Titanite

Titanite, also known as sphene, is a mineral composed mainly of calcium titanium silicate. It typically forms in igneous and metamorphic rocks and is valued as a gemstone for its brilliant luster and range of colors, including green, yellow, brown, and reddish hues. Its high refractive index gives it impressive sparkle, making it attractive for jewelry. In addition to its aesthetic appeal, titanite is used in scientific applications, such as in optical lenses and as a source of titanium. Although relatively rare, it is appreciated for its vibrant appearance and distinctive features.
