I Have No Idea How This Wedding Ring Works; It’s Still Cool

Ben Kokes went through ten prototypes for this ring before he came up with one worth presenting to his fiance Mary, “because doing things in the most complicated way possible is just what he does to show the love.” Those are real white and blue gemstones illuminated with LEDs, but they only light up when the ring is near an “induced alternating magnetic field.”

Now I’m going to be honest with you: I don’t know what that means. But if Kokes’ process, documented on his website, is any indication, it’s very impressive.
