FAQs

Yes, carbon fiber rings can be engraved. They can also be laser etched although special experience may be required to do so effectively. We do not necessarily recommend it and are not set up to do it.

All carbon fiber, metal, and glass fiber rings come with a lifetime warranty against manufacturing defects. If your ring breaks or cracks due to a defect in how it was made, we'll replace it. You'll need to provide a photo of the broken ring and may be asked to send it back to us.

The warranty does not cover:

  • Damage from accidents, impact, or misuse
  • Normal wear and surface scratches
  • Chips caused by heavy impact
  • Damage from chemicals, extreme conditions, or improper care

Wood rings:covered by aone-yearlimited warranty (not lifetime), because wood is a natural material subject to environmental factors. Damage from moisture is not covered.

Width is personal, but here's a useful guide:

  • 4mm — slim and barely-there. Great for smaller hands or anyone who prefers a minimalist look. The most popular width for our Ultralight rings.
  • 6mm — the classic width. Substantial enough to notice, narrow enough to forget about. Works well on most hand sizes.
  • 8mm — bold and visible. Best for larger hands or anyone who wants the ring to make a statement.

If you're not sure, go 6mm. Most people who agonize over it end up happy with 6.

Yes. If you can't find exactly what you're looking for in our catalog, reach out. We've built rings with specific material combinations, unique widths, custom finishes, and even specific colour requests.

Simple: if you're not 100% happy with your ring within 30 days of receiving it, we'll make it right — no questions asked.

  • Size exchange: Free. We cover shipping both ways (within the USA). For international exchanges, you'll need to cover return postage.
  • Full refund: Available within 30 days of shipment. Ship the ring back to us and we'll refund your full purchase price.
  • Gift orders: If you need more than 30 days because it's a gift, just reach out and let us know. We'll work with you.

Gold rings have special considerations— please read our Returns & Exchanges page for the details before purchasing a ring with gold components.
