Haleluia! I finally got the stubborn thing finished! The 20 gauge sheet that I used for the bezel soldered just fine to the base. It was much harder than I predicted to push the bezel walls neatly over the stone...had to take a hammer to the butt of my prong pusher to secure the stone. I was waiting for the jasper to crack in half, but it didn't! And I'm done with it! Now I can finally move on to a new project.
