I'm in the market for princess diamond earrings. I was talking to a wholesaler, and he told me a few things that I wouldn't mind some feedback on. Here they are:1. You don't need GIA (or other) certification for earrings - it's not worth it and he hasn't sold a pair in 20 years2. Quality is not nearly important in earrings as it is in a ring.3. 1.0 karats on each ear is huge, and will look funny on a fairly petite woman.Any thoughts?Thanks
