Lab Diamond Color Chart: Find The Hidden Gems

Diving into the world of diamonds, you embark on a fascinating journey of discovery and enchantment. One of the key aspects that shape a diamond’s beauty, value, and character is its color. Here, the diamond color chart comes into play, providing a fundamental compass to navigate the mesmerizing maze of these precious stones.

The Gemological Institute of America (GIA), a globally respected authority in diamond grading, introduced the diamond color chart and scale to establish a standardized means of evaluating and discussing diamond colors. 

The ‘D’ at the beginning of the scale represents diamonds that are absolutely colorless, the rarest and, dearly sought after. 

As the diamond color moves down the alphabet from “D” to “Z” the tint becomes more noticeable, the price of the diamond decreases. This is due to the higher demand for colorless or near-colorless diamonds in the market.

By harnessing cutting-edge technology, manufacturers of lab-grown diamonds have achieved a feat once considered impossible – crafting diamonds that perfectly rival the color and quality of their mined counterparts. This innovation has made the previously prohibitive premium colors attainable, creating a whole new world of possibilities.

In this article, we will delve deep into the world of lab-grown diamond color, exploring the fascinating processes behind their creation, and how these shimmering stones are changing the face of the diamond industry. Prepare to uncover how you can now own the diamond of your dreams without breaking the bank. So sit back, read on, and let us take you on an enlightening journey into the radiant realm of lab-grown diamonds.

Key takeaways

1. Diamond color refers to the presence or absence of a yellow or brown tint in the stone. The Gemological Institute of America (GIA) created a standardized diamond color scale ranging from D (colorless) to Z (light yellow or brown). Even a slight yellow tint can lower a diamond’s value.
2. Diamond color influences the stone’s beauty, perceived size, value, and price. Colorless diamonds reflect more light, enhancing their sparkle, brilliance and fire.
3. Color Grades: D, E, and F diamonds are colorless, G to J are near colorless, and K to L are faintly colored.
4. Beyond Z grade, diamonds are considered ‘fancy color’ and are graded on hue, tone, and saturation. These fancy colored diamonds can be expensive due to their unique colors and rarity.
5. Balancing the 4Cs: The four aspects that define a diamond’s quality are Carat weight, Cut, Color, and Clarity. Each factor should be balanced to ensure your diamond has optimal fire, brilliance and sparkle.
6. Proper independent diamond grading certificates are really important.
7. Lab grown diamond colors are identical to mined diamond colors.

What is Diamond Color?

Diamond color is one of the first things we notice about a diamond and plays a vital role in its overall appearance and allure. When it comes to diamonds, color is not about the rainbow hues we typically associate with the word, but rather, the absence of color. 

The hue and intensity of a diamonds color is created by the presence of trace elements like nitrogen (yellow and brown hues) and boron (blue hues).

In the diamond world, the best color is no color at all, which allows the stone to act like a prism, dispersing light into a beautiful spectrum of shades. 

However, the importance of color extends beyond mere aesthetics—it also significantly impacts the value and price of the diamond, making it a key consideration in any diamond purchase.

Color is one of the C’s in the very useful of the “4C’s of diamonds“-model.

GIA’s International Diamond Color Scale

In an effort to standardise diamond color grading, the reputable Gemmological Institute of America created a diamond color scale that serves as a yardstick in determining a diamond’s color. This scale grades diamonds from D (completely colorless) to Z (light yellow or brown).

This color scale is a globally recognized benchmark and utilized by all diamond grading laboratories. It helps ensure that no matter where you are in the world, when you talk about a diamond’s color grade, everyone is on the same page. Think of it like a universal language that diamond enthusiasts, jewelers, and gemologists speak, making it easier for you to understand and select the perfect diamond.

How Diamonds are Graded for Color

Diamond color grading is a meticulous process performed under controlled conditions by expert gemmologists.

Individual loose diamonds are compared to master stones of established color under controlled lighting and specific viewing conditions to identify which diamond color grade it most closely matches.

The grading process involves multiple gemologists to ensure accurate and consistent grading. It’s worth noting that while the process is meticulous, color grades can be very close to one another and the difference between two adjacent color grades can be challenging to perceive, especially to an untrained eye.

The Importance of Diamond Color

The color, or lack thereof, in a diamond greatly impact a diamond’s visual appeal. For traditional white diamonds, a high color grade, which signifies less color, enhances the stone’s brilliance and sparkle. A truly colorless diamond (D grade) will allow light to pass through it more easily, resulting in more sparkle and shine.

