Damn! I just upvoted my own comment again :)

Jewelry:

My husband and I bought our wedding rings with the money my husband received (before we were married) in exchange for a watch I'd bought him. I lost that ring on my honeymoon. I dismissed as irrelevant his suggestion that he buy me an engagement ring. I did buy one for myself,three years before: a faux engagement ring for $6.00. I needed that for work, where I was one of 3 women in a force of about about 250 men. That purchase was purely for self defense.

I definitely share your inclination toward utility.
