Nearby resources for *making* jewelry?

[elfword.livejournal.com]

I have several stones from a beach trip with a friend, that look better when wet. I'd like to make jewelry out of them in a way that will keep water locked around either one stone (for a necklace), or several stones (for a bracelet). A custom-sized glass container (that also holds it still on the inside), or shrink-wrapping them in durable but clear plastic, seem like my only options.

Any ideas for people / places nearby that might be able to help me with this?
