Tardis engagement ring box

The picture shows us one of the 33 best geeky stuff that you can purchase on etsy. One of those cool geeky items is apparently a Tardis engagement ring box. The picture shows what looks like a blue engagement ring box with a caption beneath the cover that says for the girl who waited and beneath it are what seem to be engagement rings. The band seems to be made out of gold and the stone is blue as is the colour of the box. The box seems to have some contraptions about which make it geeky in that sense.
