Cutting Notes
The open C-axis allows for precise orientation of the peach and pink hues. Tourmalines are dichroic, so the cutter should align the table perpendicular to the C-axis for maximum color saturation. The clean rough supports a high-yield emerald cut. Use a standard polishing sequence for tourmaline to achieve a high luster.
Cutter’s tip: Align the emerald cut long axis with the crystal C-axis to optimize color distribution.
