A promise ring is a ring that symbolizes a promise, usually between two people. It can represent many different types of promises, such as a commitment to abstinence from sex or drugs, a pre-engagement or a religious belief.
The most common meaning of a promise ring is a pre-marital commitment. In this case, the promise ring is given as a symbol of love and fidelity. It can serve as a pre-engagement ring for couples who are not ready to begin an actual engagement or marriage. As the relationship progresses and becomes more serious, the promise ring is then replaced by the engagement ring.
Although typically associated with marital commitments, a promise ring can be made up of any type of material and is given in a variety of other situations. Purity promise rings are typically given to children by their parents, and represent the child's promise to abstain from sex until marriage. Purity promise rings are also given to people after completing a rehabilitation, to represent their promise to continue down the right path and not revert back to destructive behaviors.
Religious promise rings are worn by believers or followers of a certain faith to symbolize unity and adherence to that faith's values and tradition.
