What Is Carat Weight?
A metric “carat” is defined as 200 milligrams. A professional may describe the diamond’s weight below one carat by its ‘points’ alone since each carat is generally subdivided into 100 ‘points’, allowing extremely precise measurements.
For example, a jeweler may refer to a 0.25-carat diamond as a ‘25 pointer.’ Diamond weights that exceed one carat are expressed in carats and decimals; for instance, a 1.07-carat diamond would be referred to as ‘one point seven carats.’
If every other aspect of the diamond is equal, the price of a diamond increases with carat weight as bigger gems are generally rarer and thus far more sought after.
But, two diamonds that have the same carat weight can have entirely different values based on other diamond characteristics, including color, clarity, and cut.
That being said, it’s also crucial to keep in mind that the value of a diamond is determined by assessing all of the 4Cs, not only the carat weight.
In addition, many people confuse the terms carat with karat. While carat is used to describe the weight of the gemstone, Karat is a unit of measure for the fineness of gold. It is abbreviated as “K” or “Kt.”
How Is Carat Weight Measured?
Diamond weight is generally measured using an electronic micro-balance scale. To ensure maximum precision, professionals in the diamond grading lab weigh diamonds to the fifth decimal place.
On the other hand, in the trade, a diamond’s carat weight is typically stated in two decimal places.
Using stricter rules than general mathematical rounding, labs usually round up the weight of a diamond only when the last digit in the fifth decimal place is a 9. For instance, a stone that weighs 1.148 carats would be rounded down to 1.14, whereas one that weighs 1.149 carats would be rounded up to 1.15.
So, due to the fact that a diamond’s price is calculated by multiplying the stone’s carat weight by the price per carat, you would want to ensure that the diamond you intend on purchasing has been precisely weighed.
Also, you want to ensure the diamond’s stated carat weight is provided with two decimal points. Why? A 0.98-carat stone isn’t equal to a 1.00-carat diamond, and its price should reflect the carat difference, given that both stones have the same color, clarity, and cut grades.
Don’t Confuse Diamond Carat With Diamond Size
Regarding the carat weight same as the size seems like common sense, but it doesn’t always work. Different gemstones have different densities, so two stones that have identical carat weights may differ in size.
For instance, rubies have a greater density than diamonds, so a 1-carat ruby will usually look smaller compared to a 1-carat diamond.
Furthermore, the way a stone is cut also impacts its perceived size. For example, a poorly cut round brilliant diamond may have a way too thick girdle – extra carat weight can be hidden below the diamond’s girdle.
Once this type of gem is set in a ring, you won’t be able to see this “hidden” carat weight. Therefore, a poorly cut 1.25-carat diamond may look the same in size as a well-cut 1.0-carat diamond, meaning you’ll end up paying more for the additional carat weight with no added benefit.
This is where the diamond’s cut grade becomes crucial – more than its carat weight.
The takeaway: avoid using carat weight alone in order to determine a diamond’s size. If it’s a round brilliant cut diamond, look at the cut grade of the stone provided on the diamond grading report, to ensure it’s well-cut, so you won’t have to pay extra for the wasted carat weight.
Factors That Influence Diamond’s Price
When a 100-carat diamond is found – which is extremely rare – it makes news in the diamond trade. The rarer the stone is, the more valuable it becomes. The thing is, most natural diamonds are smaller than a carat, so, this is reflected in the price.
Due to their rarity, larger diamonds dictate a premium – so much so that the price difference is exponential. In other words, a 1.00-carat diamond will cost much more per carat than a 0.25-carat diamond. Furthermore, a 2.00-carat diamond will have a higher price per carat than a 1.00-carat diamond, and so on.
So the question is, how much does a 0.25-carat diamond cost?
A 0.25-carat diamond is generally worth between $275 to $440. Apart from the diamond’s carat weight, other elements play a role in determining a diamond’s worth. When it comes to assessing a diamond’s value, the following factors are taken into consideration:
- Diamond’s cut
- Diamond’s clarity
- Diamond’s color
- Diamond certification
Diamond Cut
Diamonds are cut to maximize the brilliance, fire, sparkle, and overall visual beaut. The diamond’s cut is actually a measure of light performance as light hits the stone.
