Composed of 18K gold, glass, enamel and diamonds, this René Lalique frog and ivy flower necklace dates from circa 1902-1903. It is designed as a series of 11 molded green glass frogs joined by stylized green champlevé enamel ivy vines highlighted by diamond flowers. An heirloom passed down in the Lalique family, this unique and mysterious necklace, one of his early experiments in glass, links Lalique to the work of subversive artists working in literature, poetry and dance in fin-de-siècle Paris.
