We have 2 options for sizing rings. 

The first and free method is the zip-tie style sizers.

We have to charge $5 for these and refund you when you place your order for your ring.

These are great if you have absolutely no idea what size you need.

These zip-tie style sizers can be accurate if used correctly. You want to put the sizer on your finger so it only just touches your skin, do not squeeze it tightly so to indent your skin.

The sizing zip-ties only show Whole and half sizes. The white sizer shown in the photo below is showing size 11 for example.

The second and most accurate sizing method we offer

is our custom-made for you plastic sizing ring. We make you a custom ring that is the exact width and finger size you want to most accurately represent the wedding band you order from us. 

You want to order the sizing ring in the desired width and size that is available for the ring you are going to order from us. 


We can make all our rings in sizes 5-14

Whole, Half and Quarter sizes are available.

To select, choose width in the drop-down menu, add the ring to the cart, and enter the size needed in the "notes" box.

Your ring made with
Renewable Energy

Your ring is made using 100% renewable power. This is not some paid "credit" that has become so prevalant but quite different indeed. Our shop is offgrid, the only power input comes from our back yard solar array!

Everything went extremely smoothly. Ring was delivered in a timely fashion. It looks very well made and my fiancé loves it. It obviously reflects her personal taste but she also appreciates it being a very clean, beautiful ring.

  1. I ordered a titanium ring for my husband's birthday and it arrived within 10 days! The fast shipping and excellent communication from the Peacefield Titanium team made the whole experience stress-free. My husband loves his new ring and we will definitely be returning customers in the future.

Titanium is a nickel free metal, its hypoallergenic and bio-compatible.

Yes! We can build your ring with any of the wood species seen throughout our store, for example, the ring you clicked has Rosewood and think Koa would look better, no problem, just contact us to discuss your customized ring. This usually doesn't cost any extra!

We seal our Antler and wood inlays with a waterproof finish. With this in mind, it is still best practice to remove your ring if you're going to be spending a significant amount of time in the water. Dry your ring promptly when it gets wet.

No, titanium cannot be soldered to resize like silver or gold ring. We offer free exchange for a different size though to cover any sizing issue with your order.

The average build time from the date ordered till shipped is typically 7 days.
