Tourmaline

Appearance:

Tourmaline is renowned for its diverse color range, often occurring in multiple colors within a single crystal. It forms in long, prismatic crystals with triangular cross-sections. Colors span the entire spectrum, including black (Schorl), pink to red (Rubellite), blue (Indicolite), green (Verdelite), and multicolored varieties like Watermelon Tourmaline. Its pleochroism means the color can change when viewed from different angles.
