Our original carbon fiber ring was the very first ring we created back in late 2003. This ring is a little less than 3/8" wide or slightly wider than 9mm across its face. While the ring is one of our most basic designs it is also our biggest seller. The simplicity of this design really shows off that beautiful 2x2 twill carbon pattern we all love. The Original carbon fiber ring features a very durable semi gloss exterior. No coatings are used in any of our rings. Each ring is individually wet sanded through 10 stages of sanding with a final application of buffing compound. We offer rings in standard sizes 4.5-13.5 in whole and half sizes. We do not offer 1/4 sizes at this time. If you don't know your size please visit a your local jeweler and get sized. This only takes a few minutes and most jewelers are happy to help you even if you don't buy from them. Please do not guess on your size so that you can start wearing your new ring right away. This ring is made to order and usually takes 2-3 weeks to ship.
