How to Calculate Diamond Carat Weight by Size Measurements

What Is a Carat and How Much Does It Weigh?

Carat is a unit of weight, commonly abbreviated as “ct”. It is often used to express the weight of diamonds and other gemstones.

One carat is equal to 200 milligrams, or 0.2 grams.

An important fact to keep in mind is that carat weight is not the same as size or volume.

Different gemstones have different densities, and this is why a 1-carat diamond will not necessarily be as big as another gemstone that is also 1 carat in weight.

Diamond Carats and Points

Points, just like carats, are units of mass commonly used to measure the weight of diamonds and other gemstones. One point is equal to 1/100^th of a carat. So, it follows that one point equals 2 milligrams, or 0.002 grams.

Diamond Size

Broadly speaking, diamond size refers to the height and width of a particular stone, as well as the measurements of some of its key parts. The dimensions customers are usually most interested in are the size of the stone’s top and the key proportions that determine the quality of the diamond’s cut.

The reason the size of a diamond’s top is so important is simple: This part is the most visible when the stone is set in a piece of jewelry. On the other hand, having more depth in a diamond won’t do much for how big it looks in a setting as that additional size will be hidden in the mounting.

The overall proportions of a diamond’s cut are also important because they determine how the stone will reflect light and how much brilliance the diamond will exhibit as a result.

Diamond Size vs. Carat Weight: They Are Not the Same

Carat simply refers to how much a diamonds weighs, whereas size is about its dimensions. Hence, two stones of the same carat can have different dimensions and thus be of different sizes.

Conversely, you can have stones with either the same diameter or the same depth, for example, and these diamonds can still have different carat weights.

What Affects Diamond Size?

While it is true that carat weight puts a certain limit on a diamond’s dimensions, the factor that affects them the most is the stone’s cut. Some diamond shapes require the stone to be cut shallow, while other cuts are deeper.

For example, emerald-cut diamonds are rectangular and shallow by design, whereas round cuts and princess cuts have more depth.

Stones of the same cut and carat can also have different sizes depending on how the cutter decided to shape their proportions.

For example, two 1-carat round diamonds can have different widths or heights. And even if these two stones weigh the same, the deeper one will appear smaller when set in a ring, while the shallower diamond will seem larger.

How Diamond Size Affects Carat Weight

By varying the size of certain parts of a diamond, the jeweler cutting it can end up with a heavier or lighter stone.

For example, if there are two round diamonds with the same diameter, and one of them is cut deeper and with a thicker girdle, that stone will be heavier.

The deeper diamond could be more expensive just because it weighs more, although from the top, it won’t look bigger compared to the shallower stone.

Calculating a Diamond’s Weight in Carats

To calculate the carats of a diamond, simply weigh the stone, and record its weight in grams. Then, divide that number by 0.2 to obtain the carat weight of the diamond.

For example, if a diamond weighs 0.1 grams, then dividing this number by 0.2 yields 0.5, meaning that the stone weighs half a carat.

Check out this diamond search engine, where you can filter loose diamonds by carat, price, cut, color, and clarity.

To measure the weight of the diamond more precisely, it’s best if you use a sensitive scale that can measure milligrams. Then simply divide the weight of the stone in milligrams by 200. For example, if the scale shows 263 milligrams, this is equal to 1.315 carats (263/200). Dividing the number after the decimal point by 100 will give you the points of the diamond. You can see that the number after the decimal point is 315, and dividing it by 100 yields 31.5 points. From this example, the mass of a diamond that weighs 1.315 carats can be expressed as 1 carat and 31.5 points.

Conversely, to calculate the weight of a diamond in milligrams from carats, multiply the carat number of the diamond by 200 to obtain its weight in milligrams. So if the diamond weighs 1.62 carats, this results in 324 milligrams (1.62 carats x 200), or 0.324 grams.

Estimating Diamond Carat Weight by Measurements

Converting grams and milligrams to carats is straightforward, but what if you don’t have a scale? Actually, if you know some key measurements of a diamond, you can estimate its carat weight.

For round diamonds, you can use the following formula to estimate their carat weight:

Weight in carats = Diameter in mm x Diameter in mm x Depth in mm x 0.006

You can use the same formula to estimate the carat weight of oval diamonds as well.

