No, but the fact that her body lost its magic seemed to suggest that either the soul gem lost all of its magic, or that the soul gem was removed from the body (no longer exists), since it goes down the Witch's belly if we assume it to be eaten.

And this episode, we saw that a Soul Gem without a body can't do anything. It just freezes in time. If she does somehow come back, it won't be from her effort alone.
