Have you ever seen that old model of the atom, the three concentric ovals that were used frequently back in the 60s? I decided to take that image and model it into the crown of a stone, and I think this was pretty successful. Works in materials from beryl to CZ (RI = 1.58 - 2.16) with no changes, but I prefer leucogarnet. Suggested size = 8-12 mm
