BLACK DIAMOND QUALITY: THE 4C’S OF BLACK DIAMONDS
You’ve probably heard of the 4Cs of diamonds: color, clarity, cut, and carat. The 4Cs are quality gradings that can tell you much about the quality of a diamond. However, the standard 4Cs are tailored to white diamonds and black diamonds aren’t graded by the same parameters. So how do you evaluate the color, clarity, cut, and carat weight of black diamonds? Read on to learn how the 4Cs of black diamonds differ from the 4Cs of white diamonds.
COLOR
Fine natural black diamonds can range in color. The most highly prized natural black diamonds are the ones that are completely opaque, which means no light passes through the stone. However, such natural black diamonds are extraordinarily rare, hard to find, and extremely expensive. So nearly all the black diamonds sold in jewelry are a natural black diamond stone that receives a high temperature treatment to enhance the depth of the natural color, in order to give it that ideal color.
While deep, evenly colored black diamonds are considered the best type of black diamonds, there is technically no ideal color grade for black diamonds. This is because black falls outside the GIA's standard color grading scale, and black diamonds are therefore not traditionally graded. So when you select a black diamond, there is no ideal color grade for you to hunt for. Instead, to ensure your diamonds have a deep and even black color, we recommend looking for black diamonds that have been heat treated to improve their color.
CLARITY
Diamond clarity is still important for black diamonds. However, black diamonds are naturally heavily included, simply due to how they’re formed in the earth, so you will not find black diamonds with flawless clarity. When you search for black diamonds, you should primarily be concerned with whether or not they have inclusions on or near their surface, which would look like a cut or a crack to the naked eye. Diamondstuds.com only carries high quality black diamonds to ensure that no inclusions will visibly appear 'open' on the table of the diamond.
CUT
Diamond cut is one area in which black and white diamonds are graded similarly. As with white diamonds, the cut of black diamonds is important. Jewelers and gemologists recommend selecting a black diamond that is well cut, as this will ensure it has a high luster and well proportioned facets that refract maximum light.
CARAT WEIGHT
Carat weight is an objective weight measurement, so white diamond and black diamond carat weight is graded the same way.
But when you browse black diamonds, you’ll find that they’re much more affordable than white diamonds of the same carat weight. The affordable price of black diamonds allows more people to go up in carat weight and get larger, more bold black diamonds. Black diamond studs are most popular in 1 carat and larger due to their value.
MM Size of Each Round Stud by Carat Weight
| TOTAL CARAT WEIGHT EARRING PAIR | CARAT WEIGHT PER EACH SINGLE STUD | AVERAGE MM SIZE EACH ROUND |
|---|---|---|
| 0.25 ctw | 0.13 | 3.2MM |
| 0.33 ctw | 0.18 | 3.6MM |
| 0.50 ctw | 0.25 | 4.1MM |
| 0.75 ctw | 0.38 | 4.6MM |
| 1.00 ctw | 0.50 | 5.2MM |
| 1.50 ctw | 0.75 | 6MM |
| 2.00 ctw | 1.00 | 6.5MM |
| 2.50 ctw | 1.25 | 7MM |
| 3.00 ctw | 1.50 | 7.4MM |
| 4.00 ctw | 2.00 | 8.2MM |
BLACK DIAMOND STYLE: STYLE GUIDE
Now that you understand black diamond quality, let’s talk about black diamond style. Why do people gravitate toward black diamonds? What are your style options for black diamond studs and other black diamond jewelry? Read on to learn the answers to these questions and more.
What is the draw to these dazzling dark gems?
Black diamonds have a unique and distinctive dramatic color that is captivating. Perhaps they are best adorned by the person who likes to 'stand out from the crowd' and keep a one-of-a-kind style.
Like the white diamond, they remain one of the hardest substances known. Even in their color enhanced state, they remain of high strength and great value.

BLACK DIAMOND STUD SHAPES
Like white diamonds, black diamonds come in many different shapes. The two most popular shapes for black diamond studs are round and princess cut diamonds. Round black diamonds provide an elegant and romantic look, while princess cut black diamonds provide a bold modern style. As you deliberate between these two shapes, consider which shape’s style would most closely fit your personal style.

