A promise ring is a symbol of commitment that does not have to mean marriage, while an engagement ring is a promise to marry. Promise rings are usually simpler and less expensive, and many people wear them on the ring finger of the right hand, or on the left hand until they get engaged. Engagement rings usually have a more prominent stone, often a diamond, and are traditionally worn on the ring finger of the left hand, where the wedding band later joins them.
This guide explains what each ring means, how they differ in style, cost and finger, what to do with a promise ring after an engagement, and how to get the size right.

What a Promise Ring Means
A promise ring can mean many things, and the couple decides what it stands for. It might be a sign of commitment in a serious relationship, a promise to get engaged later, a symbol of loyalty while living apart, or simply a way to mark a special moment. Promise rings are also sometimes given between friends or worn as a personal promise.
What an Engagement Ring Means
An engagement ring has one clear meaning: the couple plans to marry. It is usually given during a proposal and worn until the wedding, when the wedding band is added. Read what hand the wedding ring is worn on for how this varies around the world.

Style, Metal and Cost
Promise rings tend to be lighter and simpler: thin bands, small stones, birthstones, engraving, or heart and infinity designs. Sterling silver, gold, titanium and tungsten are all popular. Our comparison of tungsten vs titanium vs gold explains how these metals wear.
Engagement rings usually feature a larger center stone in gold or platinum. Many couples now choose lab grown stones to stretch their budget. See lab grown vs natural diamonds to compare.
