The eyes won't come off. They are inserted into the head. The gem itself is on a post. If you look inside the head you will see two bulges where the eyes are. that is what the post is set into. If you do want to remove them you need to slice away the plastic and should be able to pop em out with pliers. I have a TE Quackers head with one eye. If you like I can pop her head in some water later and see what happens to it.
