sMIL has started giving away her jewelry. She started by giving me a ruby ring and earrings. They are not even close to my style, but might consider resetting them. Then again I have 2 ruby rings, earrings, and necklace. As a side note I have had more compliments on my e-ring in that past 2 weeks than I have in years.
Re: Has anyone had jewelry reset?
I actually still have original setting, minus the center stone, so I didn't get a credit for it. I'm sure if you asked they'd be able to buy the gold.
Some of the major jewelry store chains do resetting events so you could get ideas there and shop around for jewelers to do the work.
I've never done it personally, although may reset some of my mom's jewelry when she passes. (assuming I'm alive and she gifts it to me)
(I was kidding her when we visited about putting my claims on her stuff - "i love your new earrings, put an imaginary post it on those for me")
