there is a direct relationship between the two, the carat refers to the weight of the diamond, not the size of the diamond. The diamond size, measured in millimeters, is determined by the length-width and depth characteristics. The width, length, and depth of a diamond are measured in millimeters. However, there are different characteristics between the apparent size and the actual size of the diamond. Diamond size charts are comparative tables used to indicate the millimeter size of each diamond shape and the carat weight to which that size corresponds.
Each diamond shape may not have the same “carat weight X diamond size” value. The most common cut shape, round cut diamonds are less in-depth than most of the fancy (not round) diamonds. For example, the 1.00 carat round cut has a diameter of about 6.40 millimeters. On the other hand, the size of a princess cut that weighs 1.00 carats is about 5.50 millimeters. As you can see, fancy cuts tend to appear smaller than round cuts, even though they weigh the same in carats; This means that a round cut diamond is more expensive than other cut shaped diamonds.
Even expert gemologists may have a hard time noticing a 5% to 10% difference in carat weight, and this is why diamonds are weighed. The diamond can be cut shallow and wide to achieve a diamond that looks greater than its carat weight. The highest level of fire, shine, and sparkle of the diamond is associated with the ideal size of the diamond. Although the cut that is not ideal size allows us to obtain a larger diamond, the gloss level of the diamond may decrease.
Carat Affects Diamond Size
The unit of weight of diamonds is called “carat”, which comes from the weight of “carob” seed, a unit of measure used by diamond merchants, and the diamond is marketed in this unit of weight. Thus, a diamond weighing 1 carat corresponds to 0.2 grams. However, many people think that carat and diamond size are the same things. On the other hand, the “carat” used to express the weight of diamonds is not the same as the “karat” that indicates the purity of gold.
In the most general plane, the carat weight affects the size, but this effect is not as simple as it seems. Although the appearance of a 3-carat stone is larger than a 0.50-carat stone, this cannot be said for diamonds weighing 0.90 ct and 1.10 carats. Therefore, the important point here is that the features you should consider when choosing a diamond are the “measurements of the diamond.”
Therefore, even though it is 0.97 carats, it is not difficult to reach a diamond weighing 0.97 carats, which is larger than 1.00 carats and is more affordable than it, with its well-proportioned structure. It can be said that diamonds with these features are mostly seen among diamonds with non-round cuts. This is because the facet patterns of these diamonds are not very specific.
With the increase in the carat weight of a diamond, the diamond price increases at the same rate. This is because although the price depends on many factors, the larger the diamond, the rarer it is and therefore the more valuable. Less than a million mined rough diamonds are large enough to produce a refined 1-carat diamond. In other words, an increase in carat weight causes an increase not only in terms of the total price but also in the price per carat. Accordingly, the following comparison describes the usual relationship between diamonds that are equal in quality and their rising carat weight:
Carat Weight 1.00 carat 2.00 carat 3.00 carat
Price in Total $ 6,000 $ 24,000 $ 54,000
Price for Each Carat $ 6,000 $ 12,000 $ 18,000
The price of two diamonds with the same carat weight may differ not only based on carat weight but also in cost based on many diamond properties such as clarity, cut, and color. When choosing a diamond, it should be entirely up to your partner to decide how many carats your diamond should weigh. If the buyer has a certain size in mind, it is one of the most important factors to seek carat weight until you get that size. In this case, other factors should also stand out and be effective in your choice. Most women can express their ideal carat weight of their dreams and tell the shape of the diamond. Many men, on the other hand, can say something about the price of these diamonds.
Diamond Carat – Size Chart
Although the price of a diamond increases exponentially as a result of the increase in carat weight, it does not have to be an increase in its real size. There is a typical relationship between increasing carat weight and size. For example, when a diamond triples its carat weight, for example, 1 carat is 3 carats, the apparent size also increases three times in the crudest terms. In contrast, the diameter only increases by 45%, from 6.50 to 9.40, and the increase in the crown setting, which is the surface area, will slightly more than double when the crown area is set in the diamond setting.
When examining diamonds of any shape, one must take into account that a certain increase in diameter leads to a greater increase in a surface area called the crown area and overall size in terms of sight. Although a diamond is approximately 50% larger in diameter than another diamond, its appearance appears to have a diameter difference of more than 50%. To find out the diamond size in online suppliers, the criteria corresponding to each diamond should be carefully studied during the viewing of the diamond. The length and width characteristics of the diamond will guide you on how big the diamond is when viewed from above.
Even if two diamonds are the same shape and weigh in carats, these diamonds can differ in size based on the cut ratio. If the cut of a diamond is deep, the weight at that depth is considered “hidden” and has a large proportion of the total weight. As a result, if a diamond is cut well, it will have a smaller diameter due to its greater depth. The aforementioned differences in size can be noticed because they are evident, although there are small differences. Although the carat weight of this well-cut diamond is slightly lower than a deep cut diamond, it has a larger diameter and consequently appears larger.
