Judy and Bobby came through again with a lightning fast turn around. It’s lighter than I anticipated (great thing) and looks fantastic! You won’t be disappointed. Thank you.

Very lightweight and unique! Love it

I bought this for my finacé since he wanted a lightweight dark colored ring that would be barely noticable as he isn’t a big jewelry person and he absolutely loves it! To use his words, “It’s like I’m wearing nothing at all! ….Nothing at all…nothing at all…” (Stupid sexy Flanders) The shipping was incredibly fast and the craftsmanship of the ring is just like the pictures. If for whatever reason we need to get it replaced, I’m definitely choosing this seller again!

I can’t express how happy we are with this ring and company. The ring is elegant and rustic all in one, the hammered look gives a rustic unique look and feel. The ring is smoothed out and polished, it looks like that there are not ruff edge and it has a slight shine to it. Very light weight witch is best for men that want to work out or work with hands a lot. Most importantly the customer service is above and beyond. 

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.
