I feel like this is a foolish question but I appreciate any guidance you may offer: i’m looking to replace the 10 x 12 mm oval moissanite in my engagement ring and the seven 3.5 x 5 mm oval moissanites in my wedding band with lab diamonds of the same size. Given that diamonds are not measured in mm and vary even in the same carat size based upon specs, how would I go about doing this? Any advice is appreciated.