For square and rectangular cuts, such as the emerald cut, the Asscher cut, the princess cut, the radiant cut, you can use the following formula:

Weight in carats = Length x Width x Depth x Coefficient

The value of the coefficient depends on the length-to-width ratio of the stone, and we’ll see what these values can be in a more detailed explanation further below.

All these formulas will give you estimates that are only approximate. If you want to get an exact value for the carat weight of a diamond, you need to weigh it on a scale, preferably one that shows milligrams.

Now, let’s take a look at how the size of a diamond converts to carat weight for some of the most common diamond cuts.

Conversion Table: Millimeters to Carat Weight for Round-Cut Diamonds

Here is a conversion table showing the estimated carat weight for the most commonly sold round diamond sizes.

To use the table, first measure the diameter of your round diamond, and then find the value to the left that is closest to the diameter you’ve measured in millimeters; the value to the right is the approximate carat weight corresponding to a diamond of the respective size:

• 4.1 mm – 0.25 ct
• 4.4 mm – 0.33 ct
• 5.1 mm – 0.50 ct
• 5.8 mm – 0.75 ct
• 6.4 mm – 1.00 ct
• 6.9 mm – 1.25 ct
• 7.4 mm – 1.50 ct
• 7.8 mm – 1.75 ct
• 8.1 mm – 2.00 ct
• 8.8 mm – 2.50 ct
• 9.3 mm – 3.00 ct
• 9.7 mm – 3.50 ct
• 10.4 mm – 4.00 ct

*(1 ct = 200 mg)

Estimating the Carat Weight of a Round Diamond by using a Formula

You can also calculate the approximate carats of a round-cut diamond with the following formula:

Carat Weight = Diameter x Diameter x Depth x 0.006

The diameter of a round stone is the length of an imaginary line that goes through the stone’s center (as seen when looking at the diamond from the top) and connects two points that are across from each other on the stone’s girdle (edge).

The depth of a round-cut diamond is measured as the distance from the stone’s top facet (the table) to the point at the diamond’s bottom (if there is a facet there, it is called “the culet”).

For example, if you have a round diamond with a diameter of 6 mm and depth of 3.5 mm, then the weight of the stone can be estimated in the following way:

6 mm x 6 mm x 3.5 mm x 0.006 = 0.76 ct

This result should be viewed simply as an approximation, as the actual carat weight of the stone may vary by at least 5-10% in either direction, i.e., the stone’s real weight can be anywhere from 0.70 ct to 0.80 ct.

Estimating the Weight of an Oval Diamond Using a Formula

The weight of an oval-cut diamond can be estimated using the following formula:

Carat Weight = Diameter x Diameter x Depth x 0.006

If you are wondering how the diameter of an oval stone should be calculated for the purpose of this formula, here’s the way it works: Just add the width and the length of the stone, measured at its widest and longest part respectively, and divide the result by two.

For example, an oval stone with measurements of 6 mm and 4 mm will have a diameter of (6 + 4)/2 = 5 mm.

The depth of a diamond is the distance from its top to its bottom (the bottom is defined as the point, or the single facet, farthest from the top).

So, if an oval diamond has a depth of 3 mm and a diameter of 5 mm, its estimated weight will be calculated as follows:

5 mm x 5 mm x 3 mm x 0.006 = 0.45 carats

This calculation is not very precise, but it is good enough to give you an idea of the approximate weight of a diamond.

In the above example, it is recommended that you interpret the result in terms of a range, i.e., the diamond’s true weight should be assumed to be 0.45 ct +/- 10%, or somewhere between 0.40 and 0.50 carats.

Millimeter-to-Carat Conversion Table for Oval Diamonds

In the table below, you can see how some of the most common oval diamond measurements convert to carat weights.

On the left, you have combinations of length and width, in millimeters.

