titanite

Calcium titanium mineral

Titanite is a mineral composed of calcium titanium silicate, typically forming wedge-shaped crystals in yellow, green, or brown.

Valued by mineralogists for its high refractive index and strong dispersion, it produces brilliant flashes of color when cut as a gemstone.

In that context, it's often called sphene.

Titanite occurs in metamorphic and igneous rocks and serves as a source of titanium dioxide.
