Byzantine Eagle Secret Treasure Enameled Egg. Like those originally fashioned by imperial Russian jeweler Peter Carl Faberge, delicately designed eggs like ours have signified affection for over a century. Our own collectible egg, cast in the “lost wax” method, features hand-fired enamel, and a hinged magnet closure. (It even lifts from its base!) Our egg opens from the front and top to hold your tiny treasures and includes slots for photos of your own Czarina.
