What should I do with my ring?

I've been thinking about my ring and what to do with it.

The way I see it, there are a few options:

1) Sell it. Get the money. Not that it would be a lot, but hey! Or save it for bartering durring the Zombie apocalypse...

2) When I first took my ring off, I went back into the jeweler that we bought it from to get it cleaned. The jeweler told me to brink it back if I ever get re-married and they will add the value of the ring to whatever new ring my future husband and I buy.

3) Save it for my kid? Though that is a little weird...

I don't know. Thoughts? Thoughts? What did you do with your ring and why? Are there options I'm not thinking of?
