Continuing on our theme of geology are these really fantastic magnetic rings from Laurent Milon. The rings were created by freezing iron powder, and then cast in layers of nickel, silver and copper. Th ultimate effect is rather exciting looking, like gnarled pieces of coral floating in the water. It’s also cool that there’s a little video so you can see the process. How Laurent dreamed this up, I have no idea, but they turned out fantastic. I’d be careful if you ever wear one of these though, they look a bit dangerous!
