This has to be the coolest ring of all time. I don’t know why I am so fascinated with it, probably just the intricacy and attention to detail that had to go into machining this thing to be so small yet fluid. The ring has a set of gears that allow you to rotate the upper and lower portions of the ring freely. This is like a high tech version of the “One Ring”. Let’s be honest I think we would all be petting our rings and calling them precious if they were all this cool.
