How to Buy Diamonds – Part 2: Colored Diamonds

Colored diamonds - a vast spectrum of beauty and options

When it comes to purchasing diamonds, understanding the process of buying colored diamonds can be more intricate than that of white diamonds. The reason is simple: white diamonds offer a straightforward way of comparing stones due to the stark differences between them. However, the complexities of colored diamonds arise from the various factors that need consideration. In this guide, we will shed light on how to evaluate and purchase these exquisite stones.

The most apparent distinction between white and colored diamonds lies in their appearance. It is much simpler to differentiate between white diamonds, as their lack of color makes it easier to perceive differences between stones. For example, when examining colorless diamonds, a master color kit suffices. However, the assessment of colored diamonds demands a different approach. One must consider not only the perceived color but also how the color interacts with the diamond’s facets, affecting its overall appearance. This challenge intensifies when evaluating the color type itself. While distinguishing between colors like blue and pink is straightforward due to their distinct hues, the task becomes more intricate when comparing shades like pink and brown. Our goal is to assist you in mastering the art of evaluating these stunning stones.
First and foremost, understanding the origin of a colored diamond’s color is crucial. These diamonds derive their color from trace elements, also known as “defects,” within the crystal lattice. When light passes through these diamonds, these defects refract the light, creating captivating hues. In essence, the more defects a diamond possesses, the more vibrant its color. Now that we comprehend the source of color, let’s delve into the process of evaluating colored diamonds.
The primary parameters to consider remain consistent with those of white diamonds: Color, Clarity, Cut, and Carat. It’s important to note that these elements hold even greater significance in the case of colored diamonds compared to colorless ones, influencing the price significantly. Unlike colorless diamonds, which have standardized pricing lists, colored diamonds lack such lists, making pricing more complex and variable.

Let's begin with the simpler aspect: Carat.

The carat weight of a diamond is determined by placing it on a scale. This impacts the price as larger diamonds are rarer and hence command higher prices. However, this process is not as straightforward for colored diamonds. As mentioned earlier, these diamonds derive their color from internal defects that affect light transmission. Smaller diamonds provide less space for light to interact, resulting in vivid colors. Thus, a small diamond displaying intense yellow color signifies a high nitrogen content, making it both colorful and rare.


After evaluating carat weight, the assessment of clarity follows, albeit with heightened complexity compared to colorless diamonds due to their inherent lack of transparency. To properly evaluate clarity, one must meticulously inspect the diamond under appropriate lighting conditions and from various angles. This involves a comprehensive 360-degree examination from both the top and sides. This thorough inspection is necessary to identify any clarity imperfections that might have gone unnoticed.


Moving on to the evaluation of cut, it is advisable to separate this assessment from clarity since colored diamonds often feature additional facets intended to enhance color reflection. While colored diamonds have more facets to achieve this effect, they should not be judged too harshly. Instead, focus on key aspects such as depth and face alignment, ensuring that the color is optimally showcased on the diamond’s surface.

Lastly, we arrive at the most critical aspect: COLOR!

In colored diamonds, the evaluation involves assessing the intensity of color as well as identifying the specific color type, such as pink, blue, green, yellow, orange, etc. Sometimes, diamonds exhibit a combination of colors. The Gemological Institute of America (GIA) grades colored diamonds on a scale ranging from Faint to Dark, making direct comparisons challenging. To achieve greater accuracy, consider creating your own color tester kit. For instance, if you intend to purchase a yellow diamond, bring along a GIA-certified Fancy Yellow diamond for comparison. This will help you assess both color intensity and potential overtones

To summarize,

The most pivotal factor when evaluating colored diamonds is their color quality. Following this, clarity becomes the next crucial consideration, with larger diamonds commanding higher prices within the same quality range. Lastly, the cut ensures that the diamond appears aesthetically pleasing from a top-down perspective.
Although this may seem overwhelming initially, rest assured that mastery comes with time. In the interim, focus on certified diamonds, preferably those with GIA certification, and compare stones visually. Don’t hesitate to ask questions during your buying journey. Remember, seeking information comes at no cost and can only enhance your understanding.
