What ring do Catholic bishops wear?

Ring that bishops wear can be any ring that usually containing an image or a jewel and is worn on the ring figure on his right hand. It is never a ring that is just a simple gold or silver band, but contains a jewel or a few jewels or an image such as a cross, or the bishop's coat of arms, or in the case of a cardinal's ring, an image of the pope's choice when that particular pope named a bishop as a cardinal. For example, Pope John Paul II gave cardinals he named a ring with the image of the crucifixion. The reason why a bishop wears a ring is it symbolizes his marriage to the Church by his ordination as both a priest and bishop. The ring is one of the few visible symbols that represents the office of bishop in the Catholic Church.
