The four rings in a relationship are the promise ring, the engagement ring, the wedding band and the eternity or anniversary ring. They are a popular tradition, not a rule, and each marks a different stage of commitment.
Quick answer: promise ring, then engagement ring, then wedding band, then eternity or anniversary ring. Engagement and wedding rings traditionally go on the left ring finger.
What Are the 4 Rings in a Relationship?
| Ring | What it means | When it is usually given | Where it is worn |
|---|---|---|---|
| Promise ring | Commitment or exclusivity, with no set wedding date | Once a relationship moves past casual dating, such as an anniversary or before a long-distance period | Left ring finger, or the right hand to avoid confusion with an engagement ring |
| Engagement ring | A proposal and intent to marry | At the proposal | Left ring finger |
| Wedding band | The marriage vows, unity | At the wedding ceremony | Left ring finger, closest to the heart |
| Eternity or anniversary ring | Milestones and continued love | After the wedding, such as an anniversary or the birth of a child | Flexible: stacked on the left hand, or on the right hand or another finger |
Based on common ring traditions. Customs vary by culture and personal preference.
1. The Promise Ring
A promise ring marks the start of commitment without a wedding date. It is often given on an anniversary, birthday or before a long-distance separation. Many people wear it on the right hand so it is not mistaken for an engagement ring. See our promise ring size chart.
2. The Engagement Ring
The engagement ring signals a proposal and the intent to marry. Getting the size right matters most here, especially if the proposal is a surprise. Read how to find an engagement ring size, tips for accurately guessing ring size and the engagement ring size chart. For the budget side, see how to choose a lab-grown diamond ring for your budget.
3. The Wedding Band
The wedding band is exchanged at the ceremony and is worn on the left ring finger, with the engagement ring stacked above or beside it. Wide bands can fit tighter, so read understanding wedding band sizes before ordering.
4. The Eternity or Anniversary Ring
An eternity ring has stones around the band, while an anniversary ring marks a milestone year. It is usually given after the wedding. It can be stacked with your other rings or worn on its own, so size it for the finger and hand you plan to use.
What Is the 3 Month Ring Rule?
The three-month rule is the idea of spending about three months of salary on an engagement ring. According to Brilliant Earth, it dates to a 1930s De Beers campaign that suggested one month, and became two to three months by the 1980s. It is a marketing-era guideline, not a requirement. Our guide to choosing a ring for your budget shows how real average spend compares.
How to Size Rings You Will Wear Together
- Same finger: use one size for rings worn together, then check that the stack is comfortable.
- Wide or stacked bands: they feel tighter, so you may need a half size up. See finding the perfect fit in between sizes.
- Different fingers or hands: measure each finger separately.
- Check the fit: a ring should pass the knuckle and sit snugly without leaving deep marks. Read how rings are supposed to fit.
