[Clarity Grade] SI2 [Description] 
Slightly Included (2ndDegree) – SI2 clarity inclusions are seen clearly and obviously with the help of a jeweler’s loupe. With step cuts like Emerald and Asscher cuts, an SI2 clarity inclusion will most likely be visible to the naked eye (as is the case with the diamond in the sample photo on the right). With other brilliant shapes (basically all the other common shapes), an SI2 clarity inclusion will usually be clean to the naked eye.As with the SI1 sample photo above, I specifically chose a concentrated black center inclusion to illustrate just how bad an SI2 can get. A center black SI2 on an Emerald Cut is about as bad as an SI2 as there is. As I mentioned above regarding an SI1, in most cases, the SI2 clarity grade is made up of several (or many) smaller inclusions. In these cases, since the SI2 is spread out all over the stone, and not concentrated in any one area, the diamond is usually eye clean.
