Tourmaline exhibits strong pleochroism, which means its crystals can exhibit different colors depending on the angle from which they are viewed. Most red, pink and brown to yellow tourmaline is colored by manganese, while iron and titanium can result in greenish to bluish-black colors. Lithium impurities can result in just about every color, including blue, green, red, yellow and pink.顯示較少內容
