I'm choosing between the .30 and .37 ctw for a yg DBTY and am in desperate need of help! The specs for the two seem so different that I'm not sure what would be a better pick. Online it says that the .37 is a color I, VVS2, while the .30 is a color E, VS2. I'm not sure whether color or clarity is more important with a diamond this size. I'm wondering if I should go down to a .25 to get "safer" specs (F, VVS2), or even the .29 is a G, VS1 which sounds more balanced... I wish I could go up to the .40 but I think hubby might say I'm pushing it I know next to nothing about diamonds so ANY kind of help or advice would be really appreciated!
