How about this for the perfect geek-tastic engagement ring?
Working with a jeweller and the vinyl record manufacturer Dubstudios I created this engagement ring for my partner Shelina. The ring has a 20 second recorded message (my proposal) etched onto its surface and can be played back with a miniature record player. The ring is also a homage to Thomas Edison who made the first sound recording machine- the phonograph in 1877
