Honestly, if you're even considering this kind of thing... you've got issues.
I was bored and made this. Its a Police Box based ring with a tension set 1CT Princess Cut center stone. The three round stones is the Police Box sign, the two sets of four baguettes symbolize the windows, and a small princess cut below that to symbolize the instructions found on the front of the Police Box.
Wait, wait, wait. You were bored and you made this? I'm not usually one to encourage idleness (in other people), but please run out of ideas again sometime soon!
Japanese design firm Torafu Architects has invented a wedding ring that, like all good relationships, gets better with age! The ring is gold with a silver-plated exterior. As the months and years go by the silver wears off to expose the golden center.
Kind of reminds me of a jawbreaker candy. Except, in this case, by the time you get to the center you're not wondering why you bought it in the first place. Hopefully.
