Very light, very comfortable to wear.

I wanted a wider wedding band to replace the 8mm ring i had as I have slightly larger hands. I wear XL gloves for reference. I wear a size 11 ring (20.6mm día). I took the recommendation of upping half a size if getting a 10mm wide ring. Glad I did as it fits perfectly and the matte carbon weave looks freaking amazing. Highly recommend and am very much pleased with it.

Our Core Beginnings

All of our rings are handmade in the USA using proprietary processing technology superior to what we originally developed for NASA. We were a composite company first, the rings were created in 2009 when we were unable to find a full carbon fiber ring to purchase. Today our rings are around the world! We love being able to create a one of a kind piece of jewelry. We believe in keeping our prices affordable so everyone has the opportunity to enjoy our craft.
