Spend what you can. This is the key though. TALK to your partner and see what is the best outcome. My wife and I spent 1000 on both our rings and spent the rest on the honeymoon and our house instead.
it's about communication and making sure you both put your investment into what matters most to BOTH of you.

I will say though that since you earn 10k in two months your spouse is likely expecting you to spend something similar if she knows how much you earn. It's not about the money. It's about the TIME your spent to earn it. The money you spend 'can' be symbolism for how much you think she is worth to spend the rest of your life with her/them.
