Hello,
I'm new to the site and to the quality of diamond's. If a diamond is GIA certified and one is IGI certificate. When a IGI appraiser appraise a diamond can he tell if its a real diamond? Please Help
I'm sorry I'm not understanding all your concerns. Can you I ask that you re-state and give a little more detail? Then we would be able to help you better.
Not all appraisers are the same, but most can tell a diamond from a non-diamond given the right tools.
