- Check the printed ruler measures exactly 80 mm.
Method A — Measure a ring
Lay a ring you own over the circles. The matching circle is your size.

Built for real life, not just photos
Tungsten carbide is about 4× harder than titanium and second only to diamond in scratch resistance — and every ring 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 — 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 the band. Shipped 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.

Frequently asked questions
Is tungsten good for a wedding band?
It's one of the most popular metals for a wedding band 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 — every ring comes with free size exchanges, so your size is guaranteed to end up right.
Can a tungsten ring be resized?
We do something even better — free size exchanges. Instead of cutting and stretching your ring the way traditional resizing does, we simply send you a brand-new ring in the right size. Your ring stays flawless, and the exchange is free.
How does the free engraving work?
Add names, dates, or coordinates — engraved inside the band before it ships, free on every ring (a $30 value). Personalizing your ring adds about three business days, and it's worth every one of them.
Does it come ready to gift?
Yes — every ring arrives in a gift-ready ring box, with free US shipping on every order. Add the free engraving and it's a finished gift the moment it lands on the doorstep.
