So I have a local jeweler that I frequent. I''ve been looking around for diamond earrings for awhile (waiting for the tax return). She can get a good price on a SI pair, but it wouldn''t have a certificate. It would only come with a stamped appraisal. Sounds too risky huh? But we have been going to her for awhile now, and she would have alot to lose if she was putting out bad stones. HELP!