Color can subtly influence our perception of a diamond’s size. Diamonds with less color can appear slightly larger to the naked eye than those with more color. This is because diamonds that are lower on the color scale absorb more light, which can make the diamond appear smaller.

Diamond color has a direct impact on a diamond’s price and value. In white diamonds, those that are colorless are the rarest, thus commanding higher prices. As you move down the color scale, the presence of yellow or brown tints can decrease a diamond’s value.

On the other hand, fancy color diamonds, like blues, pinks, and yellows, are treasured for their unique and vivid hues, which give each stone a distinct personality and charm.

Diamond Color Chart

To make diamond color grading more understandable, the GIA developed the diamond color chart. The chart represents the color grades visually, making it easier for diamond shoppers to understand their diamond’s color grade.

Colorless Diamonds (D-F)

D, E, and F color diamonds fall into the colorless range. Their absence of color allows them to reflect more light, enhancing their sparkle and making them highly sought after in engagement rings.

In the world of mined diamonds this color range has been prohibitively expensive, and common sense often steered buyers away from paying the premiums for this range. 

Since it takes the same time to create a high color diamond than something lower on the scale – labs have focussed on creating colorless diamonds. 

This color range is awe-inspiring, and usually the tie-breaker when someone is between an average color mined diamond or a top-tier color lab grown diamond. 

D – Absolutely Colorless: This is the highest grade on the GIA color grading scale. D color diamonds are extremely rare and exhibit virtually no color. They allow the most light to pass through, resulting in exceptional sparkle.

E – Colorless: Diamonds in this category only have minuscule color traces that can only be detected by expert gemologists. They’re also highly prized and are indistinguishable from D color diamonds to the untrained eye.

F – Colorless: F color diamonds have a nearly undetectable amount of color that can only be identified by gemological experts under specific conditions. To the naked eye, they appear colorless.

You cant go wrong in the colorless range. 

Near Colorless Diamonds (G-J)

Diamonds with a G-J color grade are considered near colorless. These diamonds may have a very slight yellow or brown tint, but it’s usually difficult to see unless compared side-by-side with a completely colorless diamond.

These do sell at a slight discount to the colorless lab diamond prices, but usually the price difference is small enough that couples opt for the colorless range.

G – Near Colorless: Though technically in the “near colorless” category, G color diamonds mostly appear colorless and offer excellent value. Any hint color is hard to detect unless compared side-by-side with diamonds of a higher grade.

G is the lowest color grade offered by Lumen Diamonds. 

H – Near Colorless: An H color diamond has a very slight warmth to it, but it’s rarely noticeable unless compared directly to diamonds of a higher color grade. They are an excellent value, offering a near colorless appearance at a less premium price.

I – Near Colorless: Diamonds of an I color grade have a slightly detectable warmth or tone, especially when compared to diamonds of higher color grades. Still, in most cases, these diamonds appear colorless when viewed face up.

J – Near Colorless: J color diamonds exhibit a warm tone that can be more noticeable in larger diamonds or when set in white metal settings. Despite this, they are still considered good value, and the color isn’t usually detectable to the untrained eye.

Faint Color Diamonds (K-L) 

The K-L grade diamonds have a faint, yet observable light brown or yellow tone to them.

In the mined diamond variety, these colors have traditionally been quite popular with those optimising for diamond size without blatant detrimental compromise on color. 

They were white enough to pass as white-ish once set in a piece of jewelry. 

Once the price barrier was somewhat removed to higher color lab grown diamonds, demand in this range is very close to zero. 

How Diamond Color Affects Price

Diamond color is one of the four Cs (Carat, Clarity, Cut, and Color) that significantly influence the price of a diamond. Diamonds at the top end of the color scale, classified as colorless (grades D-F), are exceptionally rare in nature, which inherently drives up their price.

As the diamond’s color grade improves, moving closer to the ‘colorless’ end of the spectrum, its price tends to rise, irrespective of whether it’s a natural or lab-grown diamond. This is because the absence of color allows a diamond to best exhibit its other desirable qualities, like brilliance and sparkle.

Conversely, as you descend down the diamond color scale from D-Z, the visible presence of color increases and the price typically decreases. This is due to the fact that most consumers prefer diamonds that appear white or colorless.

Lab-grown diamonds, however, offer a slight departure from this rule. Because the creation process is controlled, producers often invest their resources into creating diamonds with top color grades. This often results in lab-grown diamonds of superior color quality being more readily available and affordable than their natural counterparts.

 Nonetheless, color remains a crucial factor in determining a diamond’s value, making it an essential aspect to consider when purchasing a diamond.

