But remember that pearls aren't crystals - they're a mullusk's organic reaction to an irritant in its shell, so it makes more shell to coat the irritant. Mollusks live in the water, so a water element would be logical. They often live in shallow, muddy flats. So Seaweed or Mud would be logical dragons, but I don't think that both would be the choice. I think Mud/Storm because a storm might stir up grains of sand that would get into a shell and become the seed for the pearl.
