i am looking at getting 2ctw diamond studs for myself i am a man. I know nothing about diamonds. Is my best best to go with the ACA series at whiteflash, if i want the best diamond possible. Some of the blue signature ideal stones are cheaper but from what i am reading you never know what you really are going to get when you order from bluenile. Also since i am man what would be the best setting to get 3 or 4 prong?
