1.00 Carat MARQUISE Cut IGI Certified Lab Grown CVD Diamond F Color VVS2 Clarity 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 f to h in color vvs2 to vs2 in clarity grades as per GIA standards but as IGI standards those are as mentioned in the listing. 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. Terms Conditions: Kindly keep this in mind before making your purchase that we are selling our Lab grown diamonds on multiple platforms. The Diamond you receive will be exact color, clarity and cut.
