THANK YOU FOR VISITING OUR STORE Please note that we are listing all of our stone's color clarity grade as per IGI Lab Report. IGI Lab is the 2nd most reputable trustworthy Lab after GIA. Every person can have a different opinion about the color clarity of the stone. So the stones you are getting can be e to g in color vvs2 to vs2 in clarity grades as per GIA standards but as IGI standards those are as mentioned in the listing. 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.
