Green Elbaite is the most common colored variety of the tourmaline group, highly prized for its vibrant spectrum from light mint to deep forest green. Collectors look for well-terminated, striated prismatic crystals often found in pockets within granitic pegmatites. It is easily identified by its distinctive vertically striated crystal faces and lack of cleavage.
