It is simple. When Zelena's life force left her body, her magic was set free from the pendant and joined with her then she trveled through time and so on.

The pendant counted as a 1up, an extra life on a video game, pretty much saved her from dying once and then releases the magic and then becomes useless. IT's like a one time use sort of thing....unless she puts it back on. She's more powerful with it supposedly, but I doubt that, but I doubt that matters since she was more powerful than Regina before she had the pendant.
