10. Endora’s Brooch
The actress who played Endora, Samantha’s mother, was Agnes Moorehead. Although Moorehead was in no way a supporting actor, she did furnish one article of her costume which was special. It was a starburst brooch, set with a cluster of 8.5 karat diamonds. This was no costume jewelry. Montgomery admired the piece, often remarking on how lovely she found it. When Moorehead passed away in 1974, she willed her brooch to her onscreen daughter.
