My boyfriend and I put down a deposit on an EGL diamond that are getting and when I called the jeweler to ask if I could get it independently appraised, he said that it was unnecessary because he had already done an appraisal on the stone and sent it to me. the appraisal from them matched the EGL cert, but didn''t give me any extra info other than color, clarity, cut dimensions, and approximate value (which was about 1 1/2 times the price i paid for it. is this normal and acceptable for the jeweler who sells you the diamond to do the appraisal as well?
