Welcome to our exploration of the fascinating world of diamonds, both natural and lab-grown. Though they have different origins, they share the same properties and are evaluated by the same standards - the Four Cs: Carat, Cut, Colour, and Clarity. In this guide, we'll delve into the significance of diamond colour, a vital aspect for all diamonds.
Introduction: When it comes to assessing the quality and value of a diamond, colour plays a crucial role. Alongside the other three Cs – cut, clarity, and carat weight – colour significantly influences a diamond's overall appeal and worth. While colorless diamonds have traditionally been the most sought-after, fancy coloured diamonds have gained popularity for their unique hues and rarity. In this expanded article, we will delve deeper into the importance of colour in the diamond world and explain how colours are indicated and graded.
In the diamond industry, the Gemological Institute of America (GIA) is the leading authority on diamond colour grading. The GIA developed a comprehensive and widely accepted colour grading system, which ranges from D (colorless) to Z (noticeable yellow or brown tint). The system is based on a comparison of a diamond's colour to a set of master stones under controlled lighting conditions.
For fancy coloured diamonds, the GIA uses a separate grading system that assesses the hue, tone, and saturation of the colour. Hue refers to the dominant colour, tone indicates the relative lightness or darkness of the colour, and saturation measures the intensity of the colour.
Below you can see a overview of the colours.
Several factors contribute to a diamond's colour, including its chemical composition and crystal structure. Most natural diamonds are composed of carbon atoms arranged in a cubic crystal lattice. However, the presence of trace elements or defects in the crystal structure can lead to the formation of coloured diamonds.
For example, the presence of nitrogen atoms can cause a diamond to exhibit a yellow or brown hue, while boron impurities can result in a blue colour. Exposure to natural radiation in the earth can also alter a diamond's colour, leading to green diamonds. Additionally, stress or deformation in the crystal lattice can cause the selective absorption of light, creating pink or red diamonds.
Diamond colour has a significant impact on value. In general, colorless diamonds (grades D, E, and F) command the highest prices due to their rarity and exceptional beauty. Near-colourless diamonds (grades G, H, I, and J) are slightly more common and more affordable. Diamonds with noticeable colour (grades K through Z) are less valuable, but may still be desirable for certain jewellery designs or personal preferences. Always be aware that the larger the diamond, the more visible the colour is.
Fancy coloured diamonds, on the other hand, are valued based on the rarity and intensity of their colour. Some of the most valuable fancy coloured diamonds include vivid blue, pink, and green diamonds. Other colours, such as yellow, are more common and may be more affordable, but can still be quite valuable if the colour is particularly intense or pure.
At DiamondsByMe, we offer you the flexibility to select your preferred diamond from our extensive list or opt for a standard diamond using our user-friendly configurator. For natural diamonds, you can choose from SI/G colour, VS/E colour, or VVS/D colour options, ensuring that we cater to a variety of preferences.
We categorize our diamonds as good, better, and best. In our opinion, the VS/E quality and colour strikes the perfect balance between excellent quality and competitive pricing.
For lab-grown diamonds, we provide two options: VS/G and VVS/D. Due to the smaller price difference between the various qualities of lab-grown diamonds, we decided to offer only two distinct grades - good and very good. This approach ensures that we have a suitable diamond option for every individual's budget.
At DiamondsByMe, we prioritize providing top-quality diamonds. All our diamonds from 0.30 crt up come with a certificate to ensure you get the value you deserve. Natural diamonds include a GIA or HRD certificate, while lab-grown diamonds come with an IGI certificate.
Due to the cost of certification, we only provide certificates for round diamonds of 0.30 carats or larger, as the price of the certificate would exceed the value of smaller stones. Fancy cut diamonds may require a higher carat size for certification. When selecting a diamond, you can check the details on the page to see if a certificate is provided—usually, this is the case for diamonds of 0.60 carats and above.

A diamond's colour is an essential factor in determining its overall appearance, value, and desirability, but it is important to consider it alongside the other three Cs (cut, clarity, and carat) when assessing a diamond's quality.
The cut of a diamond refers to the proportions, symmetry, and polish of the stone. It significantly impacts the diamond's brilliance, fire, and scintillation, which contribute to its overall beauty. A well-cut diamond can maximize light return and enhance the appearance of the gem, even if it has a lower colour grade.
Clarity refers to the presence of internal and external imperfections or inclusions in a diamond. Flawless diamonds are extremely rare and valuable, but most diamonds have some inclusions that may or may not be visible to the naked eye. A diamond with a higher clarity grade and a lower colour grade can still be stunning and desirable.
