Tourmaline is a vibrant and versatile gemstone known for its wide range of colors, which can span from deep greens and blues to vivid pinks, reds, and even multi-colored varieties. This boron silicate mineral is prized not only for its beauty but also for its unique ability to become electrically charged when heated or rubbed, a property known as pyroelectricity. Found in locations around the world, including Brazil, Africa, and Afghanistan, tourmaline is often used in fine jewelry and is believed by some to have metaphysical properties, such as promoting emotional healing and protection. Its rich color diversity and durability make it a favorite among gem collectors and designers alike.
