If I were to use a pearl instead of a bullet in an old fashioned flint-lock pistol or a musket, could it survive? What would it do on impact? Would it be too light for an effective ammunition?
Basically, what would be its properties as ammunition?
EDIT: I did not consider the world to be a major concern, since it has nothing to do with the question.
My world is in the early stages of discovering the "New world". People made a special boat in an attempt to discover a new continent, but they found countless numbers of small islands forming a large crescent formation at the bottom of this formation is a island that is full of pearls. I wondered if I could have the people from southern islands carry a round pearl with them as a reminder of their homeland and for good luck and to remind them that they should not be controlled by greed and as an emergency ammo.
So I wanted to know if it would be possible to use a pearl as ammunition. Because shooting that pearl would be a sign that you are not controlled by greed and many wear the damaged pearls as a proof. But I don't know if the pearl would survive the impact.
Southeners consider the explorers as invaders. They have more developed firearms than the people from the continent, so they consider guns as standard weapons, while the continent knows only about ship cannons. On the islands there are temples made from rare materials, that form a prison for a demon of greed. If they get torn down it will be released. (that is the only magic in this story.)
As you can see the world has nothing to add to my question.
