Bottom Line Recommendation: 

Eternity bands (also known as eternity rings) make meaningful gifts for anniversaries, birthdays and other special celebrations.

The style and setting you choose is mostly based on personal preference, with options ranging from platinum pavé settings like this one to white gold rings like this eternity band. If the eternity ring will be worn next to an engagement or wedding ring, you’ll want to match the style and metal as closely as possible.

We highly recommend purchasing your eternity ring from a reputable vendor like James Allen or Blue Nile to ensure both the diamonds and jewelry are of high quality.

Eternity Rings: The Fundamentals

A eternity band, also called an eternity ring or infinity ring, is made of precious metal set with a complete loop of diamonds. With its endless circle of diamonds, a ring of this type is designed to represent never-ending love.

Because the diamonds of an eternity ring circle the entire finger, this type of ring offers an extra sparkle. Alternative styles of diamond eternity rings contain diamonds set across the face of the ring only and are known as half-eternity rings.

Regardless of which style you choose, it’s customary to wear an eternity ring on the left hand ring finger. If the ring is given to you as a milestone anniversary gift, you can wear it between your wedding ring and engagement ring, or in any arrangement that looks attractive to you.

Where to Buy a Diamond Eternity Ring

Just like when you’re shopping for an engagement ring, you’ll want to buy an eternity ring from a reliable, reputable jewelry vendor. Based on our extensive experience, we recommend the three following vendors for eternity rings, engagement rings and other fine jewelry:

Determining the Quality of an Eternity Ring

There are three important aspects to consider when you’re evaluating the quality and beauty of an eternity ring. The first is the diamonds used in the ring. The second is the setting, while the third is the type of precious metal used to make the band.

Eternity Ring Diamonds

The gemstones used in a diamond eternity ring are significantly smaller than the center stone used in an engagement ring. In fact, they’re so much smaller than it’s generally not economical for them to be graded and certified like an engagement ring diamond.

For example, the cost of grading and certifying the 14 diamonds used in a typical eternity ring would be about one thousand dollars. This would greatly increase the cost of the ring and make it far less affordable for customers.

Because of this, you won’t get certifications for diamond eternity rings. This makes it important to buy an eternity ring from a reputable vendor like James Allen or Blue Nile, ensuring you get diamonds that are of a high standard.

Much of what you’re paying for in an eternity ring is the jewelry’s craftsmanship and style. The way the jewelry is formed and the way the stones are set makes a tremendous difference in the beauty and quality of the ring.

For example, the level of the jeweler’s expertise and the amount of time and care invested in an eternity ring will be much higher with a vendor like James Allen or Blue Nile than a less reliable, less well-known vendor.

When reviewing diamonds yourself, watch for the level of brilliance (the amount the diamonds sparkle and reflect white light). You’ll also want to check that the diamonds are eye clean (this means they don’t have any glaring, visible blemishes).

To evaluate color, check that the diamonds appear white in relation to the setting. For example, these F to G colored diamonds appear white in their 14K white gold setting. With a yellow gold setting, the diamonds can be less white than what’s necessary with a white gold setting.

Eternity rings come in various total carat weights (in the industry, this is shortened to CTW) for every taste and budget.

If you’re not sure where to start or would like assistance in reviewing and comparing diamonds, feel free to contact our experts.

Eternity Ring Styles and Settings

Diamond eternity rings are available in prong, channel, bezel and flush settings. If you want to pair the band with an existing engagement or wedding ring, try to match the style and metal as closely as you can to your existing rings.

Many diamond eternity rings use prongs for their settings. A prong setting allows more light to reach each diamond. It also increases the number of angles from which light can reach each stone, resulting in greater brilliance.

This 14K white gold eternity ring is an example of a prong style setting, while this ring uses a pavé setting. The most popular diamond shape for eternity rings is the round diamond, though unique styles are available, such as this Asscher cut eternity ring.

Eternity Ring Metals

Like other jewelry, there’s no “best” metal for a diamond eternity ring. Instead, the type and color of metal you choose — typically platinum, white gold, rose gold or yellow gold — is usually based on your personal tastes and preferences.

Eternity rings are designed for everyday wear, meaning the materials used to create them tend to be durable. Both 18K and 14K gold in all colors, as well as platinum, are more than durable enough to be used for an everyday wear eternity band.

Our guide to gold and platinum goes into more detail on the key differences between these two popular metals. You can also learn more about 14K gold here.

When to Buy Eternity Bands

Diamond eternity rings make for meaningful and stunning gifts. Because of their classic design and popular appeal, they’re often regarded as family heirlooms and tend to be passed down for generations.

Commonly given for milestone wedding anniversaries (i.e. 5th, 10th, 20th, 25th), eternity bands can also be a gift for:

  • Special birthdays
  • The birth of a child
  • Valentine’s Day
  • Celebrations of an exciting milestone
  • Retirements
  • Christmas, Hanukkah and other holidays

How to Determine Sizing for an Eternity Band

Since eternity rings go on the left ring finger, it’s easy to determining the right size by using the person’s existing wedding ring or engagement ring.

To find the size of an existing wedding or engagement ring, measure the inner diameter of the ring, then compare it to a ring sizing chart. You can also wrap a thin piece of paper around the person’s finger, then mark the spot where the paper overlaps with a pen or pencil.

It’s also possible to measure someone’s ring size using a printable ring sizer. Finally, if you’re not confident measuring someone’s ring size on your own, you can go to a jewelry store for a professional measurement.

If you’re unable to obtain the size and want the ring to be a surprise, consider having a close friend or family member of the person you’re buying the ring for sneak the information.

Famous Eternity Bands

Dating back to ancient Egypt, eternity rings — although not always in the diamond and precious metal form we’re familiar with today — have likely been worn for almost 4,000 years.

  • Other celebrities known to wear eternity bands: Jennifer Garner, Blake Lively, Jessica Biel and Mariah Carey.

Frequently Asked Questions About Eternity Rings

What Finger Does an Eternity Ring Go On?

There’s no “right” finger for an eternity ring, meaning you can wear your ring on any finger you like. However, most people opt to wear their eternity ring on the same finger as their wedding ring and engagement ring.

By choosing a precious metal that complements the engagement and wedding ring, a diamond eternity ring can add an extra special look to you or your partner’s ring finger.

What Does an Eternity Ring Symbolize?

Eternity rings are designed to symbolize love and commitment, with the continuous circle of diamonds symbolizing continuous, eternal love. This originated in Ancient Egypt, with simple carved rings showing up in Old Egyptian hieroglyphics and archaeological sites.

When Do You Traditionally Give an Eternity Ring?

You can give an eternity ring to mark a special time in a relationship, such as an anniversary or the birth of a child. It’s also totally fine to give a diamond eternity ring to mark a big achievement, a special holiday or a major milestone such as retirement or a significant birthday.

Can You Give an Eternity Ring as an Engagement Ring?

Although it’s not traditional, some people choose to give an eternity ring as an engagement ring in place of a conventional diamond ring. It’s also becoming increasingly common to present an eternity ring during the proposal, then choose a traditional engagement ring together.

There are no absolute “rules” of giving an engagement ring, meaning you can give any ring you and your partner will feel comfortable with. If you think your partner would prefer a eternity ring to a conventional engagement ring, don’t let tradition stop you from doing what you want.

Can You Wear an Eternity Ring as a Wedding Ring?

This is another modern custom that’s become particularly common in the last decade. Just like giving an eternity ring as an engagement ring, it’s totally okay to wear an eternity ring instead of a traditional wedding ring. In fact, many people prefer the extra sparkle an eternity ring offers.
