The Fountain aigrette worn by Elizaveta Petrovna and her descendants. Elizaveta Petrovna (1709-1761), the daughter of Peter the Great, loved brooches and had many of them made for her in a variety of styles and fashions. This piece in the form of a fountain of sapphires with diamond drops is called an Aigrette and was worn on a hat or as a hair clip. The aigrette comes in a set with massive Fountain earrings. They looked particularly striking in motion.
