From a woman's point of view, I think the old tradition of spending two months salary on a ring is BS.
I think the ring you choose should not be based on how much it costs (unless of course it's outrageously priced and then I'd say, don't buy it)
It should be based on what you think your future wife would like, be proud to wear etc.
Two months salary on a ring? a RING! You can't eat it, you can't live in it, you can wear it, but it goes on your finger and doesn't cover any other part of your body.....you get what I'm saying.
off my box now
The ring you chose is very pretty btw
