Bi-color tourmaline is a striking gemstone that features two distinct colors, often seen in a single crystal. This unique appearance can range from combinations like green and pink to blue and green. The presence of these colors is due to the varying concentrations of elements like iron, manganese, or lithium in the crystal structure.

Metaphysically, bi-color tourmaline is believed to balance energies, promoting emotional healing and harmony. It can also enhance creativity and help in decision-making by allowing one to see multiple perspectives. The rarity of this gemstone adds to its allure, making it a sought-after choice for collectors and jewelry enthusiasts alike.
