Diamonds that belong to a group called type IIb tend to appear blue. However, after absorbing high-energy light, type IIb diamonds glow in the dark for a while. This brightness varies in color from blue to pink and deep red, depending on the diamond. Fluorescence in diamonds is the brightness that can be seen when the diamond is under ultraviolet (UV) light (that is, you will see 30% of diamonds shine under ultraviolet light).
When exposed to ultraviolet light, there will be a diamond that will shine in different colors. The GIA rates diamond fluorescence as None, Weak, Medium, Strong and Very Strong. Diamonds that belong to a group called type IIB tend to appear blue. However, after absorbing high-energy light, such as UV light, type IIB diamonds glow in the dark for a short period of time.
This residual glow refers to the phosphorescence of a diamond that varies in color from blue to pink and fiery red, depending on the diamond. Fluorescence is the phenomenon of a material that glows when exposed to certain wavelengths of ultraviolet light. This is very common in natural diamonds. When diamond contains specific chemical impurities, it is likely to shine when subjected to ultraviolet light.
When comparing diamonds to each other, you will definitely see a difference between a diamond with a strong fluorescence and one with little or no. Fluorescence in diamonds is the brightness that can be seen when the diamond is under ultraviolet (UV) light (i. So, if you're wondering why some diamonds shine under UV light, think about how UV light makes your whites look whiter and your blacklight posters shine. It is also important to note that this extreme level of haze for a fluorescent diamond is also not typical and is not as common as you might think when talking about diamonds that are H or below.
If, of course, you buy a diamond in person and not online, then the best thing for you is to specifically order a diamond with a strong blue fluorescence. Since neither artificial diamonds nor the gray faux colored diamond shone at the reddish wavelength, this characteristic of natural diamonds can also help solve one of the biggest problems in the diamond market: identifying fake gems with an authentic look. The problem with some buyers is that they judge whether a diamond is fake or real based on how it shines in different light conditions. But after observing the afterglow of the world's largest deep blue diamond, experts discovered a unique method to select synthetic diamonds from natural gems and help identify stolen diamonds.
To learn more about these brilliant phosphorescent gems, chemical engineers at the Gemological Institute of America studied the Aurora Heart Collection, which contains 239 colored diamonds and a series of type IIB blue stones, in addition to the Smithsonian's Esperanza diamond and its blue heart diamond. Because each and every diamond is different, scientists realized that they could use the color of the glow and how quickly the shine fades as a type of fingerprint to identify individual gems. Brightness is thought to be an interaction between ultraviolet light, boron found in blue diamonds, and nitrogen in stones. After being exposed to this light, each of the Type IIB natural diamonds shone for several seconds.
In general terms, diamond fluorescence is blue, but from time to time, a diamond is seen to fluoresce another color, such as yellow.
