Witch’s Heart Brooch. Victorian/Edwardian 15ct turquoise and pearl witch's heart. Circa 1900-10. The tail of a witch's heart twists to one side and is a shape that has been in use since the 15th century. It gained popularity in Scotland in the 17th century when it became known as a Luckenbooth, named for the closed booths in Edinburgh where they were sold as tokens to ward off evil spirits and protect loved ones. Tiny witch's hearts were often pinned to a baby's blanket as protection.
