A fascinating fact about bi-color tourmaline is that its unique coloration results from variations in its chemical composition and growth conditions during formation. The transition from one color to another within the same crystal occurs due to changes in the mineral's composition, such as shifts in the presence of iron, manganese, or other trace elements. These variations create stunning patterns and gradients, making bi-color tourmaline a captivating and sought-after gemstone among collectors and jewelry enthusiasts.