BLACK DIAMOND STUD SETTINGS
Black diamond studs come in numerous different setting styles. Which setting style is right for you? Learn more about your setting options by browsing our descriptions of common black diamond stud settings below.

4-Prong Basket Settings
Four prong basket settings are perhaps the most classic type of solitaire earring setting. This style of setting holds your center diamond in place in a delicate basket with four slim prongs. If you want black diamond studs with a touch of traditional style, 4-prong basket settings are an excellent option.

3-Prong Martini Settings
Three prong martini earring settings are similar to 4-prong basket settings, yet this solitaire stud earring setting style has a different silhouette. This earring setting has a rounded triangular basket that narrows into the earring’s post, which looks much like a martini glass when viewed from the side. This setting is a delicate, elegant variation on the classic prong earring setting.

Bezel Settings
Bezel settings are known for their sleek, modern style. This type of stud setting holds your center stone in place with a smooth ring of metal. This smooth metal setting provides a contemporary look and also provides excellent protection for your gemstones. The continuous ring of a bezel setting is highly secure and provides an extra level of protection from bumps or drops.

Halo Settings
Halo settings are perfect for those who love a bit of glamour. In a halo setting, your center stone is enclosed in a ring of glimmering white diamonds. Halo settings are a stunning and dramatic choice for black diamond stud earrings. The bright white brilliance of this setting style’s white diamond accents beautifully contrasts with the rich depth of black diamonds.

PRECIOUS METALS
Black diamond studs look beautiful with many precious metal types. Cool toned metals (like white gold, platinum, sterling sliver, and stainless steel) tend to add a sleek, modern look to black diamond studs. While warm toned precious metals (like yellow gold or rose gold) can soften the look of black diamonds, giving black diamond jewelry a more romantic or classic look.
So which precious metal is right for your round or princess cut black diamond stud earrings? Let’s take a closer look at all your cool and warm toned precious metal options.

Cool-Toned Precious Metals
Among cool-toned metals, you have both precious and non-precious options for your jewelry. Generally, we recommend selecting precious metals (like white gold and platinum) over non-precious metals (like stainless steel or sterling silver) for black diamond jewelry. White gold and platinum have more natural luster when compared to non-precious white metals, which better complements the luxe look of black diamonds.
Your two white precious metal options for black diamond studs are white gold and platinum. These two precious metals look very similar, but one may be better for you than the other. If you have any metal allergies, platinum would generally be the best white precious metal for you, as it’s hypoallergenic. On the other hand, if you don’t have any metal allergies, you may prefer 14k white gold or 18k white gold, as white gold of any karat is less expensive than platinum. 14k white gold in particular is a great option for those on a budget (or for those who would prefer to put more of their budget toward their center stones), as it is a bit less expensive than 18k white gold.

Warm-Toned Precious Metals
If you prefer the look of warm-toned precious metals with black diamonds, you have two options: yellow gold and rose gold. Yellow gold has a bright warmth that adds a classic or traditional look to black diamond studs. Rose gold has a rich pink gold tone that adds a touch of romance to black diamond studs.
Among both yellow gold and rose gold, you have the option of either 14k or 18k gold. Generally, 14k gold will be slightly less expensive than 18k gold, due to its lower pure gold content. However, 14k and 18k gold also look slightly different, so you may want to select your gold karat based on how it looks. 14k yellow gold is slightly lighter in color than 18k yellow gold, which has a richer golden color. 14k rose gold looks a bit more pink than 18k rose gold, since it contains a higher amount of copper (which is what gives rose gold its blushing hue).
There’s no better option between 14k and 18k gold, only the option you prefer more. At DiamondStuds.com, our diamond studs are customizable, which allows you to choose the gold karat that best fits your budget and personal style.
EARRING BACKS
Earring backs can affect how comfortable and secure you feel when wearing your studs. At DiamondStuds, we allow you to choose your ideal earring back when you buy any pair of our customizable black diamond studs. Choose from the most popular, secure classic push backs or screw backs to create your perfect pair of black diamond studs.

