Do you, Crafty Nerd, take this Whovian to be your lawfully wedded wife? To have and to hold, and not leave her on some rogue moon populated by robot succubi with delusions of grandeur? If so, then you'd better have an appropriately awesome, custom-made piece of jewelry to seal the deal. Something like this.
According to Tumblr user Pathetic Peripatetic—who says he "was bored so I made this"—this Police Box-based ring features a tension-set 1CT princess cut center stone. The three round stones form 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.
Don't know if he'll make more, but I'll bet he could be swayed by the entirety of space and time, a reasonable facsimile thereof, or a briefcase full of cash.
