A promise ring literally means a "ring of promise." It is often given before an engagement, at a milestone or anniversary in a relationship, as a sign of a future commitment. This article explains its meaning, how it differs from an engagement ring and how to choose one, and introduces the bridal brand of the same name, PROMISE RING.

How it differs from an engagement ring

  • Promise ring: no fixed rules; an easy way to mark your relationship or a future promise, often worn as a pair
  • Engagement ring: given as a promise of marriage, usually set with a diamond

How to choose

  • Budget: stay comfortable, and consider whether you plan to buy engagement and wedding rings later
  • Material: for daily wear, a material resistant to scratches and deformation is reassuring
  • Design: ease of stacking and how it will pair with future wedding rings
  • Engraving: whether you can add an anniversary or message inside
