The Rarity and Value of Fancy Color Lab Grown Diamonds

Lab-grown diamonds have gained significant popularity in recent years due to their ethical and sustainable nature, as well as their remarkable beauty. Within this category, fancy color lab-grown diamonds stand out for their exceptional rarity and unique allure. In this article, we will explore the factors that determine the rarity and value of these captivating gemstones, shedding light on their fascinating characteristics and the reasons behind their increasing demand.

The Science Behind Fancy Color Diamonds

To understand the rarity and value of fancy color lab-grown diamonds, it is essential to grasp the science behind their mesmerizing hues. Natural fancy color diamonds are created by the presence of certain impurities or structural defects within the crystal lattice during their formation deep within the earth over millions of years. Similarly, lab-grown fancy color diamonds are developed through a controlled process that replicates the conditions under which natural diamonds are created, resulting in stunning colored stones.

Factors Influencing Rarity and Value

While natural fancy color diamonds are renowned for their exclusivity and hefty price tags, lab-grown alternatives possess their own unique characteristics that determine their rarity and value. Here are five prominent factors that play a pivotal role in assessing the worth of fancy color lab-grown diamonds:

1. Color

The color of a diamond is perhaps the most crucial aspect determining its rarity and value. Fancy color lab-grown diamonds possess a remarkable array of hues, ranging from stunning blues and vivid pinks to intense yellows and vibrant greens. The rarity of certain colors varies, with blue, pink, and green being relatively uncommon in nature. Lab-grown diamonds, on the other hand, offer a more extensive color range since they can be created with specific impurities or modifications to the growth process. As a result, lab-grown fancy color diamonds give consumers more options to choose from, catering to individual preferences and expanding the overall market.

2. Intensity

The intensity level of the color displayed in a fancy color diamond also greatly influences its rarity and value. Within each color range, there is a spectrum that ranges from faint to deep saturation. The more intense and saturated the color, the rarer and more valuable the diamond becomes. This is true for both natural and lab-grown fancy color diamonds. However, lab-grown diamonds have an advantage in this aspect as they can be engineered to exhibit a higher intensity of color, achieving vibrant and deeply saturated hues that are extremely rare in natural diamonds.

3. Size

Size is a crucial factor in determining the value of any diamond, including fancy color lab-grown diamonds. Larger stones are inherently rarer than smaller ones, regardless of their color or intensity. However, it is essential to note that an increase in size does not necessarily equate to a proportional increase in value. The rarity of a specific color and intensity combination must also be taken into account. Therefore, a smaller, intensely colored fancy color lab-grown diamond may have a higher value than a larger, but less intense stone.

4. Clarity

The clarity of a diamond refers to the presence of internal or external flaws, known as inclusions and blemishes, respectively. Although clarity does not have a direct impact on the color of fancy color diamonds, it is still an important factor in assessing their overall quality and value. The presence of inclusions or blemishes can affect the diamond's durability and, subsequently, its desirability. Lab-grown diamonds, whether fancy color or not, tend to have fewer inclusions compared to their natural counterparts, leading to higher clarity grades and subsequently increasing their value.

5. Market Demand

The final factor influencing the rarity and value of fancy color lab-grown diamonds is market demand. As with any luxury product, the laws of supply and demand greatly impact pricing. While lab-grown diamonds have gained immense popularity in recent years, fancy color lab-grown diamonds have garnered particularly significant attention due to their unique beauty and ethical appeal. As consumers become increasingly aware of the environmental and social benefits offered by lab-grown diamonds, the demand for these remarkable gemstones continues to rise. The combination of limited supply and growing demand has resulted in an increase in the value and desirability of fancy color lab-grown diamonds.


In conclusion, the rarity and value of fancy color lab-grown diamonds are determined by various factors such as color, intensity, size, clarity, and market demand. These captivating gemstones offer a wide range of colors that are meticulously crafted through a controlled process, providing an extensive selection for consumers. Lab-grown diamonds have redefined the jewelry industry by offering an ethical and sustainable alternative to natural diamonds, while still embodying the stunning beauty and allure that have captivated mankind for centuries. As technology continues to advance, it is expected that the rarity and value of fancy color lab-grown diamonds will continue to evolve, solidifying their place as exceptional and sought-after treasures in the world of luxury gemstones.
