Me, a piece of sterling silver wire, a blow torch and a tourmaline.....
(and my messy workbench!)
I'm basing the design and setting of the ring on the natural shape that the tourmaline grows in and also the finished step cut of the stone.
Here's the finished Mock up/test piece/notes
The tourmaline stretches across the finger, so you cant see the setting from directly above, only the stone.
