Hi! I get lost looking at all the stats and desperately need help picking labs for earrings. I would like each diamond to be in the 1.75 - 2.0 carat range or 3.5- 4.0 ctw. Looking for brightness (D, E, F, G, H). Willing to spend up to $1,000-$1500. Looking at Ritani? Any suggestions are greatly appreciated!!!!! Many thanks!
