I'm getting at the point that the price tag doesn't matter that much; you can either manage with a cheap gift or spend a good amount. But the latter is only advisable if you're sure that this is the person you're going to build a future with, and you both (I emphasize, not just you, but both of you) have certain joint plans.

By the way, here's a sound piece of advice that I'll strongly reiterate. Never spend money on expensive gifts (expensive in relation to your budget, not based on some made-up criteria) if you're not sure you'll get what you want in return. It's better to buy cheap trinkets – of course, you need to choose them with taste so they look good, but still.
