Size Chart Worried about what size to order? Don't be. If the fit isn't perfect, we'll be happy to exchange it.
Ultra–light weight, incredibly strong, and optimized for the longest glow time possible, the Lume ring combines our proprietary Forged Carbon Fiber with a luminescent interior in a striking design. Unlike the industrial aesthetic of most carbon fiber products, Forged Carbon Fiber features a depth of layers evoking the look of honed marble. Inside, the ring is fitted with a luminescent resin, allowing it to glow brightly after being charged with either a UV light or sunlight. Each ring is handmade in our small shop using only the finest materials available and features our signature comfort fit interior, a more pronounced comfort fit that makes our rings both more comfortable to wear and less likely to ever get stuck on the hand. (Please note that our comfort fit interior makes rings feel slightly looser than a typical ring, so if you are between sizes we recommend ordering down.)
What is Forged Carbon Fiber?
Forged Carbon Fiber is a proprietary material first developed by Lamborghini for use in luxury sports cars. At Carbon 6, we developed our own proprietary process inspired by Lamborghini’s technology to create Forged Carbon Fiber that is optimized for both performance and a beautiful marbled look.
What makes it glow?
For the interior, we looked to the luxury watch industry, which incorporates glowing elements into dive watches and other high-end pieces. Once we found what non-toxic materials perform the best, we developed a proprietary process to optimize for the best possible brightness and glow time.
How long will it glow after being charged?
Glow times vary depending on the strength of the light with which the ring is charged and how long it is charged for. However, when charged with a UV flashlight for 5 to 10 seconds, the ring will glow for one to two hours. The ring can be recharged for 10+ years.
What if I don’t know my ring size?
If you’re unsure of your ring size, order the size you believe is closest to yours and then send us a note at email@example.com. We will gladly include a free ring sizer with your ring when it ships so that if the fit isn’t perfect, you’ll know what size to change to and we’ll get your ring exchanged for you right away.
Guarantee and Return Policy: 90-Day Money Back & Ring Size Exchange Guarantee. If your ring doesn't fit perfectly, we'll be happy to exchange it for the right size. And if any of our products don't meet your expectations in any way, we'll happily replace them or send you a full refund, whichever you prefer.
Delivery: Each Carbon 6 ring is handmade in our small workshop, ensuring that every one is unique and made with care. As a result, our Forged Carbon Fiber rings sometimes take longer to deliver than an off-the-shelf product. If your ring is in stock, we'll ship it within 48 hours. If not, your ring will be made soon in one of our small, hand-crafted batches; however, when that's the case, your one-of-a-kind band may take two weeks to ship. If you have a pressing wedding date coming up, please let us know and we'll do everything we can to get you your ring in time.
