Figure 1. Emerald crystals from Colombia (top right), Afghanistan (bottom right), and Zambia (left). Each emerald’s hexagonal prismatic crystal habit has been enhanced by polishing flat the two hexagonal end faces (perpendicular to the crystal’s c-axis) and two or more prism sides (parallel to the c-axis).
