Medici Sapphire

The Medici Sapphire is a priceless jewel worn by Medici brides on their wedding day. Kept secured in the Vault, it is worth more than all the gold put together.

History
Thieves Nazario and Donnola attempted to steal the Sapphire by putting on a play, The Shepherd of Love, to provide them with the opportunity and means to break into the bank when there would be no guards present. They switched it with a fake sapphire from their crown prop and attempted to make off with it but were stopped by Leonardo da Vinci. (Diabolical Acts)
