The engagement ring that Everett gives Nic symbolizes her success and the fact that she has made it in a world that she feels represents her true potential. When it is taken from her, it means that this world has been taken away from her, which it has been as Annaleise is the person who takes it and her actions cause Nic to have to stay in Cooley Ridge. The fact that Nic never finds it means that this world is lost for her forever.
