What is a chastity ring?
Wikipedia does a good job here: Purity rings, or chastity rings originated in the United States in the 1990s among Christian affiliated sexual abstinence groups. The rings are sold to adolescents, or to parents so that they may be given to their adolescent children as gifts. It is intended that wearing a purity ring is accompanied by a religious vow to practice celibacy until marriage. The ring is usually worn on the left ring finger with the implication that the wearer will remain abstinent until it is replaced with a wedding ring. There is no particular style for purity rings; however, many worn by Christians have a cross in their design in reference to Jesus Christ. Some rings contain a diamond chip or other gemstone and/or “Love waits” embossed somewhere on the ring. Others also wear the ring on their right fingers, claiming that the rights of a having rings on the left ring fingers belong solely to their future spouses.