Frequently Asked Questions
The 4 C’s refer to the four main factors used to evaluate the quality of a diamond:
- Carat Weight: The size of the diamond, measured in carats.
- Cut: How well the diamond is cut, affecting its brilliance and sparkle.
- Color: The absence of color in a diamond, with a scale ranging from D (colorless) to Z (light yellow or brown).
- Clarity: The presence of internal or external flaws (inclusions and blemishes), rated on a scale from Flawless to Included.
The creation of lab grown diamonds replicates the process of natural diamonds in an environment of extreme heat, pressure, and carbon. The main difference lies in time and origin: while natural diamonds develop deep within the Earth’s mantle over billions of years, lab grown diamonds are formed through cutting-edge technology in just a matter of weeks.
Lab grown diamonds, also known as lab created or man-made diamonds, are real diamonds cultivated in advanced laboratory settings under highly controlled conditions. They possess the same physical, chemical, and optical characteristics as natural, earth-mined diamonds, including the identical carbon crystal structure that gives them remarkable brilliance and durability.
Visually, Lab Grown Diamonds are exactly the same with the same hardness level and durability as Natural Diamonds. These gems both have the same refractive qualities, chemical composition and strength.
Our lab grown diamonds display the same physical, chemical, and optical characteristics as natural diamonds, and exhibit the same sparkle, fire and scintillation. Thus, making them an ideal choice for those looking for a budget friendly alternative to natural diamonds.
Neither natural nor lab-grown diamonds are universally better. Both are real diamonds with the same chemical composition, crystal structure, brilliance, and sparkle. The best choice ultimately depends on your personal preferences, budget, and what matters most to you.
Diamonds and other gemstones are measured in metric carats, with one carat equaling 0.2 grams, approximately the weight of a paperclip. It's important not to mix up carat with karat, which denotes gold purity, such as "18K gold." Like how a dollar breaks down into 100 pennies, a carat is divided into 100 points. For instance, a 50-point diamond weighs 0.50 carats. However, two diamonds of the same weight can vary significantly in value due to factors like clarity, color, and cut, known as the Four C’s. Most diamonds used in fine jewelry are one carat or less in weight. Precision is crucial because even a small fraction of a carat can greatly affect cost.
Carat weight refers to the weight of an individual diamond, while Total Carat Weight (CTW) refers to the combined weight of all diamonds in a piece of jewelry.
For example, when shopping for diamond stud earrings:
- 1.00 Carat Total Weight (CTW): Each earring contains approximately a 0.50-carat diamond, for a combined total of 1.00 carat.
- 2.00 Carat Total Weight (CTW): Each earring contains approximately a 1.00-carat diamond, for a combined total of 2.00 carats.
- 3.00 Carat Total Weight (CTW): Each earring contains approximately a 1.50-carat diamond, for a combined total of 3.00 carats.
The Cut of a diamond is often confused with shape and is a term sometimes used interchangeably. But when referring to a Cut of a diamond it is a grade that determines the quality of proportions and arrangement of facets that produce attractive diamonds in relation to light. So, the better the cut, the better the sparkle. Shape simply put is the overall outline of the stone, such as round, heart, pear and oval.
The shape is the visual aspect of the diamond such as Oval, Pear, Emerald, Heart, etc.
The setting refers to only the finding or mounting that holds the diamond. Examples include: 4-Prong Basket, 3-Prong Martini, Bezel, etc.
Fluorescence actually is the absence of a blue tone in diamonds. None would be the best grading available for Fluorescence.
Not all diamonds are graded by a laboratory such as GIA, IGI, EGL, etc. Non-certified diamonds are graded based on the same criteria as certified diamonds (the 4 C’s), but the grading is done internally by the jeweler or retailer rather than by an independent third-party organization. This can result in less consistency and reliability in the grading. Be sure to shop our certified section if you only want a pair of certified diamonds.
A GIA diamond grading report is an independent evaluation issued by the Gemological Institute of America (GIA), one of the world's most respected gemological organizations. It provides an assessment of a diamond's characteristics, including its Cut, Color, Clarity, and Carat Weight, helping buyers understand the diamond's quality and identity. A GIA report provides confidence and transparency when purchasing a natural diamond.
GIA (Gemological Institute of America) and IGI (International Gemological Institute) are two widely recognized diamond grading organizations. Other laboratories may also provide diamond grading reports, but their grading standards, methodologies, and industry recognition can vary.
