Neil Lane on Instagram: "A rare Tiffany & Co. treasure: an over 100-carat carved emerald Medusa set into a gold lid, perfectly fitted with turn-of-the-century precision. Likely a special commission, it may even have been procured by Tiffany’s famed gemologist George Frederick Kunz, who was fascinated by historic emeralds and often wrote about legendary carved stones from Mexico and Mughal India.
