Sphene, or titanite, is renowned for its remarkable optical properties. It boasts one of the highest mineral dispersions, with a value of 0.051, exceeding that of diamonds at 0.044. This high dispersion creates a dazzling "fire" within well-cut sphene gemstones, showcasing a spectrum of colors. Sphene also has a distinctive birefringence, resulting in a subtle doubling of facets, adding to its unique charm. Sphene's exceptional optical qualities make it a prized gemstone for collectors and enthusiasts, bridging the worlds of science and beauty.
