This is what's called a fidget ring.  This ring has three interlocking spur gears that rotate when the center gear is rotated. The ring part was designed to be a normal feeling ring. You'll have a hard time not playing with it while it's on your finger.

The ring shown is a size 8 and is 6mm wide.  It will come in Brushed finish shown.


In My Humble Opinion:
      Works well in brushed.
