I have a local jeweler by my house that I have currently found a diamond that I like. The diamond has no certs but they classify it as a I-clarity and I-color with out certs how can they make this call. I asked to get it GIA certified and they said they usually don''t cert there diamonds it''s just a piece of paper and is not traceable to the diamond. They also said that GIA and EGL are the same. After reading various sites I see a lot of people prefer GIA is there a difference? Also, they are charging me $300 to get this GIA done. Is this standard rate? Also, do a lot of jewelers handle things like this by not having certs?