On the right, you have the corresponding estimated carat values for the respective measurements:

• 5.0 x 3.0 mm – 0.25 ct
• 6.0 x 4.0 mm – 0.50 ct
• 7.5 x 5.0 mm – 0.75 ct
• 8.0 x 5.5 mm – 1.00 ct
• 8.5 x 5.5 mm – 1.25 ct
• 9.0 x 6.0 mm – 1.50 ct
• 10.5 x 7.0 mm – 2.00 ct
• 11.5 x 7.5 mm – 3.00 ct

Keep in mind that this conversion table assumes a fixed depth value for each length-width combination, so the actual carat weight for each measurement may vary depending on the actual depth of the stone.

This is why you should use the table only to get an approximate idea of where your stone stands in terms of weight and use the oval diamond weight formula to get a more precise estimate.

Estimating the Weight of a Princess-Cut Diamond with a Formula

Princess-cut diamonds have a rectangular shape, and most such stones are square (or approximately square), i.e., all their sides are equal.

The most important dimensions of a princess-cut diamond you should be familiar with are its length, width, and depth:

• The length and the width of a princess-cut stone are measured along the girdle, which is the widest part of the diamond.
• The depth of a princes-cut diamond is the vertical distance from its flat top (the table) to its bottom.

These are the measurements you need to know in order to estimate the weight of a princess-cut diamond. Let’s see how this is done.

The formula for calculating the carat weight of princess-cut diamonds is the following:

Weight (ct) = Length (mm) x Width (mm) x Depth (mm) x Coefficient

You already know how the length, width, and depth of a princess-cut stone are defined and how to measure them.

What you also need to know is how to calculate the value of the coefficient, which depends on the length-to-width ratio of the diamond.

To figure out the coefficient value, divide the length of the diamond by its width, and then find below the value that is closest to the result you got:

• Ratio closest to 1.25: Coefficient = 0.0080
• Ratio closest to 1.50: Coefficient = 0.0090
• Ratio closest to 2.00: Coefficient = 0.0100
• Ratio closest to 2.50: Coefficient = 0.0105

After you’ve determined which of the ratios above is closest to the length-to-width ratio of your diamond, use the corresponding coefficient in the formula to estimate the stone’s weight.

A worked example:

Suppose you have a princess-cut diamond with a length of 5.5 mm, width of 5 mm, and depth of 4 mm.

Its length-to-width ratio will be equal to 1.1 (5.5/5), and the coefficient value will be equal to 0.008. Using the formula, this is how the carat weight of the stone will be calculated:

Weight = 5.5 x 5 x 4 x 0.008 = 0.88 carats

Most princess-cut diamonds have square dimensions, or ones that are very close to square, so in most cases, their length-to-width ratios will be close to 1, and the coefficient you will need to use will be equal to 0.008.

Don’t forget that this formula gives you only an approximation of a diamond’s carat weight, so be aware that you will need to factor in some margin of error when interpreting the result.

Millimeter-to-Carat Conversion Table for Princess-Cut Diamonds

If you want a quick way of estimating the weight of a princess-cut diamond, you can reference a millimeter-to-carat conversion table.

The one below contains the most common diamond carat weights and shows what side length corresponds to each carat value.

These values are for square princess-cut diamonds that have a square outline, i.e., their length-to-width ratio is equal to 1.

Just measure the side of your square princess-cut stone, and find in the table below the carat value (on the right) that corresponds to the millimeter size (on the left) closest to your measurement:

• 3.5 mm – 0.25 ct
• 4.4 mm – 0.50 ct
• 5.0 mm – 0.75 ct
• 5.5 mm – 1.00 ct
• 6.0 mm – 1.25 ct
• 6.4 mm – 1.50 ct
• 7.0 mm – 2.00 ct
• 8.0 mm – 3.00 ct

The values in this table are calculated assuming a certain proportion of the depth of the stone to its length, but your diamond won’t necessarily have the same dimensions. So, use these values only as a general guideline – they are not meant to replace a more precise calculation.

Estimating the Weight of Emerald and Radiant Cuts by Using a Formula

As with the princess cut, you can use a formula to estimate the carat weight of a diamond with an emerald or radiant cut. The process is pretty much the same as with the princess cut.

All you need to know are the stone’s length, width, and depth (distance from its top to bottom), and you can input them in the following formula:

Carat Weight = Length x Width x Depth x Adjustment Coefficient*

*As already mentioned, the value of the Adjustment Coefficient used depends on the length-to-width ratio of the measured stone.