Before diamonds are cut and polished, they’re excavated in a form known as a rough diamond. The rough diamond’s outer layer is opaque and difficult to see through. These rough stones have very little to no sparkle at all. This is due to the fact that they lack facets that serve to reflect light.
Diamond’s brilliance and sparkle are a result of light performance. As light rays hit a diamond, they penetrate the stone, bounce around and reflect within the gem, and in the end, return to the viewer’s eyes.
Cutting a diamond directly affects the volume of light performance achieved. The shapes, angles, sizes, and locations of the diamond’s facets will dictate how much a diamond will sparkle.
Once a diamond has been processed, its cut can be graded. For example, GIA grades a diamond’s cut by precisely measuring the sizes and angles of the diamond’s facets. These include:
- Table
- Depth
- Girdle
- Pavilion
- Crown
- Culet
In addition, polish and symmetry can also play a small role in determining the cut grade of the diamond.
Each diamond size and shape has an ideal cut proportion. So, if you’re looking to purchase perfectly cut stone, simply ask one of the diamond professionals, and they can point out several options that feature ideal proportions.
Pricing Effect
Like the other features of a diamond, the diamond’s cut grade can have a huge impact on pricing. The diamond manufacturing technology has seen enormous improvement over the past several years, allowing proportions to be more precise in cutting practices.
With round brilliant cut diamonds, an Excellent cut grade can have a between 5% and 10% premium over the next cut grade, which is a Very Good grade. The same goes for Very Good to Good.
Fancy-shaped diamonds don’t have GIA assigned cut grades. The reason for this is that, with fancy shapes, diamonds can have all kinds of shapes, widths, and lengths, all the while maximizing the sparkle of the stone.
Selecting Cut Grade
The cut is generally considered the most important factor when selecting a diamond to buy. Excellent cut diamonds are the best ones obviously but the most expensive ones.
Very Good cut diamonds, on the other hand, offer more value. The differences in brilliance are pretty subtle, although they can be detected when compared side by side.
We would always recommend maximizing the diamond’s cut grade, if possible.
Fancy-shaped diamonds have fewer restrictions since beauty is in the eye of the beholder. Nevertheless, you can safely go one grade lower with fancy diamond shapes. However, ideally cut fancy-shaped diamonds are pretty rare.
Ultimately, it’s your choice, and you must remember that other factors impact a diamond’s beauty and price. Be sure to select which factors and attributes matter most to you.
Diamond Color
Both natural and lab-grown diamonds are available in many colors. The traditional colorless stones in most engagement rings are white diamonds. On the other hand, fancy colored diamonds feature vivid shades such as pink, yellow and green.
Color is a natural element in diamonds. As the gems are formed deep beneath the earth’s surface over millions of years, trace elements can lead to diamonds having a yellowish or brownish tint. It’s more common for diamonds to have some tinting — which varies in tone and saturation — than to be completely colorless.
The color of a diamond is graded by assessing the stone’s body color face down on a pure white background. Diamond experts compare the gem to master stones with grade color shading. If the stone possesses more yellow tinting than one but less than the other, it will receive a grade in that range.
The GIA has standardized a color grading scale that rates diamonds from D to Z – D being the highest color grade and Z being the lowest. When it comes to grading, diamond color is determined by the lack of color in a stone. The less color a stone possesses, the higher the grade.
Colorless diamonds generally sparkle more than those with a yellowish or brownish tint since the color subtly distracts the eye from seeing sparkle.
So, which diamond color is best for my 0.25-carat diamond? That depends on what you’re looking for:
Diamond Color D-F: Colorless – stones in this range have few traces of color – professional gemologists can only detect that. These diamonds typically need to be compared to lower or higher graded stones to identify the color accurately. Less than 1% of all gem-quality diamonds fall in this color range.
Diamond Color G-J: Near Colorless – these gems possess a very little color that can be identified by trained eyes. The G/H color diamonds are generally most popular since they balance lack of color and value.
Even though minor sparkle distractions can be noticed in I/J colors, these stones still sparkle brilliantly and have good value. This color range represents the top 15% of all gem-quality diamonds.
