F1 Ring

  Size Chart  Worried about what size to order? Don't be. If the fit isn't perfect, we'll be happy to exchange it.  

Designed to conform to the Golden Ratio, the F1 offers a perfectly balanced look and feel in a clean, modern aesthetic. Filament wound carbon fiber creates a high-performance, lightweight exterior with a clean, lightly etched look. Inside, a luminescent interior gives off a radiant glow when charged with a UV light or sunlight. Each ring is handmade in our small shop using only the finest materials available and features our signature comfort fit interior, a more pronounced comfort fit that makes our rings both more comfortable to wear and less likely to ever get stuck on the hand. 


What is filament wound carbon fiber?

Filament wound carbon fiber is created by winding strands of carbon fiber into cylinders, allowing it to be optimized for strength while giving it an etched pattern instead of the industrial-looking woven pattern often seen in carbon fiber products. It’s often used in aerospace technology and missiles.

What makes it glow?

For the interior, we looked to the luxury watch industry, which incorporates glowing elements into dive watches and other high-end pieces. Once we found what non-toxic materials perform the best, we developed a proprietary process to optimize for the best possible brightness and glow time.

How long will it glow after being charged?

Glow times vary depending on the strength of the light with which the ring is charged and how long it is charged for. However, when charged with a UV flashlight for 5 to 10 seconds, the ring will glow for several hours. The ring can be recharged for 10+ years.

What if I don’t know my ring size?

If you’re unsure of your ring size, order the size you believe is closest to yours and then send us a note at We will gladly include a free ring sizer with your ring when it ships so that if the fit isn’t perfect, you’ll know what size to change to and we’ll get your ring exchanged for you right away.

Unconditionally Guaranteed: If your ring doesn't fit perfectly, we'll be happy to exchange it for the right size. And if any of our products don't meet your expectations in any way, we'll happily replace them or send you a full refund, whichever you prefer.
