Thanks so much for the advice. If I sell the ring can I use that money to help with the costs of the ring or wedding ceremony? Or should I not use it on the wedding but can use it on mundane things like Princess Cutekitten suggests? Or is it best to give the ring back or donate it?

My parent gave it to me hoping it would help with the wedding-related costs, but if even using the money from it brings the karma / energy from their marriage into my new household and I can't change that, I'd prefer not to.

Luckily I found out there are a couple sources of aquamarine and other beryls in my state and have now found out that people still go rock-hunting in the old mines and near them and there is a place that cuts and polishes these stones, so I can get some aquamarine that hasn't been mined with child or slave labor or lots of nasty environmental consequences.

Thanks again!
