Hello, I recently purchased an 1.01c i VVS2 from Ritani and it was delivered today. I immediately took it to Shane Co. where my setting was being held to have it set. When I got there the woman asked me if I was sure about my diamond purchase and asked me to look at some of their i colored diamonds. They were all better. Not one had a tint of yellow to them, and side-by-side with mine, mine looks really yellow. Mine is GIA certified, and the inscription matched the cert. Shane Co. however does not use a lab except their own, therefore not certified. What could the problem be here? I left it there to be set, but I'm kind of getting worried. Should I have it reappraised locally? Thank you in advance to anyone that can shed some light on this situation. Have a good day.
