Get our best-selling Lume ring now with a faceted exterior. 

Each ring is handcrafted in our small shop of Forged Carbon Fiber and our proprietary glow material; both of these materials are made in-house at our Brooklyn shop. The design also 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. 

This ring is available in all of the colors currently offered in our Lume ring. More photos coming soon.

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. 

Unconditionally Guaranteed: 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.
