A couple thousand.
I think a guy should pay for the ring with cash. None of this financing stuff. I mean, what's good about when you're married, getting a bill from the jeweler and having to pay a certain amount per month. What if the husband isn't working at the time? It's like the wife paying for her own ring. That ain't right.
Some girls care, some don't. It's all in their personality. I don't think women need to be super extravagant, or expect a $10,000 ring. But I figure, my boyfriend currently makes (earns, pre-expenses, bills, etc.) about $600/week. That's why I let him buy my coffee or dinner when we go out; he can afford it. I also think that a man who makes $2400+ a month, can afford to buy a really nice ring. I want something that's going to handle like 60-70 years of marriage, life, wear, tear, etc. We've already established that it will be platinum, not gold or white gold. And he also wants a platinum band as well, it's a mutual thing.
So.. like someone already said, *Communication*... within reason.
