The diamond engagement ring was invented by a PR company hired by De Beers: http://blogs.static.mentalfloss.com/blogs/archives/21211.html http://blogs.static.mentalfloss.com/blogs/archives/21211.htm... Personally, I got suckered into buying an engagement ring one time, but the engagement didn't take. After lots of searching, I was eventually able to sell the ring for half what I paid for it. I used the money for gas and moved to California :)