Diamond Color K-M: Faint – diamonds with these color grades tend to have faint yellow or brown tinges. The color impacts the gemstone’s sparkle by slightly dulling it. When inspected, the color may be recognized in jewelry; however, there are ways to reduce this. These stones represent the top 40% of all gem-quality diamonds.
Diamond Clarity
Since natural diamonds result from carbon exposure to extreme conditions of high heat and pressure deep below the Earth’s crust, this process can lead to the creation of a variety of internal flaws known as ‘inclusions’ as well as the external ones called ‘blemishes.’
Assessing the clarity of a diamond involves determining the number, size, nature, and location of blemishes and inclusions and how these influence the diamond’s overall appearance.
If you are trying to decide what clarity grade is the best for your 0.25-carat diamond, remember that no diamond is perfectly pure – the closer it comes to purity, the better its clarity grade is.
The GIA diamond clarity scale is divided into six categories, some of which are further divided, making a total of 11 specific clarity grades:
- Flawless (FL) – No inclusions and blemishes are visible under 10x magnification.
- Internally Flawless (IF) – No inclusions are visible under 10x magnification.
- Very, Very Slightly Included (VVS1 and VVS2) – These stones have slight Inclusions but they are difficult to see under 10x magnification even for a skilled grader.
- Very Slightly Included (VS1 and VS2) – These diamonds have inclusions that can be detected with effort under 10x magnification, although they can be characterized as minor.
- Slightly Included (SI1 and SI2) – Inclusions can be noticed under 10x magnification in these stones.
- Included (I1, I2, and I3) – Diamonds with these clarity grades feature inclusions that are obvious under 10x magnification which may impact both transparency and brilliance.
Many internal and external flaws are too tiny to be detected by anyone other than a professional gemologist. A VS1 and an SI2 graded diamond may look identical o the naked eye, but these stones are quite different regarding overall quality.
This is why an accurate evaluation of diamond clarity done by an expert is crucial. Knowing what diamond clarity truly means can help you better understand the elements that impact the diamond’s quality and price.
The clarity differences are bigger than the color differences as the scale is smaller; thus, differences in diamond prices can be pretty significant between clarity grades. Obviously, the highest clarity grade is much rarer, so the price jumps are large.
Since inclusions are usually microscopic, it becomes rarer to find IF of FL stones, hence the exponential price increase.
Price differences can range from 15% to 25% between clarity grades, while the differences within the same clarity category can range from 5% to 15%. As we already mentioned, no two stones are the same. Therefore, no two diamonds with the same clarity grade are the same.
Since a subjective range sets a diamond’s clarity grade, the size, number, location, and type of imperfection can affect the stone’s price.
For example, an SI1 graded diamond with an eye-visible black crystal under the table’s center will be considerably less expensive than a diamond with the same clarity grade but with an eye-clean feather on its corner than a prong can cover.
Diamond Certification
While the differences in previously mentioned diamond characteristics can be minor, the price differences aren’t. Since a high expertise level is required for diamond assessment, it’s important to know your stone’s precise characteristics and attributes.
Given that pricing varies quite a bit, you’d never want to buy a diamond with certain quality advertised but receive something completely different. This is where diamond certificates come into play. These certificates standardize diamond characteristics so you know exactly what you’re getting for the money you’ve paid for. Simply put, it’s protection for consumers globally.
Many diamond shoppers wonder why it is that some gems are accompanied with certificates, charts, or extensive packets of information upon purchase, whereas others only come with a receipt.
While you can request any diamond-related information before purchasing a stone and get copies of information on one you choose, the more in-depth certificates and grading reports are reserved for gems that have received official certification.
Gemological institutions that carefully and precisely evaluate, compare, and grade gems for quality and consumer demand, provide certificates for these stones. Non-certified diamonds may come with ratings or accompanying documentation, but they haven’t gotten any official certificate from a diamond grading lab, such as the GIA.
Do you need diamond certification for your 0.25-carat diamond?
Well, the most obvious advantage of purchasing a certified diamond is the insurance that you’re getting what you pay for, and that it’s of paramount quality and beauty.
On the other hand, the greatest disadvantage to purchasing a diamond that comes with a certificate is the price tag most of them carry. You’re bound to pay extra for gems worthy of certification, but still, it’s worth every cent to the discerning consumer.
