First off, thanks to everyone for such an educational and beneficial site! I just purchased a diamond and looking at it from the side there is a line about 2/3 down. Looking at previous topics, it sounds like this is just a girdle reflection and is normal. Is this the case and do all diamonds have this? Is this a flaw in the diamond? I''m just a little nervous because this is the first diamond I have ever purchased! Any feedback is greatly appreciated! Thanks for the help!
