I purchased two lab created diamonds from Ritani for them to set as a pair of earring studs. I received IGI certifications with the earrings showing both were D VVS2, which is what I ordered and what I paid for. I had the earrings appraised, as I do for all my jewelry, by a local jeweler who I have done business with for 30 years and who has been in business for over 50 years. I found out that the diamonds were instead a color of G/H. I am surprised, and very disappointed, that Ritani didn't immediately see that these were not color D diamonds before setting them and shipping them to me as color D. The difference between a color D and G/H should be immediately obvious to a jeweler. It was certainly obvious to my eye. Yet they set and sold stones that were visibly not even close to what what represented.
