i am looking for a small diamond pendant and i like the setting from bluenile much more than the whiteflash setting. but i'm not sure about the quality of bluenile ideal cut. i've bought from whiteflash before and their diamonds are very sparkly which is what i'm looking for. also for the similiar size stone in either the bluenile ideal cut or the whiteflash aca cut.....there is about a $300 to $500 price differential. does it indicate a less sparkly stone? or a premium profit?