Diamond Carat – Size Comparison
If two diamonds have equal carat weight, they may look very different in size and this is because of the shape of the diamond. For example, when comparing round and marquise-shaped diamonds weighing 1 carat, a marquise-cut diamond has a greater appearance than a round-cut diamond. So approximate size and length x width come into play.
Visually longer looking shapes such as pear, emerald, oval, and marquise tend to have a larger appearance to the eye than shapes that are more square and round in cut. The measurements, therefore, indicate the valid dimensions for diamonds weighing 1 carat and also perfectly cut, corresponding to each shape.
On the other hand, there is an area called the “crown”. This is the total surface area in terms of mm2. The crown area refers to the size, which is the area where a diamond appears when placed on the ring. For example, an oval diamond appears larger than a round cut diamond, while the actual surface area for both diamonds is the same; In other words, there is no such difference in reality, and it is just a perception.
On the other hand, an oval-cut diamond will not only look larger than a princess-cut diamond, but it will also have a larger surface area. So, the difference goes beyond just an illusion created by the shape that has an elongated appearance. The diameter of a diamond with a lower carat weight can be equal to the diameter of a diamond with higher carat weight, resulting in both appearing to be the same carat size.
Size of 1 Carat Round Shape Diamond
A diamond with a 1-carat weight and a round cut is approximately 6.5 mm in size. On the other hand, the shape, diameter, and cut quality of a diamond are all affected by the diameter of a diamond of this weight. For this reason, diamonds weighing one carat differ from 6,11 mm to 6.53 millimeters, and as can be seen, there is a big difference. The reason for this difference in size is that some diamonds have a deeper cut than others and hence the carat weight is embedded in the bottom of the diamond.
The millimetric sizes corresponding to the carat weights of the round shape diamonds are as follows:
Carat Weight Size of Diamond
0.25 carat 4.0 millimeter
0.5 ” 5.1 “
0.75 ” 5.8 “
1.0 ” 6.4 “
1.25 ” 6.9 “
1.5 ” 7.3 “
1.75 ” 7.7 “
2.0 ” 8.1 “
2.25 ” 8.5 “
2.5 ” 8.9 “
2.75 ” 9.0 “
3.0 ” 9.3 “
3.25 ” 9.5 “
3.5 ” 9.75 “
3.75 ” 9.9 “
4.0 ” 10.1 “
0.5 Carat Diamond
Just because a diamond weighs less than a carat does not mean it will appear small. Although it is related to the millimeter size, the criterion that depends on the size of the diamond, even if the carat weight is low, is the shape of the diamond and the shape you choose affects the size of the diamond. So, if your budget is suitable for a diamond that weighs less than one carat, be careful about the shape you choose.
If you want to have a diamond engagement ring with less karat and therefore a lower price, you should choose a round cut diamond or oval cut to make the ring look more flamboyant. So, what is the diamond shape that will appear smaller and therefore should not be chosen? These are emerald shaped diamonds.
1.0 Carat Diamond
A round diamond weighing 1 carat will also differ visually depending on the cut shape. Therefore, an Asscher-cut diamond will have a different look than it, even if it weighs the same as a princess cut diamond, for example. Typically, there is a direct relationship between the carat weight and the appearance of the diamond. Although this relationship applies to the round cut, the feature that affects other diamond shapes is not only the carat size but also the millimeter size.
1.5 Carat Diamond
If your budget is not enough to buy a diamond weighing 2 carats, you can choose a diamond weighing 1 and a half carats instead of 1 carat. One way that can be tried to make a 1.5-carat diamond look larger is to surround it with a halo or side stones. The diamond is surrounded by a halo, just like chest underwear with a push-up effect; therefore, it results in an effect that makes the stone appear one and a half times larger than its size.
2 Carat Diamond
A diamond weighing 2 carats has a special size. This size is the most ideal carat weight preferred by brides. Just like the brides, the betrothed usually plan to have a diamond ring between 1.5 carats and 2.5 carats. On the other hand, if you are going to buy an engagement ring, the biggest mistake you can usually fall into is getting into an impasse for insisting on high carat weight.
So, do not start the diamond jewelry selection business by always insisting on the biggest diamond; Instead, know that a diamond with a lower carat weight will also look good if it has pretty good properties. There are even diamonds that appear to be larger than 2 carats but weigh 1.9 carats. For this reason, if you act flexibly, you can get the diamond of the size you want but with less carat weight at a more affordable price.
2.5 Carat Diamond
If you want to buy a large size diamond if you desire a diamond that qualifies as “large size”, the carat weight for the diamond that qualifies as “large” starts at about 2.5 carats. In this direction, you want to know that the price of the diamond you will buy or buy with weight is appropriate. You should know that if the diamond is shallow rather than deep, this will result in a larger view than it is. In contrast, this shallow diamond often does not reflect light as well and does not look as bright. The deeper a stone is, the smaller it looks.
