Hansel and Gretel in Samanthaland - S8-E10
Continuity mistake: In 1-7 The Witches Are Out, Bertha (later Hagatha) is talking to Mary, and they say that Hansel and Gretel are 2 naughty children who go around eating the nice witch's house. In this episode, the witch is a "traditional" bad witch.
Answer: The original diamond and white gold heart necklace was given to Elizabeth Montgomery by her then real-life husband, William Asher, who also directed the show. She wore it in nearly every early episode. When the necklace was lost or stolen about mid-way through the series, Montgomery had two replicas made from rhinestones. She wore either one of those for the rest of the show's run.
