G Color SI2 diamond plot

This G color SI2 diamond clearly shows multiple dark crystal inclusions clustered near the center of the table. These inclusions appear as stark black spots and are highly visible without magnification. On the clarity plot beside the photo, they are represented by red circles, indicating that they are internal inclusions. Dark crystals like these are most often composed of graphite or uncrystallized carbon, remnants from the diamond’s formation deep in the Earth.

Because of their deep color and contrast against the diamond’s brilliance, they are among the most distracting and visually severe types of inclusions. When located in high-visibility areas such as under the table, they can significantly impact both appearance and value, even in diamonds with grades like SI2, which are popular for offering budget-friendly options when the inclusions are well hidden.

Diamonds with VS2 clarity or higher may still have crystal inclusions, but these are often small, faint, and harmless. In these cases, the inclusions are usually invisible to the naked eye and do not compromise the stone’s strength or appearance.
