Wrong size? No stress. Just reach out and we'll get your exchange or return moving. We'll send you a prepaid return label to make it easy, and we turn things around within about 3 business days of your ring reaching us.
Engraved rings 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.
A quick heads-up: international orders are final sale. Questions about anything? Check the full Returns & Exchanges policy, or just message us — we're happy to help.
It's one of the most popular men's wedding band 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 — every ring comes with free size exchanges, so your size is guaranteed to end up right.
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.
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.

Yes — this band pairs into the Lunara couples sets, with her crescent-moon moonstone ring made to match. You'll find them next to the add-to-cart button.
