How do I compare the diamond ratings

[sudhir_shukla]

Hi,

I''ve been looking at diamonds which have been certified from various institutes like GIA, AGS and EGL. How do I find out what a rating from EGL maps onto with GIA and AGS and like wise. Is there some kind of chart I can use that available for this purpose.

You help is greatly appreciated

Thanks,

Sudhir
