For saying the Rosary anywhere and everywhere. Ideal for slipping on to your finger in your pocket as you walk along or as you wish.To use a rosary ring, you can: 

Make the sign of the cross: Turn the ring so your thumb touches the crucifix and recite the Creed and Our Father. 

Move to the beads: Turn the ring to the right (left if you are left-handed) until your thumb touches the beads three spaces from the cross. 

Recite prayers: Move your thumb along the beads, reciting prayers as you go. 

Pray the Glory Be: At the end of each decade, pray the Glory Be and optionally the “O My Jesus” prayer. 

Pray closing prayers: After five decades, pray the closing prayers and end. 

Rosary rings are a way to have a rosary on hand and use it to count prayers while praying anywhere. Some people like to wear their rosary ring on their index finger so they can move it around easily with their thumb while praying.
