With a captivating curvilinear frame showcasing a fiery 5 carat Australian opal, this authentic Art Nouveau antique lavalier necklace is simply swoon worthy. Carrying over a splendid and closely related Belle Epoque heritage, this fabulous necklace was fabricated in period-correct silver topped 14k gold and retains its original patina. Formerly a brooch, the pin was removed and a white gold chain added by the former owners.
