Fun, an engagement ring that plays a 20 second audio clip “Shelina, I’ll love you forever. Marry Me!…Shelina, I’ll love you forever. Marry Me!” made by artist and inventor Luke Jerram.
100 lbf/in² of pressure was required to cut the silver ring, using a vibrating diamond stylus. The ring is also a homage to Thomas Edison who made the first sound recording machine – the phonograph in 1877.
Using the ring, I proposed to Shelina in a hot air balloon over Bristol in 2005. We’ve since got married and had 2 children Maya and Nico.
Much better than marketing driven expensive diamonds, in my opinion.

Very cool! Definitely a unique way of proposing.
Love it! Super romantic and unbelievably creative. I really wish this were the rule rather than the exception. Diamonds, IMO, are pretty “blah”.
A talking ring, who would have thought! dude you are very clever and creative. Although I don’t reckon i’ll be using a similar technique when i propose to my girlfriend!!
This feels incredible, provided you already have a girlfriend:)
