Purity rings are a type of ring that symbolizes a commitment to abstinence from sexual activity until marriage. They are often worn on the ring finger of the left hand, but there is no strict rule or tradition that specifies which finger the ring should be worn on.
Some people choose to wear their purity rings on the ring finger of their right hand to distinguish it from an engagement or wedding ring. Others choose to wear it on a different finger altogether, such as the middle finger. Ultimately, the decision of which finger to wear the purity ring on is a personal one and can vary depending on cultural or personal beliefs.
The important thing is not the finger on which the ring is worn, but the meaning and intention behind wearing it. Wearing a purity ring is a personal commitment to remain abstinent until marriage, and can serve as a reminder of that commitment.