Carat weight is the measure of a diamond's size, with one carat equal to 200 milligrams. Larger diamonds are generally more valuable, as they are rarer than smaller ones. However, a larger diamond with a lower colour grade might show more visible colour, so the balance between size and colour is essential.
In summary, a diamond's colour is an important factor to consider, but it should be evaluated alongside the other three Cs (cut, clarity, and carat) to determine the overall quality, beauty, and value of the gemstone. Each of these factors contributes to the unique characteristics and appeal of a diamond, and the perfect balance depends on personal preferences and priorities.

Conclusion: Understanding the importance of colour in the diamond world is crucial for both industry professionals and consumers. A diamond's colour can significantly impact its value, rarity, and overall appeal.
The price of a diamond is directly influenced by its colour. In general, colorless diamonds command higher prices, while diamonds with noticeable colour may be more affordable. However, this rule doesn't apply to fancy coloured diamonds, which can be quite valuable due to their rarity and unique appeal.
Fancy cuts, such as the pear, marquise, oval, and radiant, can sometimes minimize the appearance of colour in a diamond. This is primarily due to the unique geometry and facet arrangement of these cuts, which can distribute light differently compared to traditional round brilliant cuts. The strategic placement of facets can help to mask or disperse colour, making it less noticeable, especially in diamonds with faint to light colour grades.
For fancy coloured diamonds, the impact of a fancy cut on colour visibility can vary. In some cases, the cut can enhance the hue, making it more vibrant and desirable. In other instances, it may reduce the intensity of the colour, which could potentially lower the value of the diamond. It's essential to examine each fancy coloured diamond individually to determine the effect of the cut on its appearance and value.
In summary, while colorless diamonds typically fetch higher prices, fancy coloured diamonds have their own unique appeal and rarity, which can also make them valuable. The impact of fancy cuts on colour visibility depends on the diamond's specific characteristics, and this can play a role in determining the overall price and desirability of the gemstone.

Fluorescence is a phenomenon that occurs in some diamonds when they emit visible light upon exposure to ultraviolet (UV) radiation. This happens due to the presence of trace elements, such as nitrogen or boron, or structural defects in the diamond crystal lattice. These impurities or defects can absorb energy from UV light and subsequently release it as visible light, causing the diamond to emit a glow, typically blue, but sometimes yellow, white, or even green. In the diamond industry, fluorescence is graded on a scale ranging from "None" to "Very Strong." While fluorescence can sometimes enhance the appearance of a diamond with a lower colour grade by making it appear whiter, it can also cause a slight haziness or "milky" appearance in some instances, particularly in diamonds with strong or very strong fluorescence. However, this effect is not always noticeable and may not impact the overall beauty or value of the diamond. It's essential to consider fluorescence as one of the many factors that contribute to a diamond's unique characteristics and charm.
Conclusion : So it can make the diamond more beautiful or less beautiful. At DiamondsByMe, we provide by default our diamonds with certificate in grade "N" which means (None) no fluorescence. This way, we know for sure that it will not affect the diamond.
Brown, green, and milky (BGM) diamonds are a category of natural coloured diamonds that exhibit distinct hues and features. Brown diamonds, also known as "chocolate" or "cognac" diamonds, obtain their colour from the presence of nitrogen atoms or lattice defects in their crystal structure. Green diamonds, on the other hand, acquire their colour through exposure to natural radiation in the earth's crust over millions of years. Milky diamonds get their name from their hazy or opaque appearance, which is typically caused by a high concentration of inclusions or microscopic gas bubbles within the diamond.
Pros of BGM diamonds include their unique and distinctive colours, which can add personality and individuality to a piece of jewellery. They are also often more affordable than traditional colorless diamonds, making them an attractive option for those on a budget or seeking an unconventional choice. BGM diamonds can also hold symbolic meanings, such as stability and dependability for brown diamonds, growth and renewal for green diamonds, and purity and innocence for milky diamonds.
Cons of BGM diamonds include their potential lower market value compared to more traditional diamonds, as they may not be as highly sought-after by collectors or investors. Additionally, the hazy appearance of milky diamonds might not be desirable for those who prefer a clear and brilliant diamond. Finally, the unique colours and characteristics of BGM diamonds may not suit everyone's taste or style, so it's essential to consider personal preferences when selecting a BGM diamond for a piece of jewellery. Overall, BGM diamonds offer a unique and affordable alternative to more traditional diamonds for those who appreciate their distinctive colours and characteristics.
