Functional jewelry is relatively hard to come by, so it’s a no-brainer that we’d jump on Kinekt’s Gear Ring in a heartbeat. If you’re wondering, yes, we do consider moving parts as “functional”, even if it doesn’t do anything other than spin, help pass the time – and, obviously, look damn cool. The gears as well as all other parts on the ring are made of surgical grade stainless steel (no nickel allergies to worry about) and comes in all sizes between 5 and 20.
