Thank you Roy, that is kind of you to say.
I used metal stamps for the impressions cut those out with my saw and then filed them and then sweat soldered all the elements (except the bezel and bail and dangle loop) at the same time to the backplate.
The bezel was soldered first with hard solder, then all the elements were done with medium solder and the bail and loop and trademark/925 stamp attached to the backplate with easy solder.
Having the pieces cut out is rather nice as you can experiment a bit with the overall layout and decide which you like best. Originally I had envisioned the stone to hang horizontally but then when I did the layouts and grabbed a pic of them, it was easy for me to decide which I preferred.
