Revealing mistake: When Samantha starts trashing the private detective's apartment, she causes a chandelier to fall onto a coffee table, breaking the table. However, it is easy to see that the table breaks just before the chandelier falls on it. (00:20:10)
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.
