If you aren't happy with the earrings, I'd say this is the time to exchange them. I know even "freshadama" doesn't mean "perfect," so if the divot was towards the back and not seen when wearing, I may not bother, if it was me. But if it shows or just bugs you, why not get a different pair.
P.S. I can't wait to see the pics!