To calculate the length-to-width ratio, simply divide the length of the stone by its width, and find the resulting ratio in the table below to determine the Adjustment Coefficient you will need to use:

• L/W Ratio = 1.25 => Adjustment Coefficient = 0.0080
• L/W Ratio = 1.50 => Adjustment Coefficient = 0.0090
• L/W Ratio = 2.00 => Adjustment Coefficient = 0.0100
• L/W Ratio = 2.50 => Adjustment Coefficient = 0.0105

(If the value of the Adjustment Coefficient you calculated is not exactly equal to one of the listed in the table, use one of the above values that is closest to your calculation.)

For example: if an emerald-cut diamond has a length of 6.25 mm, width equal to 5 mm, and depth of 3.5 mm, its length-to-width ratio will be 1.25 (6.25 mm divided by 5 mm), and the coefficient you need to use will be 0.0080.

Thus, the estimated carat weight of this diamond will be equal to 6.25 x 5 x 3.5 x 0.0080 = 0.875 carats.

Keep in mind that the results obtained through this method are not likely to be very precise, so factor in a margin of error of at least 10-15%.

Estimating the Carat Weight of a Heart-Cut Diamond with a Formula

The approximate weight of a heart-shaped diamond can be estimated by plugging the stone’s length, width, and depth into the following formula:

Carat Weight = Length x Width x Depth x 0.006

The length of a heart-cut diamond is defined as the distance from its pointed end to the farthest point on the stone’s cleft side.

The width of such a stone should be measured at its widest part.

Depth is simply the distance from the lowest point at the bottom of the stone to its topmost facet.

Example: Suppose you have a heart-shaped diamond whose length is 5 mm, and it width is equal to its length.

If the depth of the stone is 3 mm, then its approximate carat weight can be estimated as follows:

5 mm x 5 mm x 3 mm x 0.006 = 0.45 ct

When interpreting this result, you shouldn’t view it as precise. In fact, it is recommended that you allow for an estimation error of about +/- 10-15%. So in this case, the actual weight of the diamond should be expected to be in the 0.40-0.50 ct range.

Millimeter-to-Carat Conversion Table for Heart-Shaped Diamonds

A quick way to figure out where your diamond stands with respect to carats is to use a conversion table that tells you what weight approximately corresponds to certain measurements.

This method is less precise than using a formula but works ok if you just want to get an idea of whether your stone is closer to 0.5 carats or 1 carat, for example.

In the table below, you have length and width measurements on the left (the table assumes that the length and width of a heart-shaped stone are equal, which they often are, even if approximately).

Measure the length and width of your diamond, and in the table below, find the measurements that are closest to your results.

On the right is the approximate guessed value of your stone’s weight:

• 4.2 x 4.2 mm – 0.25 ct
• 5.4 x 5.4 mm – 0.50 ct
• 6.0 x 6.0 mm – 0.75 ct
• 6.7 x 6.7 mm – 1.00 ct
• 7.1 x 7.1 mm – 1.25 ct
• 7.6 x 7.6 mm – 1.50 ct
• 8.3 x 8.3 mm – 2.00 ct
• 8.5 x 8.5 mm – 2.50 ct
• 9.5 x 9.5 mm – 3.00 ct
• 10.0 x 10.0 mm – 4.00 ct
• 11.0 x 11.0 mm – 5.00 ct

Use the above table only to make a rough estimate. If you want results that are a little more precise, then use the formula.

Use all the above conversion values only as rough guidelines, and don’t forget that the weight of individual stones can deviate from the estimated weight because cut proportions inevitably vary among stones.

These tables are also not useful for determining the weight of stones other than diamonds, as they will have different densities and hence, different weights.

Let’s take a closer look at the actual size of a one-carat diamond and see how big it looks when put on the hand, in a ring’s setting.

Diagram showing the approximate actual size of a ring with a 0.75-1.00-carat diamond

What Is the Size of a 1-Carat Diamond?

Carat is a measure of weight, and one carat is equal to 200 milligrams, or 0.2 grams.

How big a one-carat diamond looks will depend on its dimensions.

