Sphene

Sphene, also known as titanite, is a mineral renowned for its exceptional brilliance and fiery dispersion of colors when properly cut as a gemstone. Its name is derived from the Greek word “sphenos,” meaning wedge, due to its characteristic wedge-shaped crystals. Sphene is typically found in metamorphic rocks and is distinguished by its yellow to brownish-green or blackish-brown coloration. It is valued in the world of gemology for its dispersion, which refers to its ability to split white light into its spectral colors, creating vibrant flashes of color known as “fire.” This mineral is treasured by collectors and gem enthusiasts for its unique optical properties and distinctive appearance.
