The 7mm wide Double Deluxe is a combination of two of our most loved carbon fiber rings, the Forty Five and Simplex. The machined groove is slightly offset and looks amazing against the 3K carbon fiber weave. The Double-Deluxe features a semi gloss polished finish that is beautiful and durable. 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 this ring in standard sizes 7-13.5 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.
