Some lab-grown diamonds are blue in appearance. This is called the blue nuance, shown in the image above. Some lab diamonds even have a greenish tint, rather than a blue one. The blue nuance occurs in diamonds that are grown through the HPHT high pressure high temperature process. Luckily, not all HPHT diamonds have it.
During the HPHT process, lab diamonds are sometimes exposed to boron, which speeds up the diamond growth process. Boron impurities are what cause the diamond to turn blue. Natural fancy blue diamonds get their color from boron being present while they are formed, too. You may be wondering what the difference is between fancy blue diamonds and diamonds with a blue nuance since they both are blue in appearance. Both diamonds with a blue nuance and fancy blue diamonds are classified as type IIb diamonds.
These extremely rare diamonds are semiconductive, meaning they can conduct electricity, and contain boron impurities. Fancy blue diamonds, on the other hand, have more saturated color and are graded differently as they are not colorless diamonds. Boron is a culprit in diamonds with fluorescence , as well as diamonds with a blue nuance. However, fluorescence is not the same as the blue nuance.
Fluorescence is when a diamond glows a certain color under UV light. For most diamonds with fluorescence, they glow blue under UV light, however, they can also glow yellow, green, orange, red, or white.
Diamonds with a blue nuance will appear blue no matter what type of lighting they are in. Most shoppers seek a diamond that appears colorless and will shy away from diamonds with a blue nuance.
However, if you think stones with a blue nuance are alluring, why not go for one? A diamond with a blueish tint will make for a unique engagement ring. Sometimes, HPHT diamonds will not read as a real diamond with a diamond tester, even though they are real diamonds. You can learn more about testing lab-grown diamonds here.

Our algorithm can identify blue hue in an automated way to help speed up the search process for a nice lab diamond.
The first step in the image processing pipeline is to remove the background. Edge detection algorithms can be used to create a mask to separate the foreground from the background. Our background contours are not perfect, but they are good enough for our purpose of evaluating diamond body color. The next step is to transform the image into the HSL color space.
With a way to identify blue pixels, we can now score the blueness of each image. The score distribution for the F color grade is exactly what you hope to see when constructing a classifier. F color is the last color grade where the blue hue score distribution is distinct.
Color hue is less differentiated with D and E as expected because D and E are at the top of the color scale.

This presence of boron is responsible for the blue nuance of a diamond. They are not, but there are similarities. Both blue diamonds and blue nuance diamonds belong to type IIb. Type IIb diamonds are extremely rare and have boron impurities in their atomic level. Also, both these diamonds are conductive.
Blue nuance diamonds have a faint blue tint whereas blue diamonds have a saturated blue color. Even though blue nuance diamonds have a bluish tint, they are graded using normal color grades.
The color grade varies from grade D to Z. Blue diamonds are graded just like any other colored diamonds are graded. Color grades of colored diamonds are faint, very light, light, fancy light, fancy, fancy intense, fancy vivid, and fancy deep. Even though fluorescence and blue nuance can have traces of boron, both are different. The diamonds with fluorescence properties glow when illuminated with a UV light.
Red, orange, green, and yellow glow are also possible. Diamonds with fluorescence can also contain traces of aluminum or nitrogen elements. Most diamond buyers prefer colorless diamonds hence they avoid diamonds with blue nuance. HPHT-developed diamonds with boron can cause issues with diamond testers, even though they are real diamonds.
A diamond with a blue hue can be unique and if you find the looks pleasing, go for it. As the HPHT-grown stones increase in popularity, the retailers sometimes get diamonds with a blue hue. Blue Nuance is the faint amount of blue tint that the diamond may display. While it is rare in mined diamonds, it sometimes can be seen in the HPHT-grown ones. Boron is used during the HPHT method as the catalyst for growth and the means of removing the nitrogen from the chemical makeup of the diamond.
Just like with the yellow or brown tint, the blue hue affects the color grade of the diamond in the report. Stones with the bluish undertone usually get lower color grade than colorless and near colorless gemstones. Thus, they are usually priced significantly lower than white gems. Because of that there is a misconception among the trade that the blue tint is somehow worse than other undertones.
And while blue nuance diamonds do stand out by comparison from the brownish or yellowish ones, it is often not in a worse way.
