There are gradations in value based on eye-cleanliness within the SI2 grade for GIA and AGS for sure. Experts here have commented that really the SI2 is a few grades smooshed into one when it comes to pricig on the market. That said, even with the eye cleanliness of this SI3, the cert means something and it was graded an SI3 and so should cost less than and SI2 by the same lab in my opinion. But I cannot find any SI3 EGL princess diamonds to compare with I am afraid.Date: 2/26/2010 7:27:40 PM

EGL USA does have a clarity category called SI3. There is just a 'ghost feather' going through part of the diamond. It is so faint that it's hard to see with the naked eye, but it is very long and visible under the microscope that's why it received the SI3 rating. I had an SI2 diamond before, and those inclusions were even more visible to the naked eye than this SI3. I guess my question is whether stones with the same exact specs can be priced differently depending on how 'severe' the inclusions are to the naked eye?
