cloud | ˈklau̇d
A group of tiny white inclusions in a diamond
The term “cloud” refers to a mass of crystals and/or pinpoints that are found too close to one another within the diamond itself. On condition on the nature of the cloud inclusion, it may oftentimes cause an issue in the overall appearance of the diamond. For instance, if the clouds become too large, it may give rise to a white color and foggy materialization, which in turn, influences the diamond's light transmission properties. Another way you can determine if there’s a cloud inclusion in the diamond is if you notice a circle encompassed with tiny red dots or pinpoints on its diamond grading report. On the other hand, if the clouds are small and dispersed throughout the diamond, it in the general run of things, doesn’t cause any issues. On top of that, if the diamond weighs above one carat, the GIA report will certainly include a diagram which clarifies the details of the diamond.