These dimensions, in turn, depend on the cut of the stone.

Click here to take a look at a selection of 1-carat round diamonds and their prices.

Let’s take a look at the approximate measurements a one-carat stone has depending on its cut:

• Round cut: around 6.5 mm in diameter
• Square princess cut and Asscher cut: approx. 5.5 mm long on the side
• Emerald cut (rectangular): around 6.5 mm long by 5 mm wide (these sides can vary)
• Radiant cut and cushion cut: approx. 6.0-6.5 mm by 5.0-5.5 mm
• Oval cut and pear cut: around 8.0-8.5 mm in length and 5.0-5.5 mm in width
• Marquise cut: approx. 10 mm long and around 5 mm wide

Keep in mind that all these figures are approximate and actual size can vary depending on the proportions of the particular stone.

Carat Weight, Size, and Diamond Prices

Carat weight is an important price determinant, and since bigger diamonds are rarer, their price per carat is higher. So it is understandable that a jeweler will try to cut a diamond in dimensions that increase its carat.

However, diamond cutters don’t have unlimited leeway when it comes to deciding on a stone’s size.

This is because tweaking diamond dimensions to increase carat after a certain point can result in a disproportional cut that gets a poor quality rating.

And since cut quality is also a major price factor, cutters try to balance carat weight and proportions by finding the right size that will yield the best price for the stone.

Should You Focus More on a Diamond’s Size or on its Carat Weight?

When choosing a diamond, a lot of people look for the biggest stone for the best price they can get.

Although it is understandable that you may want your diamond to be as visible as possible, you shouldn’t forget that it also needs to be the right size – i.e., the stone should have the right proportions.

The more proportional the cut of a stone, the more brilliance and sparkle it will have. Poorly cut stones let most of the light entering them leak out and end up looking dull and drab.

For example, a round diamond that is cut very shallow may look really big when set in a ring, but since the stone lacks depth and has a poor cut, the diamond will not have much brilliance.

So, when looking at the size of a diamond that you are about to buy, you should always check its cut grade.

Look for diamonds that will have a reasonably sized visible area when set in a mounting while also having a high-grade cut. Big but poorly cut stones are just not worth it.

How to Make a Diamond in a Ring Look Bigger

There are several factors that affect how big a diamond looks when mounted in a ring: the type of setting, the stone’s cut, and its shape.

How the Ring Setting Affects Diamond Size

Some ring settings leave more of the diamond visible compared with others.

For example, prong settings do not cover as much of the stone’s surface as bezel or channel settings.

A mounting that holds a diamond with four or six prongs can be a good choice if you want to show off as much of your stone as possible and make it look bigger.

Diamond Shape and Its Impact on Size

Some diamond shapes tend to look bigger than others, even if they are of the same carat weight.

If you want to create the illusion of size, look for shapes that are wider as opposed to ones that are long and thin. For example, a square Asscher-cut stone will look bigger than a narrow marquise-cut diamond.

Click here to see a collection of 1-carat-ish Asscher-cut diamonds.

When it comes to the appearance of size, shape doesn’t tell the whole story, however.

Sometimes, the way a diamond is cut can make it look smaller even though its shape looks wide and square. This is why you have to also consider the importance of cut.

Cut as a Factor in Diamond Size

The way a diamond is cut can greatly affect how big it looks. In general, cuts that are designed so that they are deeper tend to look smaller compared with shallower cuts, assuming the stones being compared have the same carat weight.

For example, the princess cut has more depth compared with the emerald cut.

In general, if you want a diamond whose surface looks larger when set in a ring, look for stones that are cut shallow.

Don’t forget, however, that each cut has certain ideal proportions, and if the depth of the diamond you buy deviates dramatically from the standard for the particular cut, the brilliance of the stone may be diminished.

This is particularly true of brilliant cuts such as the round cut.

Diamond Size and the Size of the Fingers

Finally, don’t forget to consider the hand of the wearer when selecting size for a diamond in a ring.

Wider fingers can make a diamond look smaller than it would appear if put on a hand with slimmer fingers.

Also, consider the fact that more elongated diamond shapes make the fingers look longer, while wider shapes accentuate the width of the hand.
