Will gold vintage jewelry match my bridesmaid’s ivory shoes?

My wedding is in March, the bridesmaids dresses are tea length and sage green. I was planning on having them wear ivory peep-toe heels of their choice (they can't agree on an exact shoe). What color jewelry is acceptable for them to wear? I actually already bought them each a different gold vintage necklace to wear for their gifts.

Does gold jewelry clash with ivory shoes? My jewelry will be a pearl set.
