Yellow Lab Grown Diamond a Radiant Gem
Yellow diamonds, known for their vibrant hues, are a popular choice in the colored diamond market. Their unique color results from the presence of nitrogen during formation, making them a captivating option for retailers looking to diversify their gemstone offerings
Yellow Diamond
Yellow diamonds have emerged as a captivating and increasingly popular choice among colored diamonds, enchanting jewelry enthusiasts across the globe with their warm, sunny hues. Their popularity has grown significantly in recent years, with yellow diamonds now accounting for approximately 60% of the colored diamond market. These exquisite gems range from pale, subtle yellows to intense, vivid canary shades, offering a spectrum of options for discerning collectors and fashion-forward individuals alike.
The allure of yellow diamonds lies not only in their unique color but also in their versatility and symbolism. Often associated with happiness, joy, and optimism, yellow diamonds have become a favorite for engagement rings, statement pieces, and high-end fashion jewelry.
What Are Yellow Lab Grown Diamonds?
Yellow lab diamonds are man made diamonds created in laboratory settings that exhibit a yellow color. These diamonds are produced using advanced technological processes, primarily CVD (Chemical Vapor Deposition) and HPHT (High Pressure High Temperature). Lab grown yellow diamonds offer a more affordable and sustainable alternative to natural yellow diamonds while maintaining the same physical and chemical properties.
Types of Yellow Lab Diamonds
Yellow lab diamonds come in various shades, and each of these shades has different variations:
- Canary yellow diamond
Canary yellow lab grown diamonds offer the same intense, vivid yellow color that closely resembles the bright plumage of a canary bird, but at a more accessible price point. These lab-created gems are highly sought after in the jewelry world for their striking appearance and exceptional color saturation, rivaling their natural counterparts.
- Light yellow shades
Light yellow lab grown diamonds offer a subtle and elegant option for those seeking a hint of color in their jewelry. These diamonds exhibit pale yellow tones that provide a delicate warmth to their appearance. Typically graded as “Fancy Light” yellow. The softer hue of light yellow diamonds makes them versatile for various jewelry designs, from engagement rings to everyday wear.
- Dark deep yellow shades
Dark deep yellow diamonds showcase a rich, saturated yellow color that can sometimes appear to have slight orange or brownish undertones. These diamonds are often graded as “Fancy Deep” or “Fancy Dark” yellow. Their intense hue makes them popular choices for statement jewelry pieces, offering a bold and luxurious appearance.
How are yellow lab diamonds made?
Colored lab-grown diamonds are initially created using the same methods as white diamonds, primarily through Chemical Vapor Deposition (CVD) or High Pressure High Temperature (HPHT) processes. However, to achieve specific colors, additional treatments are required:
- LPHT Process: The Low Pressure High Temperature (LPHT) process is often repeated on the diamonds to enhance or modify their color. This involves subjecting the diamonds to high temperatures (but lower pressures than HPHT) for extended periods, which can alter their atomic structure and introduce color centers.
- Color Centers: Different colors are achieved by creating specific defects or “color centers” in the diamond’s crystal structure. For yellow diamonds, nitrogen atoms are introduced, while for blue diamonds, boron is used.
- Irradiation: Some colored diamonds, particularly pink and red, are created through irradiation followed by annealing (controlled heating and cooling). This process creates vacancy defects in the diamond’s structure, which, when combined with nitrogen atoms, can produce pink or red hues.
Types of fancy yellow color lab diamonds
Yellow diamonds come in various types of shades of colors available. These can be identified with an adjective such as vivid, intense, dark shade, light shade, and deep color to describe their color, or a letter grade such as D or IF, with the latter being the highest quality since it has no noticeable inclusions. The Gemological Institute of America (GIA) grades all gemstones and assigns each a grade based on these categories: Fancy Light, Fancy Dark, Fancy Deep, Fancy Intense, and Fancy Vivid.
Fancy Light Yellow
Light shades are the most common types of yellow diamonds, making up about 70% of all yellow diamonds. Light shades are graded between G and J, with a J being one of the highest grades for this type. Since these grades range from very light to almost colorless, they can be confused with white diamonds. However, a closer look at the diamond’s features (such as distinctness and depth) will help you tell them apart.
Fancy Dark Yellow
Fancy Dark yellow diamonds are diamonds with strong yellow characteristics, ranging from H through K in terms of color grading. To determine the diamond’s tone, it is still better to use the features of the diamond instead of its color.
Fancy Deep Yellow
Deep-yellow gems are graded J through N in terms of color. However, like their lighter counterparts, their appearance greatly depends on other characteristics such as light and darkness as well as brilliance and depth.
Fancy Intense Yellow
Today, there is a trend to create more intense yellows. This makes the bright orange to yellow-orange stones more popular. They have a higher level of saturation, so the bluish tone is very apparent. Their high color intensity also makes them desirable in fashion jewelry, and they are often found with some clarity and/or cut characteristics to make them look even brighter.
Fancy Vivid Yellow
Fancy Vivid yellow diamonds have intense, very saturated yellows with a distinctive bluish hue. They are more difficult to distinguish from the red shades of red diamonds since they look completely similar to white diamonds. However, you can judge them more easily with help from other features. The color saturation is so high that it makes them hard to compare to other types of yellow diamonds since they can be mistaken for their red counterparts if given equal lighting conditions.
How are Fancy Color Lab Diamonds Graded?
Colored lab diamond grades were measured with the same 4cs as just normal diamond grades measured – cuts, color, clarity, and carats included. In colored lab-grown diamonds, there is only a difference in color grade other prospects are the same. There are D to Z grades given to normal diamonds including how much tint it has but in colored diamonds like this yellow lab diamond that is scaled with Z grade.
Fancy Colored Lab-Grown Scale
- Faint
- Very Light
- Light
- Fancy Light
- Fancy
- Fancy Intense
- Fancy Vivid, Fancy Deep, Or Fancy Dark
If you are comparing the grading system between a natural diamond and lab-created diamonds there are the same grading happens. You can buy lab diamonds colored with IGI certification.
Different ways to use fancy yellow color diamonds
The fancy yellow-colored diamonds with more intense saturation are often combined with white diamonds, colorless diamonds, and light-colored diamonds for a unique look. They are also perfect for extreme fashion jewelry, especially stud earrings, which look very exotic and trendy. The combination of these precious stones with yellow gold makes a unique combination that will stand out in any successful fashion jewelry.

Price of yellow-colored diamonds
Natural diamonds are costlier and lab diamonds are 30% cheaper than real ones but fancy color natural diamonds are rare and the cost is much higher compared to lab-grown colored diamonds. Lab-grown diamonds are made in 4 weeks and on the other side, natural diamonds take billions of years to get foam. There is a lab-grown diamond with a deep, canary yellow color-based diamond more in demand rather than lighter shades, and prices go fluctuate based on demand and supply.
