Tourmaline is a captivating gemstone known for its remarkable diversity in color and properties. It is composed of complex boron silicate minerals, leading to a wide range of hues, from vibrant pinks and greens to deep blues and black. Often valued for its aesthetic appeal, tourmaline is also admired for its metaphysical properties, which are believed to promote healing and balance. With its hexagonal crystalline structure, tourmaline exhibits exceptional brilliance and durability, making it a popular choice for jewelry. Its unique ability to exhibit pleochroism—changing color when viewed from different angles—makes each tourmaline piece truly one-of-a-kind.
