I think the tradition is that a man should invest a certain amount of resources. And the point is to not buy/get anything useful. A pile of money for a diamond ring is some resources. But there are alternatives: This guy made a wirelessly powered led illuminated ring: http://www.kokes.net/projectlonghaul/projectlonghaul.htm http://www.kokes.net/projectlonghaul/projectlonghaul.htm This guy forged a ring out of meteorite metal: http://io9.com/5907849/this-guy-hand-forged-his-own-wedding-ring-out-of-a-meteorite http://io9.com/5907849/this-guy-hand-forged-his-own-wedding-... Those are both, I would say, much larger investments than $2000 to $5000 dollars in money.
