Catholics have carried rosary rings during times of trouble as well as times of extended travel. It is believed that rosary rings originated in the 13th century. In the 16th century, rosary rings were carried in secret because religious persecution prevented Catholics from carrying traditional rosaries.
Rosary rings are not worn on the finger, however can if your fingers are small enough. They are carried in a pocket by travelers and often by members of the military during times of war.
