Hi everyone, just a quick question for those who are into diamonds! I can't really tell diamonds apart - to me they're either white or shiny or not so white or shiny but I don't know if they're D, E, F or IF, S2, I2....are these things that are only obvious to the jeweler? Or is this something that a person can pick up? If someone is wearing an I2 diamond, are those inclusions visible to a person just looking at it? This is where all these questions are leading up to...suppose a buy diamonds from Macy's or a similar boutique, what kind of rating do you think they are? I mean I understand that they're not top of the line since it's a department store, but they're not bottom of the heap either right? Generally under the lights they are shiny, but should I bother getting one, or should I buy one from a jeweler? Thanks for your time!
