Sorry, but if a woman puts much emphasis on a ring (and it's value) - she's pretty superficial/driven by her instinctive mind. Here's an analogy - if you think that a little bit of extra fat on her hips is a deal breaker and she's not a fitness fanatic type of girl - you will get issues eventually. Here's the same, if she's into "lots of money", you may experience some issues in the future (if you aren't going to get seriously rich).
Anyway, if you have at least some common sense - you should know her views and values by now.
