Tourmaline is a unique gemstone known for its wide range of colors and fascinating physical properties. It is a complex boron silicate mineral that forms in a variety of geological environments, including igneous rocks, metamorphic rocks, and sedimentary rocks.
One of the most distinctive features of tourmaline is its ability to exhibit multiple colors within a single crystal. This phenomenon, called “pleochroism,” is due to variations in the concentration of elements within the crystal structure. Tourmaline can come in a range of colors, including green, pink, blue, red, yellow, and black.
