How much should you spend on an engagement ring?

Poll of the Day

I got married at 21 and was pretty poor. I believe her engagement ring was like 150 but it was pretty and the thought was what counted. I picked it out myself though. Its a flower white gold Canada sourced diamond ring. I bought her a more expensive ring a few years later and she literally wore it twice. Our birds like to pick at things so it just stays in the safe which is boring but whatever.
