I got my hands on another piece of that interesting albite feldspar, and was going to cut my "Electric Feel" design. The outline fit perfectly, but unfortunately, the rough was too shallow. So, I kept the outline and wrote a new stone. Works in materiasl from feldspar to CZ (RI = 1.52 - 2.16), but could use optimizing in higher RIs. Suggested size = 12-20 mm
