Here's how to turn a bar of titanium into a ring with LED-illuminated jewels that light up when they're near a power source. One: fall in love. Two: a bunch of other stuff. Three: boom, magic-ring.
Ben Kokes did all three of these things. The result was a ring with an inductive loop – a copper coil assembly, hidden inside – that causes the stones lining the outside of the band to light up when the ring comes within close proximity of an induced alternating magnetic field. Probably the coolest ring-related craftsmanship we've seen since that guy who forged his own wedding band out of a meteorite.
