by Scc1515 » Aug 23, 2018 Hey everyone, I just purchased a diamond for an engagement ring but now I am questioning my selection. The diamond is rated as a VS1 however, there is a knot in it. I have looked over it a ton in pictures and 360 view and I can't seem to see it anywhere. My biggest worry is that this will affect the durability of the diamond long term. Luckily it is from Blue Nile and it has not shipped yet so I can change or exchange it if needed. Below is a link. Any input on if this inclusion is something I should be worried out would be greatly appreciated. https://www.bluenile.com/build-your-own-ring/diamond-details/LD10428934 Thanks for the help!
