I am by no means a jewelry aficionado, though I did stay up late as a child watching reruns of ocean explorer Jacques Cousteau, and I once owned an honest-to-god metal detector that helped be locate enough rusty nails to build a house. I think that gives me enough cred to post these rings by Japanese designer Yasushi Jona. The rings are new, but have been corroded to look as if just scooped up from a shipwreck on the sea floor. One even contains an embedded shotgun shell. (via lost at e minor)
