The Rothschild Egg (1902) is unique because it contains a built-in clock and an automaton. Every hour, a tiny diamond-studded cockerel emerges, flaps its wings, and crows—a playful Easter surprise hidden inside a jewel-covered masterpiece.
Unlike most Fabergé eggs, this one was not made for the Russian royal family. Instead, it was a gift from the Rothschild banking dynasty. In 2007, it set a record when it was sold for over $18.5 million, making it one of the most expensive Fabergé eggs in history.
