I have seen lab grown diamond being quite a bit cheaper than mined ones for a while now. As in ×2 to ×3 times cheaper even.
And yes, funnily it seems that the purer a diamond is (clear, few impurities etc) the higher its price/carat, until it is so pure that it means it is a lab grown diamond and not a natural one and the price drops
