So I was doing some thinking about the pearls, which led me to the question of what pearls represent in general. So hear is what I found:
Pearls symbolize wisdom acquired through experience. In the Roman Empire they stood for wealth and prosperity. They are often associated with the moon, and have been described as the tears of gods. They are connected to chines dragons as well. If this interests you, I got most of this info here.
Side note- My birthday is in June, and the birthstone for June is the pearl. This always kinda annoyed me, because pearls are not actually stones, though they are considered gems.