At DiamondsByMe our diamonds with certificate are always delivered without BGM, this way you can be sure that you are getting the best of the diamond you have chosen.
Fancy coloured diamonds come in a wide range of hues, including yellow, pink, blue, green, and even red. The rarity and value of a coloured diamond depend on the intensity of its colour, its size, and the presence of secondary hues. Some of the rarest and most valuable fancy coloured diamonds are blue, pink, and green, while yellow diamonds are more common and often more affordable.
Yellow diamonds, also known as "canary diamonds," are primarily found in the Ellendale mine in Australia and the Zimmi mine in Sierra Leone. These mines are rich in nitrogen, which causes the yellow hue in diamonds. Blue diamonds, highly sought after for their stunning hue, are primarily found in the Cullinan mine in South Africa. The presence of boron in the diamond's crystal lattice imparts the blue colour. The Cullinan mine is renowned for producing some of the world's most exceptional blue diamonds.
Green diamonds are incredibly rare, with the majority of them coming from the Orapa mine in Botswana and the Argyle mine in Australia. Their colour is a result of exposure to natural radiation in the earth's crust over millions of years. Pink diamonds, highly prized for their romantic hue, are predominantly sourced from the now-closed Argyle mine in Australia, which was the world's leading source of pink diamonds. The rarity of pink diamonds has only increased since the closure of the Argyle mine in 2020, causing their prices to soar.
The growing demand for pink diamonds, coupled with their scarcity, has led to a significant increase in their value. With fewer pink diamonds entering the market and no new major sources discovered, these precious gems continue to appreciate, becoming an attractive investment option for collectors and investors alike.
In summary, the rarity, value, and specific mines associated with fancy coloured diamonds vary depending on the colour. The closure of the Argyle mine has contributed to the increasing value and rarity of pink diamonds, making them even more sought after in the world of gemstones and jewellery.
Both natural and lab-grown coloured diamonds are available on the market. While natural diamonds are formed over millions of years, lab-grown diamonds are created using advanced technology in a controlled environment. Lab-grown coloured diamonds are often more affordable and environmentally friendly, while natural coloured diamonds offer the allure of rarity and history.
Black diamonds are a unique and captivating variety of diamonds that obtain their dark, mysterious hue through the presence of a large number of inclusions, graphite, or amorphous carbon within the stone. These elements disrupt the diamond's crystal lattice, causing it to absorb light rather than refract it, which results in its characteristic black colour. Due to their composition, black diamonds almost always exhibit some impurities, which are responsible for their distinctive appearance. You can recognize these impurities by sometimes very small craters in the surface of the stone. This is not a flaw or scratch but part of a natural black diamond. Although these diamonds are considered less valuable compared to their colorless counterparts, they possess a striking beauty that sets them apart, making them an appealing choice for those seeking a one-of-a-kind gemstone with an air of strength and elegance.
Setting out on the heartfelt journey to find the perfect diamond colour for your engagement ring is a truly personal and romantic experience. As you imagine the moment when your loved one lays eyes upon the shimmering gemstone that represents your eternal love, it's essential to keep their individual style and preferences in mind.
For those who cherish the timeless elegance and classic charm of a colorless diamond, selecting a high-grade stone with minimal colour will undoubtedly win their heart. These radiant jewels exude a celestial beauty that has bewitched couples for generations, serving as a luminous symbol of the unbreakable bond shared between two souls.
The diamond's colour grade is a crucial aspect to consider, as it not only influences the gem's value but also its overall appearance.
When choosing a diamond colour for an engagement ring, take into account the setting and metal type, as these factors can impact the colour's visual perception. For instance, a near-colourless diamond might appear just as colorless when set in a yellow or rose gold band, while a colorless diamond's brilliance could be accentuated when paired with a white gold or platinum setting, therefore if you chose a colorless diamond we always recommend to set the diamond in a white setting. Generally speaking, as a consumer, you will not be able to tell the difference between a G and D colour right away. If you put two stones side by side in G and D you will see it. So it always remains, do you want perfection then choose D, do you want for example a larger diamond then choose G colour.
As you embark on this romantic adventure, let DiamondsByMe guide you in selecting the ideal diamond colour for your engagement ring. With a deep understanding of the delicate balance between personal style, colour grade, and value, we are devoted to helping you find the perfect gemstone that will gracefully symbolize your unwavering love and commitment.
