I just got this ring in the mail and it is beautiful. It is not too large (comparable in size to a 2 ct. real diamond depending on the table/cut). It is also not set too high for the size of the center stone. I compared it to my 1.47 ct. real diamond and it is a smidge larger. The only thing is, this ring is much cleaner and without flaws, very brilliant. My diamond is nearly colorless at an F, but, this ring's center stone is truly colorless. My diamond also has a slight inclusion underneath one of the 6 pronges, this ring is flawless...super clean...plus my platinum has lost it's polish over the years whereas this ring is brand spankin' new. So, all in all, you could tell it is fake if you examined it from like 6 inches. But, under inside light, or an intimate setting, there is no way to tell this is not the real deal. Can't speak for in the daylight because I haven't checked yet. You can't beat the price, grab it.
