Character mistake: Samantha calls Darrin's mother "Mother Stephens" throughout episode. In most episodes, she is "Mrs. Stephens." I can't find any other episode where she is "Mother Stephens".
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.
