Green and turquoise tourmalines are among the most sought-after varieties of this remarkably diverse gemstone group. Their colors range from fresh, grassy greens to vivid blue-green hues, often reminiscent of tropical waters. These stones owe their coloration primarily to traces of iron and other elements within their complex crystal structure.
