This is a real first class bone relic of Saint Vincent Depaul. The bone is at least 400 years old. He grants miracles relating to health and wealth as well as depression. He does appear in extreme cases, but even if he doesn't, he still will give health and wealth.
He was born around 1580 in France to a peasant family. He studied theology and the humanities as a young man. After he was kidnapped by pirates and sold as a slave, he converted his master to Christianity. The saintly deeds he is most known for is his treatment of the poor. He took it upon himself to give them medical care and had a soft spot for imprisoned convicts with really bad physical ailments. More details about his life can easily be found all over the internet.
He died in 1660. His body was exhumed decades later and it had not decomposed at all. It remained in a pristine, incorrupt condition. He is one of the most fascinating and famous cases of a saint demonstrating this. His heart, which is still in perfect condition, is still on display in Paris, France.
