How do I measure my ring size?

First, print out this guide and use it to measure your finger.

Next, order your ring and add the ring sizer 3-pack. You'll get three sizes: your chosen size, one 1/4 size up, and one 1/4 size down. Try them at home to find your perfect fit.

Ring sizers are made precisely to match the specifications of the ring you order.

How accurate are the ring sizers?

Our metal ring sizers are designed to mimic the real ring experience and include 1/4 options making them the most precise sizing option available.

Do I have to return the ring sizers pack?

Nope, these are yours to keep.

What if the ring does not fit?

No worries, you can send it back for a resize or exchange.

Some limitations and fees may apply. Learn more.

Can the design be customized?

Yes! We specialize in custom designs.
You can share your ideas and request a quote here.

Can I use my own materials?

Yes. We can use heirloom gold, ashes, sand, shells, or other sentimental items to create a unique ring.

Are the rings waterproof?

Yes. Our rings are coated with a waterproof resin, protecting materials like wood, antler, and minerals. You can wear them in water without worry.
