The Sahara is the latest addition to our Ultra limited series of Crazy Fiber rings. Each Sahara ring will come with a certificate of authenticity as well as a very special 3D printed ring box. When this material is gone it's gone forever. Crazy Fiber is imported from our friends in Russia. Crazy Fiber is very similar to Micarta which is a durable material manufactured by laminating layers of linen fabric with dyed resins. Each ring pattern is like a finger print so your ring will be similar to that pictured but unique at the same time. As you study The Sahara you'll see a layering of rich earth tones found in the African desert. The Sahara is 10mm wide x 3.1mm thick. I can decrease the width to suit your preference but I will only decrease the thickness to as little as 2.5mm to maintain structural integrity. I want it to last. Besides, the chunky design compliments the material very well don't you think? I make this ring in standard fit sizes 7-14 in whole, half, and quarter sizes. 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. If you get the size wrong we can make this ring a little larger but not smaller. No refunds will be given for sizing reasons on this ring since material is extremely limited. This ring ships in 3-4 weeks.
