how does tiffany certificate compare to gia and egl
i have compared prices of a few GIA & EGL diamonds with the same cuts and gradings, but find that GIA certified diamonds were a few hundred more than those diamonds that are EGL certified ....eport Abuse. GIA is thought to be a better certification than, EGL. With EGL make sure it says EGL-USA. EGL outside of the US is not good. Grading diamonds is an opinion and people are under the impression GIA is a stricter grader than EGL, and IGI.
