So it might seem a little (or a lot) geeky at first, but the mechanical engagement ring with hidden diamond by John Weldon could hold a lot of appeal for people who appreciate little gems with high tech components.
With the press of a button, the titanium wings covering the top of the mechanical engagement ring shoot to either side to unveil a small, yet dazzling, diamond.
Every time she wants to flaunt her John Weldon rock, she'll be able to trigger the doors open, just like Dr. Evil in his space shuttle.
