These earrings are a glowing tribute to Marie Curie, the first female Nobel Prize winner in physics. Etched with handwriting from Curie's own lab notes, these earrings feature the atomic weight of radium (Ra = 223.3). Radium, the element discovered by Curie and her husband, inspired the fluorescent color that makes these earrings so much fun to wear. Show off the glow during the day or under a blacklight—where they really go bananas!
