Honestly, I never imagined buying earrings would be as complicated as buying the engagement ring (that was many years ago). I think Blue Nile might be the way to go (I'm in NOVA). She doesn't like flash and prefers quality and a little subtlety if that makes sense.
OP, you should consider stopping by Dominion Jewelers as well. Right down Rt. 7 from Tysons Corner. If you want to go on a weekend you need to make an appointment. They have staff in house that can do just about anything.
