I got engaged a month ago. My honey did not get a certification with the diamond. We got an appraisal for insurance purposes (GIA certified gemologist). Says the stone is 1.79, H color VS2. I just happened to stop by a local "Jewlery Exchange" for something else, and a jeweler told me my ring is I color at best (he just looked at at on my finger. Should I be worried by what the jeweler said or trust the GIA appraiser guy? Should I get this stone certified on top of the appraisal? Any bit of advice would help. Thanks!!
