our jeweler who we have purchased from many times has quoted us a $30,000 sapphire. the stone is gorgeous to look at, stunning color, a cushion cut, 6-7 carats. we looked at it under his microscope and noticed an inclusion that he said was "not a problem" and that is normal, that shows him it has not been heat treated or altered in anyway, etc..... should we be skeptical? if we are paying this much, should the stone have NO inclusions or are inclusions part of having any sapphire and the important thing is the color as he has said....
