Bi-color tourmalines are a type of tourmaline gemstone that displays two distinct colors in a single crystal. These gemstones are prized for their unique and vibrant color combinations, which can range from pink and green to blue and yellow, among others. Bi-color tourmalines are formed due to variations in the mineral composition during their growth process. They are popular choices for jewelry, as they offer a striking and visually appealing contrast of colors within a single stone.