Fancy Colored Diamonds – Off the Chart

Fancy color diamonds, the official term for diamonds that display vibrant hues, present a unique and thrilling departure from traditional white diamonds. While most diamonds are prized for their absence of color, fancy color diamonds do a 180 and are celebrated for their intense and rich hues of every color of the rainbow.

Vivid, crisp colors are not commonly found in nature and, as such, these diamonds often command high prices and are in significant demand. The rarity and exceptional appeal of these diamonds often see them sold at prestigious auctions to discerning collectors.

Unlike their D-Z sisters, these have actually proven to appreciate over time. 

The intensity of the color is one of the main factors that determine the value of a fancy color diamond. Generally, the more intense and pure the color, the higher the diamond’s cost. This is particularly true for rare colors such as red, which have been known to fetch over a million dollars at auction.

While natural fancy color diamonds remain rare and highly prized, advancements in lab technology have made these colorful marvels more accessible. Exotic colors like red, pink and blue are now available for little more than ther colorless sisters. 

Mesmerising fancy color lab diamonds, created under controlled conditions to produce beautiful, saturated hues, are now available at a fraction of the price of their natural counterparts.

Balancing Diamond Color with the Other 4Cs

For a diamond to look great its carat, color, clarity and cut grade (4C’s) should be in perfect harmony. 

Here’s the balancing act to get the most diamond for your money. 

Set your budget

You do you. There’s no wrong or right here.

Balancing color with cut – the most important C

A diamond’s Cut grade refers to how well a diamond was cut and polished from uncut/rough to maximise its characteristic life, sparkle and brilliance.

To optimise this light show – the ideal angles, dimensions, and proportions of every facet have been scientifically determined, and diamonds are compared to that blueprint during grading.

If the diamond has been poorly made the size, clarity and color don’t matter… You’re stuck with what looks like a dull piece of glass.

The cut grade should be Excellent or Ideal. 

Non-negotiable.

Balancing color with clarity

Clarity refers to a diamond’s internal and external imperfections, known as inclusions and blemishes. Diamonds with fewer inclusions are more valuable. However, similar to color, minor clarity flaws may not be visible to the naked eye, especially if the diamond is well-cut.

As long as a diamond appears free from visible inclusion to the naked eye – that’s good enough. No one is going to inspect your engagement ring under a microscope.

Above eye-clean grades you’re paying for parameters that have no visual impact on your ring. 

VS1 and VS2 is the goldilocks-zone for diamonds under 3,00ct. 

The grand finale: Color vs Carat. 

Finding the right balance between color and carat was once a formidable challenge!

Enter lab diamonds, the game-changers that considerably cooled the competition.

When it comes to lab diamonds, paying a premium for colorless stones (D – G) is not only justifiable but also quite reasonable.

However, a word of caution: avoid the temptation of going too far down the color scale. The goal is not to see how low you can go but to find the sweet spot in color.

Here comes the exciting part!

After finessing the cut, clarity, and color, it’s time to focus on size. Given our carefully calibrated parameters, you can now scale up your diamond’s carat until it aligns with your budget’s ceiling.

Navigating this path will lead you to a diamond that’s not only beautiful and high quality but also tailored to your budget. Your perfect diamond awaits!

Does Diamond Shape Impact Diamond Color?

Diamond shape can significantly impact the perception of its color.

Round brilliant cut diamonds are known for their exceptional light reflection. This brilliance can amplify the brightness of the diamond, often making it appear more colorless than other diamond shapes.

Contrarily, step-cut shapes, such as the emerald or asscher cuts, have more expansive, open facets. These larger facets can accentuate the diamond’s color, making any color grade more noticeable. If your aim is to emphasize the diamond color, the cushion cut could be an ideal choice due to its unique ability to highlight the hue.

As a general guideline, selecting diamonds with an H color grade or higher can typically ensure that the gem predominantly exhibits a white appearance regardless of the diamond shape. This holds true regardless of the setting or the color of metal used in the jewelry piece.

The forgiving nature of round diamonds is particularly evident when set in rose or yellow gold settings. Any faint color present, even in diamonds graded I and J on the color scale, can be camouflaged, enhancing the overall beauty of the diamond jewelry.

Impact of Fluorescence on Diamond Color

Fluorescence refers to a diamond’s tendency to emit a soft, colored glow when subjected to ultraviolet light. 

Strong blue fluorescence can increase the perceived color of a lower shade diamond (J, K,L…) by a grade or two in daylight. Just ensure the fluorescence is blue – it’ll be marked on the certificate.

In rare cases, strong fluorescence can make a diamond appear hazy or oily.

*All diamonds offered by Lumen have been double-checked and guaranteed to be free from any negative effects of fluorescence.
