What does "eye clean" mean when describing a gemstone?

"Eye clean" refers to a gemstone that does not have any inclusions or imperfections visible to the unaided eye. This term is significant within the gemstone industry because it indicates a certain level of clarity that enhances the stone's overall appearance and value. When a gemstone is described as eye clean, it means that even upon close inspection without magnification, the viewer will not discern any internal flaws or inclusions, which allows the stone's color and brilliance to be the focal point.

This characteristic adds to the appeal of the gemstone for both jewelers and consumers alike, as visibility of inclusions can detract from the beauty and perceived quality of the stone. It is important to note that "eye clean" does not imply that the gemstone is flawless; rather, it simply means that any imperfections present are so minor or well-hidden that they cannot be seen without the aid of magnification. In contrast, terms like flawless or those denoting visible inclusions under magnification represent different clarity grades that may not meet the standards set by the "eye clean" designation.
