Catholic Prayer Beads, also known as ROSARY beads, are a set of beads used in prayer by members of the Catholic faith. They are composed of a string of beads, usually made of wood or glass, with a crucifix at one end and a medal of the Virgin Mary at the other. The beads are used to count prayers, such as the Hail Mary, and to keep track of the number of times a prayer is said. The ROSARY is an important part of Catholic devotion and is often used during Mass and other religious ceremonies.
