Bi-color Tourmaline is a striking variety of tourmaline that displays two distinct colors within a single crystal. These colors often transition smoothly or sharply, creating a natural gradient or banded effect. Common combinations include pink and green (often called “watermelon tourmaline”), but other mixes like blue-green or pink-yellow also occur.
