So the stones you are getting can be g to i in color vvs2 to vs2 in clarity grades as per GIA standards but as IGI standards those are as mentioned in the listing. Every person can have a different opinion about the color clarity of the stone. I am not sure how practical it is to use $75000 (3 Carat E VS!) Natural Diamond stone standard for the same color clarity grade (3 Carat EVS1) Lab Grown Stone which you are getting for $750. My advice to you is whatever authenticity says please please get the stone if you do not like then I will accept the return without any question in the next 30 days of purchase. I don't want you to miss the great opportunity to buy those beautiful lab grown stones which are 100% the same chemical other properties wise as natural Diamonds at 1% of price compared to Natural Diamond.
