Lay a ring you own over the circles. The matching circle is your size.
Method B — Finger strip
Cut out the strip, wrap it around your finger, thread the end through the slit, and read your size.

Built for real life, not just photos
Both rings are tungsten carbide — about 4× harder than titanium and second only to diamond in scratch resistance — and every set is backed by our lifetime warranty.
“I needed something that's durable and I don't have to worry about it getting scratched up.”
Guess wrong, we fix it free
Free size exchanges on both rings — we send a brand-new ring in the right size, with a prepaid return label for the old one.
“I had to exchange it twice due to sizing issues (my fault) and was met with amazing customer service.”
The most meaningful part is hidden
A date. A name. An inside joke no one else will get. Free engraving — a $30 value — inside both bands. Shipped together in a gift-ready ring box.
“Rings look so beautiful. Engraving of my wedding song is perfect.”
Designed by an aerospace engineer. Run by a family.
Foreverings started in 2017 when our founder left aerospace engineering to make rings the way he made flight hardware — material selection, tolerances, and final finish held to the same standard.
Years later we're still a family business based in Florida. Every ring is inspected by hand before it ships, and every one is engraved free.

Engraved sets are made just for you, so they can't be returned — but if the size isn't right, we'll take 40% off a replacement so you're not starting over.

Frequently asked questions
What's included in the set?
Both rings — his and hers, each in the size you choose. One purchase covers both of you, shipped together in a gift-ready ring box with free US shipping.
Is tungsten good for wedding rings?
It's one of the most popular wedding ring metals for a reason: tungsten carbide is about 4× harder than titanium, holds its polish for years, and is hypoallergenic. And the fit is always protected — both rings come with free size exchanges.
Can the rings be resized?
We do something even better — free size exchanges, on both rings. Instead of cutting and stretching a ring the way traditional resizing does, we simply send a brand-new ring in the right size. If either size is wrong, we make it right, free.
How does the free engraving work?
Add names, dates, or coordinates to either band — or both — engraved before your set ships, free (a $30 value). Engraving is custom-made just for you, so engraved sets are final sale, and it adds about three business days.
Can I buy the rings separately?
Most of our designs are also sold individually — the set is simply the best value. If you only need one ring, message us and we'll point you to the matching individual listings.
