What is the difference between GIA and GSI?
The industry generally expects GSI to grade diamond color one or two grades higher than the GIA. So if GSI designates a diamond’s color as G, the GIA may give it an H or I. To the naked eye, those distinctions are hard to tell apart, but sellers will charge a higher price if it’s given a G color instead of an H or I.
Is EGL as good as GIA?
The difference between EGL and GIA is that EGL is inconsistent and loose in its diamond grading, while GIA is consistent and reliable. When comparing EGL to GIA, GIA has higher standards and is more uniform in how they grade.
