I only want to get a wedding ring that has a microscopic GPS chip so we'd know where to find it when we enter the SS# associated with our ring at ILostMyRing.com. Unfortunately, a GPS-chipped wedding ring won't be around for another few years!
But the premise for a site like that is: Enter the Social Security # of the ring's owner, and the site will give you a map with a blip of your ring's location, accurate down to hopefully 2 feet.
Therefore, when you upload the map with location blip onto your phone, you'll be able to track it down when you go look for it.
(On the phone's ring-finding application-- Red blip: Ring's location, Yellow blip: Phone's location, so if the Yellow blip is atop the red blip, start digging!)
Maybe it got thrown away with the trash; maybe it fell off while sleeping and is just hiding under one's bed. Maybe a pet took it outside while the owner took it off and looked away.
THAT'S WHY ALL WEDDING RINGS OUGHT TO COME EQUIPPED WITH A GPS CHIP.
