✨ What makes Multicolour Tourmaline special?
- Its colours form while the crystal grows: changing trace-element concentrations, oxidation conditions and structural chemistry create successive zones rather than later surface decoration.
- Its zoning can follow several directions: colours may change from one end to the other, form parallel bands, surround an inner core or divide the crystal into triangular sectors.
- Its appearance changes with orientation: Tourmaline’s strong pleochroism may make individual zones appear lighter, darker or subtly different when viewed along another crystal direction.
