If you mean bicolour tourmaline crystals, they’re tourmaline crystals showing two distinct colours in the same crystal, often with a sharp or gradual colour transition.
Common combinations include:
Pink + green — especially prized and often called watermelon tourmaline when the colours are arranged concentrically.
Green + blue
Blue + pink
Yellow + green
Black + green
They’re particularly valued when the colour boundary is natural, well-defined, and the crystal is transparent with good lustre.
