I think a lot depends on the dresses of the bridesmaids. Do you know the color and neckline type?
Also, it's important to pick jewelry that is non allergenic. Sterling silver, gold or goldfilled are a safe bet. You don't want people braking out in rashes or ears turning green in the middle of the ceremony

For that reason, I would not choose David Aubrey.
All three of these designers have interesting pieces, but I'm not sure I would choose them for a wedding.