3 Carat Diamond
Buying a 3-carat diamond is a fairly serious investment, and therefore you want to be sure of everything and not have any hesitation, depending on other financially similar decisions. The best way to do this is by purchasing loose diamonds. For this purpose, you should opt for loose diamonds. Although settings affect the appearance of the diamond, you invest most of the investment in stone, not decor.
Factors Affecting the Apparent Size of the Diamond
There can be many factors affecting the apparent size of a diamond. These factors, such as shape, cut, setting, and even style, and many design elements, from the shape to the setting and style of a ring, can reduce or accentuate the apparent size of a diamond. For example, the halo setting surrounded by the diamond or other stones around the center diamond serves to emphasize the visible setting of the center stone. A set of three stones with side stones along with the center stone adds sparkle to the diamond.
As we mentioned earlier, an oval-shaped diamond has a longer shape and this looks larger than many shapes. But keep in mind that size is just one feature of a diamond and another diamond feature to focus on; Possible buyers, possible delivery buyers, not good styles and examples should be chosen because thin shapes such as Oval and Marquise not only have the same depth percentages as Round, but not with this, but have extra length; Therefore, choosing an Oval or Marquise-shaped diamond is a practical way to get a larger-looking diamond for less.
Diamond Shape Carat Weight Millimetric Size
Round 1.00 carat 6.5mm
Marquise 1.00 carat 10mm x 5mm
Oval / Pear 1.00 carat 7.7mm x 5.7mm
Just as some diamond shapes appear larger than others, some diamond shapes also tend to appear smaller than others. For example, the depth percentages are much higher as a result of cutting many shapes to be considered in square shapes such as Princess and Pillow. So, when compared to round diamond shapes, it is possible to say that these diamond shapes appear smaller than round diamonds, as shown below:
Diamond Shape Carat Weight Millimetric Size
Round 1.00 carat 6.5mm
Square Cushion 1.00 carat 5.9mm
Princess 1.00 carat 5.5mm
Asscher 1.00 carat 5.5mm
Diamond Size You Should Choose
You have attempted to choose the perfect engagement ring for someone special to you (your lover, your fiancee, your partner, or your family member), but you have questioned which diamond size ring to buy. In this case, you will need to do a series of research. On the other hand, the first thing that you should accept is that you choose the largest and highest carat stone that you can choose does not mean that you love the recipient of the gift very much.
Just like that, choosing a stone that is smaller and weighs less does not mean you love the recipient of the gift less. So, the big diamond of a diamond is not always a sensible choice, and the choice of the most complementary stone size for a ring is related to personal style, hand size, ring setting, and of course your budget.
The average engagement ring size will vary depending on where the recipient lives. For example, ideal for the central stone in engagement rings, and the most sought after, the size was 1.0-carat weight. However, the trend has changed a little more recently. These days preference is given to stones with a carat weight of just over 1 carat, so those who buy a diamond ring will choose a ring with a diamond weighing between 1.25 and 1.5 carats on average.
The lifestyle and career of the ring buyer are also of vital importance in choosing the size. If the owner of the ring is a teacher or a housewife or is engaged in a hobby such as sports or gardening that requires frequent use of his hands, a smaller or at most medium-sized stone is the appropriate size for the ring you will buy for him. It is also important whether the buyer is wearing any other jewelry. If he is wearing a larger size central stone can be chosen, but if he does not wear other jewelry, then the size to be chosen should be smaller and thus simpler following his style.
So how is your partner’s relationship with the diamond? Consider whether he likes diamonds or not. Although an environmentally conscious buyer may appreciate the diamond’s appearance, it takes care of the environmental and ethical issues that lead to the diamond’s origin. If your partner is someone with this sensitivity, you may care that the ring you will buy for him is a ring made of diamonds obtained artificially in the laboratory. These diamonds are nearly 100% identical to mined diamonds; however, these diamonds are obtained without conflict and are 40% less common than mined diamonds.

If the finger of the person you will gift the ring to is less than the size of the ring measuring 6.5, the diamond you choose should weigh 1.0 carats or 1.50 carats. On the other hand, if this person’s fingers are larger than the size of the ring measuring 6.5, you can choose a diamond up to 2.0 carats by increasing the carat weight. Make sure that the smaller the finger, the bigger the diamond will appear.
Do Not Compromise on Quality
It is a complete mistake to try to choose the largest stone by focusing only on the size of the stone. Besides the size, the cut quality of the diamond is more important than size in choosing diamond jewelry, especially diamond ring; because this factor is the factor responsible for the sparkle and shine, which are the main properties of diamond. Usually, the largest of the measuring stones are shallow in cut, causing the light to leak from below (causing the glare to disappear).
Therefore, make sure the ideal parameters are selected and then make checks to ensure the contrast/brightness balance. Evenly spaced dark areas and bright areas in your stone are important for the diamond to accurately reflect and refract light. So the goal is to choose a stone that has a large size and, just as importantly, a great cut.
